LEDs
|
||||
====
|
||||
|
||||
The LX_CPU base board has two user LEDs
|
||||
|
||||
LED1 : Connected to P1[29] RED
|
||||
LED2 : Connected to P0[16] GREEN
|
||||
|
||||
If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in
|
||||
any way using the defitions provided in the board.h header file.
|
||||
|
||||
If CONFIG_ARCH_LEDs is defined, then NuttX will control the 2 LEDs on the
|
||||
WaveShare Open1788K. The following definitions describe how NuttX controls
|
||||
the LEDs:
|
||||
LED1 LED2
|
||||
LED_STARTED OFF OFF
|
||||
LED_HEAPALLOCATE ON OFF
|
||||
LED_IRQSENABLED OFF ON
|
||||
LED_STACKCREATED ON ON
|
||||
LED_INIRQ
|
||||
LED_SIGNAL
|
||||
LED_ASSERTION
|
||||
LED_PANIC
|
||||
LED_IDLE
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
By Default, UART0 is used as the serial console in all configurations. This
|
||||
may be connected to your computer via an external RS-232 driver or via the
|
||||
WaveShare USB ISP/VCOM module.
|
||||
|
||||
As an option, UART1 can also be used for the serial console. You might want,
|
||||
to do this, for example, if you use UART0 for the ISP function and you want
|
||||
to use a different UART for console output. UART1 can be configured as the
|
||||
serial console by changing the configuration as follows:
|
||||
|
||||
System Type:
|
||||
CONFIG_LPC17_UART0=n : Disable UART0 if it is no longer used
|
||||
CONFIG_LPC17_UART1=y : Enable UART1
|
||||
|
||||
Drivers:
|
||||
CONFIG_UART1_SERIAL_CONSOLE=y : Setup up the UART1 configuration
|
||||
CONFIG_UART1_RXBUFSIZE=256
|
||||
CONFIG_UART1_TXBUFSIZE=256
|
||||
CONFIG_UART1_BAUD=115200
|
||||
CONFIG_UART1_BITS=8
|
||||
CONFIG_UART1_PARITY=0
|
||||
CONFIG_UART1_2STOP=0
|
||||
|
||||
In this configuration using UART1, it is necessary to disable LED support
|
||||
on the board. That is because UART1 RXD is set for pin p0.16, but so is
|
||||
LED2. If you do not disable LED support then no incoming serial data will
|
||||
be recevied.
|
||||
|
||||
Common Board Options
|
||||
CONFIG_ARCH_LEDS=n : Disable LED support
|
||||
|
||||
You should also remove the LED2 jumper so that the RXD input does not
|
||||
attempt to drive LED2 as well (However, this does not seem to interfere with
|
||||
data receipt).
|
||||
|
||||
NOTE: If you intend to use LEDs with UART1, then you might want to
|
||||
redesign some ofthe LED logic in the src/ subdirectory so that it does not
|
||||
attempt to use LED2.
|
||||
|
||||
ETHERNET
|
||||
========
|
||||
|
||||
On chip ethernet MAC with external 10/100M PHY DP83848I.
|
||||
The LX_CPU board is populated with integrated connector
|
||||
module (ICM) socket suitable for direct connection to
|
||||
the standard ETHERNET infrastructure.
|
||||
|
||||
Config
|
||||
CONFIG_LPC17_ETHERNET=y
|
||||
CONFIG_LPC17_PHY_AUTONEG=y
|
||||
CONFIG_ETH0_PHY_DP83848C=y
|
||||
|
||||
|
||||
Using OpenOCD with the Olimex ARM-USB-OCD
|
||||
=========================================
|
||||
|
||||
Building OpenOCD under Cygwin:
|
||||
|
||||
Refer to configs/olimex-lpc1766stk/README.txt
|
||||
|
||||
Installing OpenOCD in Ubuntu Linux:
|
||||
|
||||
sudo apt-get install openocd
|
||||
|
||||
Helper Scripts.
|
||||
|
||||
I have been using the Olimex ARM-USB-OCD debugger. OpenOCD
|
||||
requires a configuration file. I keep the one I used last here:
|
||||
|
||||
boards/arm/lpc17xx_40xx/lx_cpu/tools/lx_cpu.cfg
|
||||
|
||||
However, the "correct" configuration script to use with OpenOCD may
|
||||
change as the features of OpenOCD evolve. So you should at least
|
||||
compare that lx_cpu.cfg file with configuration files in
|
||||
/usr/share/openocd/scripts. As of this writing, the configuration
|
||||
files of interest were:
|
||||
|
||||
/usr/local/share/openocd/scripts/interface/openocd-usb.cfg
|
||||
This is the configuration file for the Olimex ARM-USB-OCD
|
||||
debugger. Select a different file if you are using some
|
||||
other debugger supported by OpenOCD.
|
||||
|
||||
/usr/local/share/openocd/scripts/board/?
|
||||
I don't see a board configuration file for the WaveShare
|
||||
LX_CPU board.
|
||||
|
||||
/usr/local/share/openocd/scripts/target/lpc1788.cfg
|
||||
This is the configuration file for the LPC1788 target.
|
||||
It just sets up a few parameters then sources lpc17xx.cfg
|
||||
|
||||
/usr/local/share/openocd/scripts/target/lpc17xx.cfg
|
||||
This is the generic LPC configuration for the LPC17xx
|
||||
family. It is included by lpc1788.cfg.
|
||||
|
||||
NOTE: These files could also be located under /usr/share in some
|
||||
