Hello sir,
Customer uses fsl-imx8mm-evk-m4.dtb to run the RPMsg. but the Camera can't work with the m4.dtb.
In the fsl-imx8mm-evk-m4.dts, there is comment mentions that some IPs was disable because maybe used by M4.
Is there any user guide can help customer to configure the Cortex-A device tree that maybe some peripherials are dedicated for Cortex-M4 or other? Thanks.
Regards,
Daniel

Hi Igorpadykov,
Thank you for your information,
customer makes their own i.MX8MM SoM board that use same UART1 for Cypress-CYW43455 (WiFI/BT).
the CYW43455 also not work with fsl-imx8mm-evk-m4.dtb. but the UART1 does not be disable in the fsl-imx8mm-evk-m4.dts. Is anything we need to check? Thanks.

Hi Igorpadykov,
It seems they are different. the BT uses UART1 not UART4.
BTW,
Is there any IP used when run RPMsg? Thanks.
