processor.
Firmware location
=================
Instruction Tightly Coupled Memory (ITCM)
-----------------------------------------
The purpose of the Tightly-Coupled Memory (TCM) is to provide low-latency
memory that the processor can use without the unpredictability that is a
feature of caches. By default the firmware will be located in this area
(256K).
DDR
---
DDR memory can be used in case the code memory footprint becomes bigger than
the ITCM size. Using this configuration implies that other cores should be
aware of this.
For the default sd-card image from the EVK, these 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

Configures the NuttShell (nsh) and also adds CAN support. CAN1 is enabled and
can be accessed at J17 on the EVK. Make sure that SW9[3] (PDM_CAN_SEL) is set
to ON. The configuration includes CAN utilities as candump and cansend.

`System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
the M7 access rights to the PIN_PDM_CLK (CAN1_TX) and
PIN_PDM_BIT_STREAM0 (CAN1_RX) pins in the mx95evk.cfg.
Alternatively these can be set manually in the system manager's console:
