How to boot with yocto image

#1

Hi everyone,

Now I can build the image with yocto.
I followed the wiki, and clone zeus branch.

Now I got the radxa-console-image-rockpi-4c-rk3399-gpt.img.
I use the dd command to burn image to SD card.

I’d like to use uart, but I got the messages.
channel 0 training pass!
channel 1 training pass!
change freq to 800MHz 1,0
Channel 0: LPDDR4,800MHz
Bus Width=32 Col=10 Bank=8 Row=15/15 CS=2 Die Bus-Width=16

Channel 1: LPDDR4,800MHz

256B stride
ch 0 ddrconfig = 0x101, ddrsize = 0x2020
ch 1 ddrconfig = 0x101, ddrsize = 0x2020
pmugrf_os_reg[2] = 0x3AA1FAA1, stride = 0xD
OUT

How to fix it?
I can not boot with SD card.

Thanks

Hi. Can you use this yocto image on ROCK Pi 4C first? https://dl.radxa.com/rockpi4/images/yocto/radxa-console-image-rockpi-4c-rk3399-gpt.img.gz

Hi Stephen,

This is my mistake.
I inserted type c cable into usb hub.
Now, I use the adapter and it works.

Thank you for your reply.

Thanks,
Jonas
