I’ve found the parabola image I used back in 2021, and tried to boot it on an EOMA card revision 2.7.4 and a microdesktop revision 1.7

In the process of attaching peripheries, I must have blown something on the microdesktop, the power LED no longer lights up, tested multiple chargers. I’m fairly certain that the LED did light up green when I started working on the board today. Is it possible that I blew a fuse somewhere?

Apart from that, I currently can’t get the system to boot. I have output from the boot loader, but it’s not much:

U-Boot SPL 2017.01-2 (Jan 18 2017 - 21:30:38)
DRAM: 2048 MiB
CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
Trying to boot from MMC2MMC Device 1 not found
spl: could not find mmc device. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

This is when I insert the sd card in the EOMA card directly. When I insert the sd card into the microdesktop, I don’t get anything. Still working on it though.

I’m confident that this is salvageable, considering that I do get boot loader output through UART. I’ll keep looking into it. If you have any hints, I’d appreciate it.

in the meantime, I’ll prepare a magnet link / http direct download for the image I’m using, in case it’s useful for someone else. I’ll send those links to the list ASAP.

Best, 
Andreas
