Thank you Sprite for the support!
As you told me: PIN 19 and PIN 22 were not configured as GPIO
In fact SDIO Pin Mapping on ESP32-C6
The SDIO interface uses specific GPIO pins:
GPIO18: SDIO_CMD (Command line)
GPIO19: SDIO_CLK (Clock line)
GPIO20: SDIO_DATA0 (Data line 0)
GPIO21: SDIO_DATA1 (Data ...

Set outputs with AT commands
I'm trying to drive high the GPIO 19 and 22 PINs on the ESP-C6-MINI-1U module.
I'm doing it with AT+SYSREG because I have 3250 modules with AT V4.0.0 firmware .
The sequence I'm doing is this:
AT+RESTORE
OK
AT+SYSREG=1,0x600B4928,0x00001200 //MUX SET GPIO19
OK
AT+SYSREG=0,0x600B4928 //Read if the ...
