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
