Yocto SD card Image

socfpga · Posted at 5/16/2017 20:32:47

Hi,

I have followed the instructions on building meta-rockchip layer to build an SD card image.

But I cant seem to boot from it. I have flashed the SD card image,
rk-image-multimedia-firefly-rk3399-20170511220643-gpt.img

And inserted the SD card and it doesnt seem to boot. Any reason what I am missing?

Warm Regards
Kumar

Thanks Isle!

How do I do it? I cant seem to stop at u-boot? Is there anyway to erase eMMC?

First of all ,boot os (ubuntu)from emmc, then erase like this :

dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=4

Copy the code

Tips:
the cpu will load from emmc before from SD card, but if there is no code in the emmc ,it will load from SD card .
