I'm using a ESP32 with version 0.4 for esp-hosted SDIO I'm using raspberry 4 model B with kernel 5.10 and 5.15 and both of them doesn't work due to the error below

Can you confirm which ESP board you are using? This issue occurs either due to absence of required pull-ups on SDIO lines or bad jumper wires.

The kit is ESP32 DEV KIT C V4, I add the 10k pull up resistor on all lines but not on IO12/DATA2 because the pin in a bootstrap pin.
