some error about esp32 for sd driver
Re: some error about esp32 for sd driver
According to the log, you do something about GPIO4 pin (reconfigure it as input) after SD card is initialized.
This is an SD card pin, and changing its configuration causes SD card to fail.

Check your setting of io_conf.pin_bit_mask in spi_master2.c. You put a GPIO number in there (18), but you should put a bitmask in there (1<<18).
