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.
Could you please clarify your setup. Is this sunxi-u-boot (legacy u-boot) via fel or written to the sd card?
Are there changes software or hardwire wise? I don't understand why it worked 2021 and fails to boot now.