installations. They could be most anywhwere if you are using a
|
||||
windows version of OpenOCD.
|
||||
|
||||
boards/arm/lpc17xx_40xx/lx_cpu/tools/lx_cpu.cfg
|
||||
This is simply openocd-usb.cfg, lpc1788.cfg, and lpc17xx.cfg
|
||||
concatenated into one file for convenience. Don't use it
|
||||
unless you have to.
|
||||
|
||||
There is also a script on the tools/ directory that I use to start
|
||||
the OpenOCD daemon on my system called oocd.sh. That script will
|
||||
probably require some modifications to work in another environment:
|
||||
|
||||
- Possibly the value of OPENOCD_PATH and TARGET_PATH
|
||||
- It assumes that the correct script to use is the one at
|
||||
boards/arm/lpc17xx_40xx/lx_cpu/tools/lx_cpu.cfg
|
||||
|
||||
Starting OpenOCD
|
||||
|
||||
Then you should be able to start the OpenOCD daemon as follows. This
|
||||
assumes that you have already CD'ed to the NuttX build directory:
|
||||
|
||||
. ./setenv.sh
|
||||
oocd.sh $PWD
|
||||
|
||||
The setenv.sh script is a convenience script that you may choose to
|
||||
use or not. It simply sets up the PATH variable so that you can
|
||||
automatically find oocd.sh. You could also do:
|
||||
|
||||
boards/arm/lpc17xx_40xx/lx_cpu/tools/oocd.sh $PWD
|
||||
|
||||
Connecting GDB
|
||||
|
||||
Once the OpenOCD daemon has been started, you can connect to it via
|
||||
GDB using the following GDB command:
|
||||
|
||||
arm-nuttx-elf-gdb
|
||||
(gdb) target remote localhost:3333
|
||||
|
||||
NOTE: The name of your GDB program may differ. For example, with the
|
||||
CodeSourcery toolchain, the ARM GDB would be called arm-none-eabi-gdb.
|
||||
|
||||
OpenOCD will support several special 'monitor' sub-commands. You can
|
||||
use the 'monitor' (or simply 'mon') command to invoke these sub-
|
||||
commands. These GDB commands will send comments to the OpenOCD monitor.
|
||||
Here are a couple that you will need to use:
|
||||
|
||||
(gdb) monitor reset
|
||||
(gdb) monitor halt
|
||||
|
||||
NOTES:
|
||||
|
||||
1. The MCU must be halted using 'monitor halt' prior to loading code.
|
||||
|
||||
2. 'monitor reset' will restart the processor after loading code.
|
||||
|
||||
3. The 'monitor' command can be abbreviated as just 'mon'.
|
||||
|
||||
After starting GDB, you can load the NuttX ELF file like this:
|
||||
|
||||
(gdb) mon halt
|
||||
(gdb) load nuttx
|
||||
|
||||
NOTES:
|
||||
|
||||
1. NuttX should have been built so that it has debugging symbols
|
||||
(by setting CONFIG_DEBUG_SYMBOLS=y in the .config file).
|
||||
|
||||
2. The MCU must be halted prior to loading code.
|
||||
|
||||
3. I find that there are often undetected write failures when using
|
||||
the Olimex ARM-USB-OCD debugber and that if you start the program
|
||||
with a bad FLASH failure, it will lock up OpenOCD. I usually
|
||||
oad nuttx twice, restarting OpenOCD in between in order to assure
|
||||
good FLASH contents:
|
||||
|
||||
(gdb) mon halt
|
||||
(gdb) load nuttx
|
||||
(gdb) mon reset
|
||||
|
||||
Exit GDB, kill the OpenOCD server, recycle power on the board,
|
||||
restart the OpenOCD server and GDB, then:
|
||||
|
||||
(gdb) mon halt
|
||||
(gdb) load nuttx
|
||||
(gdb) mon reset
|
||||
|
||||
Other debuggers may not have these issues and such drastic steps may
|
||||
not be necessary.
|
||||
|
||||
Loading Code with the ISP Board
|
||||
===============================
|
||||
|
||||
Use can also load code onto the board using the WaveShare and the UART0
|
||||
ISP/VCOM board. I use the FlashMagic program for Windows available here:
|
||||
http://www.flashmagictool.com/ . It is so easy to use that no further
|
||||
explanation should be necessary: Just select the LPC1788, the ISP COM
|
||||
port, and the NuttX .hex file and program it.
|
||||
|
||||
CONFIGURATION
|
||||
=============
|
||||
|
||||
nsh
|
||||
---
|
||||
Configures the NuttShell (nsh) located at examples/nsh. The
|
||||
Configuration enables only the serial NSH interface.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configuration using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository./README.txt.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Uses the older, OABI, buildroot toolchain. But that is easily
|
||||
reconfigured:
|
||||
|
||||
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot toolchain
|
||||
CONFIG_ARMV7M_OABI_TOOLCHAIN=y : Older, OABI toolchain
|
||||
|
||||
3. This NSH has support for built-in applications enabled, however,
|
||||
no built-in configurations are built in the defulat configuration.
|
||||
|
||||
