imx8mq load fimware to m4 from linux

Hi.

I am trying to use the M4 core from linux in an IMX8MQ processor.

I tried the m4fwloader but it says: "Board is not supported.".

Then I tried m4ctrl, but after the "insmod m4ctrl_dev.ko" step, I am getting: "Cannot obtain MU ID"

I did a little search in the source code and I found that the imx8_mu_init function searches for "fsl,imx8-mu" which only exists in imx8qx dts files.

So does anybody know if the m4ctrl utility supports imx8mq?

If not is there any other alternative tools or methods to load application in the m4 core from linux?

Best Regards,

Giannis

Hi Giannis,

have you found a solution to this problem? I'm also trying to update the M4 of an i.MX8MQ from Yocto.

Hello Ioannis Gragopoulos,

The MCU Xpresso SDK for i.MX8MQ EVK contains examples and documentation regarding Cortex-M4 firmware deployment. You can generate and download it using the following website:

   MCUXpresso SDK Builder

You can also take a look to the Getting Started with MCUXpresso SDK for EVK-MIMX8MQ (included in SDK documentation) attached below. It states that two building and development toolchains are supported:

  •  Arm GCC + SEGGER J-Link GDB Server. This is a command line tool option and it supports both Windows® OS and Linux® OS.
  •  IAR Embedded Workbench® for Arm and SEGGER J-Link software

 

I hope this helps!

Regards,
