My Miata engine exploded the other week so I bought a MicroRusEFI for a different project.
I received a preassembled Microrusefi the other day and I attempted to flash the firmware on my Linux desktop, but it looks like this board doesn't work.
I plugged it in to my computer holding PROGRAM to boot into DFU. Upon connecting, lsusb does not show microrusefi.
So I thought this may be a driver issue. In order to investigate further, I reconnected it to my computer and ran dmesg. Dmesg shows NO evidence my computer had a USB device plugged into it. I tried 3 different USB cables with no results. I retried without booting into DFU, and I get the same result. I also tried 2 different Windows computers and I can't get the device to show up on any of them.
All LEDs on the board are blinking as intended. Attached is the output of dmesg, and the board in DFU as well as regular mode. I've not modified the board in any way or even plugged in my connector.
Upon request, I also made an attempt to communicate with the board in non-DFU mode. So I plugged in the board into my PC NOT holding program as normal and did dmesg. This time it looks like Linux attempted to communicate with the board but failed. lsusb shows nothing. I also tried this with several different USB cables, still no change.
This was the output:
