Unable to run built Linux images

irenek

I just got my ROC-RK3328-CC board.  Trying to build a Linux image for it using instructions at this link:

http://wiki.t-firefly.com/ROC-RK3328-CC/linux_compile.html

After following all steps, flashed the image on SD card using the following command:

sudo dd if=rockdev/pack/ROC-RK3328-CC-BUILDROOT-GPT-20200908-1351.img of=/dev/sdc  conv=notrunc

But, the image doesn't boot.  I don't have the serial port connection working yet, but I don't see anything from the HDMI port that's connected to a monitor.  I also tried the Ubuntu build and that image doesn't boot either.  I am able to flash the prebuilt image from http://share.loverpi.com/board/l ... 28-cc/image/ubuntu/ and that comes up fine.  But, the images that I build don't seem to do anything.  Any suggestions?

Just want to add that it appears that .img files that are created during the build don't seem to be in correct format.  The pre-built image that I downloaded, I am able to open with 7-zip as an archive, but I am unable to do that with the images that I built.

Hey! I'm having similar issues with building from source on my ROC-RK3328-CC. Double-check your device tree configuration; incorrect settings often lead to no boot. Could it be the device tree? Also, I've spent hours playing Block Blast while debugging these issues lol.
