How to disable M4 core in IMX8MMEVK project? If i wanna use the debug serial port UART4 of M4 as the general serial port of A53, what modifications need to be made in terms of software and hardware?
Can anyone give me some advice?
refer to the schematic, uart4 is for M4 debug, you can assign uart4 to A53 domain, you can refer to the function "_early_platform_setup2" in the imx8mm_bl31_setup.c,
I had Same question but need to elobrate it more. Thanks McDVoice @nick lau
