Failed to init SD card (Picofly)

[MethodMan2025]

Hi guys,
I have installed the Picofly RP2040 mod on my OLED Switch. Everything worked so far. I got the Picofly No SD Card image. I then loaded the necessary files onto my 512 GB Sandisk Ultra MicoSD card and was able to start hekate. I created a file based emuMMC in hekate. Everything worked a couple of hours but now the SD Card is not recognized anymore.
The picofly image at start says "Failed to init SD card". If I boot to the stock firmware, I got the Error code: 2016-0641.
What could be wrong?

Thank you for taking time to read my post. I look forward to your response.

return or replace your SD card

The SD card was not recognized because the connection of the board was loose. The microSD Card is recognized now, but a lot of warnings appear like eMMC slow Mod in Benchmark and "Nyx exception occurred" errors. I couldn't create an emuMMC because of the errors.
Instead of my 512GB Sandisk Micro SD, I put a very old 8GB Kingston MicroSD and now the eMMC Benchmark runs without problems. No more slow eMMC warnings and no freezing so far. It seems to work with a 8GB Kingston MicroSD but not with a 512GB Sandisk Ultra.
Wtf is that normal?

Bad solder. Or add more 2 resistor dat0 and cmd on pico or long wiers...

Thank you guys, but my Switch is completely dead now. It won't even start without the Picofly board. Something is wrong with the emmc.
I have opened a new thread for this.

I appreciate every help.
