An error occurs when using rp2040 zero "*== No eMMC CMD1 request (poor wiring, or dead CPU)", OFW is loading. But if I solder the old hwfly, then everything works fine. I've tried different rp2040 zero, all works in other Nintendo Switch
Suddenly there was a short circuit on the vdd emmc line. I removed the emmc, the capacitors nearby, as well as the m92t36, but nothing has changed, where could the problem be?
