boards/arm: add support for imx95-evk m7 core
- Add support for the IMX95LPD5EVK-19 evaluation kit (M7 core only)
- Firmware can be executed from ITCM, DDR or NOR flash
- configurations:
'nsh' A minimal configuration that only enables nsh shell
on a UART
'rpmsg' This configuration is similar to nsh but in addition
it offers the Remote Processing Messaging (RPMsg) service to
enable heterogeneous inter-core communication.

IMX95LPD5EVK-19
|
||||||
|
===============
|
||||||
|
|
||||||
|
The IMX95LPD5EVK-19 board is a platform designed to show the most commonly
|
||||||
|
used features of the i.MX 95 automotive applications processor.
|
||||||
|
|
||||||
|
Features
|
||||||
|
========
|
||||||
|
|
||||||
|
- Multicore Processing [1]_
|
||||||
|
- 1x Arm Cortex-M7
|
||||||
|
- 6x Arm Cortex-A55 multicore complex
|
||||||
|
- 1x Arm Cortex-M33
|
||||||
|
- Memory
|
||||||
|
- On-Chip Memory
|
||||||
|
- 1376kB SRAM (ECC)
|
||||||
|
- External Memory
|
||||||
|
- Up to 6.4GT/s x32 LPDDR5/LPDDR4X (with Inline ECC & Inline Encrpytion)
|
||||||
|
- 1x Octal SPI, including support for SPI NOR and SPI NAND memories
|
||||||
|
- Connectivity
|
||||||
|
- CAN FD
|
||||||
|
- UART/USART/Profibus, I²C, SPI
|
||||||
|
- Messaging Units (MU) to support IPC between heterogeneous cores
|
||||||
|
|
||||||
|
.. [1] NuttX is currently supported exclusively on the Cortex-M7 core of the
|
||||||
|
i.MX95
|
||||||
|
|
||||||
|
Serial Console
|
||||||
|
==============
|
||||||
|
|
||||||
|
The IMX95LPD5EVK-19 board features a high-speed USB-to-UART/MPSSE device,
|
||||||
|
FT4232H (U70) that provides a debug interface for the i.MX95 processor through
|
||||||
|
the USB type-C connector (J31). The device acts as a bridge to enable
|
||||||
|
communication between the target processor and the host computer, which
|
||||||
|
connects to the USB connector (J31) through a USB cable.
|
||||||
|
|
||||||
|
Channel A is used as UART port to provide USB-to-UART option for debugging the
|
||||||
|
Arm Cortex-M7 core of the i.MX 95 processor (default option).
|
||||||
|
|
||||||
|
J-Link External Debug Probe
|
||||||
|
===========================
|
||||||
|
|
||||||
|
The IMX95LPD5EVK-19 board provides a 2x5-pin Samtec FTSH-105-01-L-DV-K header
|
||||||
|
(J30) for connecting a JTAG debugger (external JTAG) for debugging the i.MX95
|
||||||
|
processor. The FT4234H JTAG provides the remote debug option for the i.MX95
|
||||||
|
processor.
|
||||||
|
|
||||||
|
Configurations
|
||||||
|
==============
|
||||||
|
|
||||||
|
nsh
|
||||||
|
---
|
||||||
|
|
||||||
|
Configures the NuttShell (nsh) located at examples/nsh. This NSH
|
||||||
|
configuration is focused on low level, command-line driver testing. Built-in
|
||||||
|
applications are supported, but none are enabled. This configuration does not
|
||||||
|
support a network.
|
||||||
|
|
||||||
|
This configuration can be used in combination with the default sd-card image
|
||||||
|
that is shipped with the EVK.
|
||||||
|
|
||||||
|
rpmsg
|
||||||
|
-----
|
||||||
|
|
||||||
|
This configuration is similar to nsh but in addition it offers the Remote
|
||||||
|
Processing Messaging (RPMsg) service to enable heterogeneous inter-core
|
||||||
|
communication. A virtual UART (CONFIG_RPMSG_UART) is made available on which
|
||||||
|
an OS running on the A55 cores can connect. There is also an option to use
|
||||||
|
the filesystem client feature in which a remote directory can be mounted to
|
||||||
|
a local directory (CONFIG_FS_RPMSGFS).
|
||||||
|
|
||||||
|
The rpmsg configuration executes the code from DDR since its code memory
|
||||||
|
footprint is bigger than the ITCM size. In the case of using the default
|
||||||
|
sd-card image from the EVK, adaptations are needed on the software running on
|
||||||
|
the M33 and A55 cores.
|
||||||
|
|
||||||
|
- `System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
|
||||||
|
the M7 access to the DDR region
|
||||||
|
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) should reserve
|
||||||
|
the DDR region by specifying it in the device tree so linux won't make
|
||||||
|
use of it
|
||||||
|
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) needs the
|
||||||
|
NuttX compatible rpmsg_tty and rpmsg_fs drivers. See `dev mailing list
|
||||||
|
<https://www.mail-archive.com/dev@nuttx.apache.org/msg12112.html>`_

*
|

|
* 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 initialization logic and the
|
||||||
|
* matching application logic. The value could 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.

* Name: imx95_lpspixcmddata

|

|
* Description:
|

|
* Some devices require an additional out-of-band bit to specify if the

* example, in "9-bit" displays where the 9th bit is the CMD/DATA bit.
|
||||||
|
* This function provides selection of command or data.
|
||||||
|
*
|
||||||
|
* This "latches" the CMD/DATA state. It does not have to be called before
|
||||||
|
* every word is transferred; only when the CMD/DATA state changes. This
|

|
* method is required if CONFIG_SPI_CMDDATA is selected in the NuttX

* configuration
|

|
*
|

* Input Parameters:
|

|
* dev - Device-specific state data
|

|
* cmd - TRUE: The following word is a command; FALSE: the following words
|
||||||
|
* are data.

*

* Returned Value:

* OK unless an error occurs. Then a negated errno value is returned
