Needing to remove/insert sdcard before I can open it

[nebogeo]

I am not sure if this is an issue with this library (I'm using the 0.8.1 version of the embedded-sdmmc crate) but I'm having an issue where everything works fine - but only if I remove and insert an sdcard after booting (I'm using a Raspberry Pi Pico with PiCowbell Adalogger).

Where should I be looking to solve this issue? I've tried messing around with mark_card_uninit() but no joy.

I would start with putting a logic analyser on the bus and capturing all the traffic, ideally along with an analog capture of the SD card power rail.

A defmt trace from the library would also help.

Good advice, thanks - I only have a 2 channel handheld oscilloscope, but I can at least record what's happening.

I'll also try the Adafruit micropython version and do this same (I should have tried that before posting really).

I'll compare and report back.
