Running M4 demo application on i.MX8
confirm imx8mq_m4_TCM_hello_world.bin in partition 1
connect mcu debug port
u-boot command as below:
boot from emmc
fatload mmc 0:1 0x7e0000 imx8mq_m4_TCM_hello_world.bin
boot from sd
fatload mmc 1:1 0x7e0000 imx8mq_m4_TCM_hello_world.bin
then
bootaux 0x7e0000
console will show "hello world"
