Hey guys!
Tested the board with SD card, it worked. Tried eMMC it worked, like one time. After that the board no longer wants to boot on SD card or eMMC.
The board still negotiate power delivery, it is still posible to shut the board down by long pressing the power button and you can start it again by clicking the start button.
Only the great light comes on, not the blue.
No network activity and it does not initate any usb devices.
The power draw is always fixed at 2.75W and the rk3588s chip heats up, no other parts of the board gets noticeably warm.
The eMMC module I was using is a 16GB module ordered togheter with the Rock 5A from ALLNET China. Lettering on the eMMC is SEC313 B041 KLMAG1JETD NUD77SHRS
SD card om using is a Sandisk Ultra plus 128GB.
Tried re flashing both the SD and eMMC multiple times but no luck.
Power draw is the same no matter if the SD card or eMMC or non of them installed. Eth, or usb devices don’t change the power draw.
Having the SPIFlash eMMC installed or not with or without the SD card does not change anything.
No output on HDMI.
Any ideas on what could be wrong?
Thanks!