4. This configuration has DMA-based SD card support enabled by
|
||||
default. That support can be disabled as follow:
|
||||
|
||||
CONFIG_LPC17_GPDMA=n : No DMA
|
||||
CONFIG_ARCH_DMA=n
|
||||
CONFIG_LPC17_SDCARD=n : No SD card driver
|
||||
CONFIG_SDIO_DMA=n : No SD card DMA
|
||||
CONFIG_MMCSD=n : No MMC/SD driver support
|
||||
CONFIG_FS_FAT=n : No FAT file system support
|
||||
|
||||
5. This configuration has been used for verifying SDRAM by modifying
|
||||
the configuration in the following ways:
|
||||
|
||||
CONFIG_LPC17_EMC=y : Enable the EMC
|
||||
CONFIG_LPC17_EXTDRAM=y : Configure external DRAM
|
||||
CONFIG_LPC17_EXTDRAMSIZE=67108864 : DRAM size 2x256/8 = 64MB
|
||||
CONFIG_SYSTEM_RAMTEST=y : Enable the RAM test built-in
|
||||
|
||||
In this configuration, the SDRAM is not added to heap and so is
|
||||
not excessible to the applications. So the RAM test can be
|
||||
freely executed against the SRAM memory beginning at address
|
||||
0xa000:0000 (CS0).
|
||||
|
||||
6. This configuration has been used for verifying the touchscreen on
|
||||
on the 4.3" LCD module.
|
||||
|
||||
a) As of this writing, this touchscreen is still not functional.
|
||||
Rommel Marcelo has tracked this problem down to noise on the
|
||||
PENIRQ interrupt. There are so many false interrupts that
|
||||
the NuttX interrupt-driven touchscreen driver cannot be used.
|
||||
Other compatible LCDs, however, may not have this issue.
|
||||
|
||||
b) You can enable the touchscreen by modifying the configuration
|
||||
in the following ways:
|
||||
|
||||
Drivers:
|
||||
CONFIG_INPUT=y : Enable support for input devices
|
||||
CONFIG_INPUT_ADS7843E=y : Enable support for the XPT2048
|
||||
CONFIG_ADS7843E_SPIDEV=1 : Use SSP1 for communication
|
||||
CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=n : exchange() method is not supported
|
||||
|
||||
System Type:
|
||||
CONFIG_GPIO_IRQ=y : GPIO interrupt support
|
||||
CONFIG_LPC17_SSP1=y : Enable support for SSP1
|
||||
|
||||
RTOS Features:
|
||||
CONFIG_DISABLE_SIGNALS=n : Signals are required
|
||||
|
||||
Library Support:
|
||||
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
|
||||
|
||||
Applicaton Configuration:
|
||||
CONFIG_EXAMPLES_TOUCHSCREEN=y : Enable the touchscreen built-int test
|
||||
|
||||
Defaults should be okay for related touchscreen settings. Touchscreen
|
||||
debug output can be enabled with:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_DEBUG=y : Enable debug features
|
||||
CONFIG_DEBUG_VERBOSE=y : Enable verbose debug output
|
||||
CONFIG_DEBUG_INPUT=y : Enable debug output from input devices
|
||||
|
||||
c) You will also have to disable SD card support to use this test. The
|
||||
SD card detect (CD) signal is on P0[13]. This signal is shared. It
|
||||
is also used for MOSI1 and USB_UP_LED. The CD pin may be disconnected.
|
||||
There is a jumper on board that enables the CD pin. OR, you can simply
|
||||
remove the SD module so that it does not drive the CD pin.
|
||||
|
||||
Drivers:
|
||||
CONFIG_MMCSD=n : No MMC/SD driver support
|
||||
|
||||
System Type:
|
||||
CONFIG_LPC17_GPDMA=n : No DMA
|
||||
CONFIG_LPC17_SDCARD=n : No SD card driver
|
||||
CONFIG_SDIO_DMA=n : No SD card DMA
|
||||
CONFIG_ARCH_DMA=n
|
||||
|
||||
File Systems:
|
||||
CONFIG_FS_FAT=n : No FAT file system support
|
||||
|
||||
For touchscreen debug output:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_DEBUG=y
|
||||
CONFIG_DEBUG_VERBOSE=y
|
||||
CONFIG_DEBUG_INPUT=y
|
||||
|
||||
7. The button test (apps/examples/buttons) can be built-in by adding
|
||||
the following options. See apps/examples/README.txt for further
|
||||
information about the button test.
|
||||
|
||||
System Type:
|
||||
CONFIG_GPIO_IRQ=y
|
||||
|
||||
Board Selection:
|
||||
CONFIG_ARCH_BUTTONS=y
|
||||
CONFIG_ARCH_IRQBUTTONS=y
|
||||
|
||||
Application Configuration:
|
||||
CONFIG_EXAMPLES_BUTTONS=y
|
||||
CONFIG_EXAMPLES_BUTTONS_MIN=0
|
||||
CONFIG_EXAMPLES_BUTTONS_MAX=7
|
||||
CONFIG_EXAMPLES_IRQBUTTONS_MIN=1
|
||||
CONFIG_EXAMPLES_IRQBUTTONS_MAX=7
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME0="USER1"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME1="USER2"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME2="USER3"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME3="JOYSTICK_A"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME4="JOYSTICK_B"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME5="JOYSTICK_C"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME6="JOYSTICK_D"
|
||||
CONFIG_EXAMPLES_BUTTONS_NAME7="JOYSTICK_CTR"

