Install ubuntu via SD card

if you want to update the firmware you just need to format your SD card ( i formatted it as exfat) before selecting the upgrade firmware option. It should complete without giving an error.

I can confirm this. 1.53 does show the SD card, but will complain "Opening firmware failed’.
All other more recent versions will not show the SD card at all. Running as administrator doesn’t solve the issue.

Edit: I’ve now used “./upgrade_tool uf my_image.img” to load the firmware on Linux. but it also says “Note: invalid tag of firmware, please check firmware.”

So probably that’s why it said “Opening firmware failed” on windows and my custom image is just bad.

Nevertheless 1.53 seems to be the only version which recognizes an sd card on windows 11.
