Hello everyone, please tell me what is the problem? I can’t start Rock Pi 5, I recorded microSD cards from under Linux and Windows, the result is the same. Used different memory cards. If there is a card, the following message in the console:
DDR Version V1.08 20220617
unknown device
error
ERR
model information: Rock 5B V1.42.2022.08.29
Sorry about the bad experience.
This appears to be a hardware issue, please contact the seller you purchased from to get a replacement.
When we get this board, we’ll analyze why it failed.
