Hacking Hardware McFly - an RP2040 board compatible with Picofly

[ypeeLs]

Aight, we're done. My Switch is now modded and will live a happy life as a linux tablet for networking stuff. There is one issue tho: If I boot the system up and then shut it down, it won't boot up again unless I disconnect the battery. Any ideas on how to potentially fix this? (Samsung eMMC btw)

If any other info is needed, hit me up.

have you tried pressing the power button for 20 seconds?

Yes, nothing chnaged. System still refuses to start after the first successful boot and shutdown.

Could an imperfect CPU Flex cable install cause this bug?

Personally I'd check soldering... Perhaps a reset line issue or a 3v3 line issue. Make sure that it's a good connection, that all flux has been cleaned (IPA) and there's no shorts.

FYI/FWIW & for those that have been following my posts...
I've created a related thread for my fly2040 variant - as it has slightly modified firmware and has Atmosphere support (sysmodule & homebrew app).
Thought I'd share here as it's picofly based and picofly compatible (with extras).
