[charleshuang]

Hi

I'm using iMX8mq evk board with Yocto 3.0 (5.4.70)

I want to run M4 helloworld demo .

Command as below:

--------------------------------------------------------------------------

u-boot=> fatload mmc 1:1 0x48000000 imx8mq_m4_TCM_hello_world.bin

6512 bytes read in 19 ms (334 KiB/s)

u-boot=> cp.b 0x48000000 0x7e0000 20000

u-boot=> dcache flush

u-boot=> bootaux 0x7e0000

## Starting auxiliary core stack = 0x20020000, pc = 0x1FFE0305...

u-boot=>

--------------------------------------------------------------------------

I want to know if there is any problem with the Bold string
