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

First of all ,boot os (ubuntu)from emmc, then erase like this :
  1. 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 .