* user space FLASH partition will be spanned with a single region of size
|
||||
* 2**n bytes. The alignment of the user-space region must be the same. As
|
||||
* a consequence, as the user-space increases in size, the alignmment
|
||||
* requirement also increases.
|
||||
*
|
||||
* This alignment requirement means that the largest user space FLASH region
|
||||
* you can have will be 256KB at it would have to be positioned at
|
||||
* 0x00400000. If you change this address, don't forget to change the
|
||||
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
|
||||
* the check in kernel/userspace.c.
|
||||
*
|
||||
* For the same reasons, the maximum size of the SRAM mapping is limited to
|
||||
* 4KB. Both of these alignment limitations could be reduced by using
|
||||
* multiple regions to map the FLASH/SDRAM range or perhaps with some
|
||||
* clever use of subregions.
|
||||
*
|
||||
* A detailed memory map for the 64KB CPU SRAM region is as follows:
|
||||
*
|
||||
* 0x10000 0000: Kernel .data region. Typical size: 0.1KB
|
||||
* ------- ---- Kernel .bss region. Typical size: 1.8KB
|
||||
* 0x10000 0800: Kernel IDLE thread stack (approximate). Size is
|
||||
* determined by CONFIG_IDLETHREAD_STACKSIZE and
|
||||
* adjustments for alignment. Typical is 1KB.
|
||||
* ------- ---- Padded to 4KB
|
||||
* 0x10000 1000: User .data region. Size is variable.
|
||||
* ------- ---- User .bss region Size is variable.
|
||||
* ------- ---- Beginning of kernel heap. Size determined by
|
||||
* CONFIG_MM_KERNEL_HEAPSIZE.
|
||||
* 0x10000 8000: Beginning of user heap. Can vary with other settings.
|
||||
* 0x10001 0000: End+1 of CPU RAM

* Description:

* Perform application specific initialization. This function is never

* (non-standard) boardctl() interface using the command BOARDIOC_INIT.

*
|

* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initalization logic and the
|
||||
* matching application logic. The value cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

|
||||
* The external functions, lpc17_40_ssp0/1/2select and lpc17_40_ssp0/1/2status
|
||||
* must be provided by board-specific logic. They are implementations of the select
|
||||
* and status methods of the SPI interface defined by struct spi_ops_s (see
|
||||
* include/nuttx/spi/spi.h). All other methods (including lpc17_40_sspbus_initialize())
|
||||
* are provided by common LPC17xx logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in lpc17_40_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide lpc17_40_ssp0/1/2select() and lpc17_40_ssp0/1/2status() functions
|
||||
* in your board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is configured.
|
||||
* 3. Add a calls to lpc17_40_sspbus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by lpc17_40_sspbus_initialize() may then be used to bind the
|
||||
* SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
