I've upgraded my RB433AH with latest RtOS and latest firmware 3,24.
Decided to add a 1GB micro SD card for a backups/files.
After the first boot the card was not recognized, after the second boot the device is making a one time crackling sound, instead of the normal beep.
Removed the micro SD card and now there's a bootloop with this same crackling sound. The boot procedure is looping without being able to finish (two beeps).
Also the board won't boot at all if there aren't any miniPCI cards installed in at least one of the 3 slots.
Tomorrow I'll try to revive the board with serial cable and netinstall.
The micro SD card is working fine in the card reader of my laptop. I also formatted the card in the reader.
What could be the reason?
Is the board's hardware failed, or it could be a software issue?
Thanks in advance.
