Cortex-M4 on iMX6sx - Custom board

sFurter — Tue, 21 Jan 2025 14:48:47 GMT

I'm trying to use the Cortex-M4 core on the iMX6sx on our customized board.

I tried to integrate the imx6sx-sdb-m4.dts into our device tree, but linux does not manage to start properly.

Is there a guide how to setup the device tree properly to configure the M4 core?

Regards,

Sandro

I hope you are doing very well.

Please refer to the imx6sx-sdb-m4.dts.

You can take it as example.

Best regards,

Salas.

Thanks I'm doing good, I hope you too?

Yes I took imxsx-sdb-m4.dts as a reference.

I found this guide to start the M4 core from U-Boot (Hello World Application).

But I have no output on the console UART2 and when I proceed booting to Linux (with the modified dtb) it does not run properly.

Am I missing something (obviously yes )
