Hi, how do I write ESP32-C3 eFuse bits? Can it be done through some ESPhome code or is there a tool for it?
I’m working on replacing some Tuya CB3S and Zigbee modules with ESP8685-WROOM-04 modules in a mini 1/2/3ch switch modules. It work’s nicely, but there is one problem though. GPIO6 is used for switching relay through a mosfet transistor. Unfortunately this pin is by default used as JTAG/MTCK pin where pullup resistor is enabled. This cause that the relay is switched on shortly when powering on the module.
The JTAG feature can be disabled by setting DIS_PAD_JTAG bit to 1, which cause the GPIO6 is high-impedance input. This needs to be done only once and cannot be reverted. Any idea how to do it?
EDIT: I found out there is a esptool.py from Espressif, which contains espefuse.py that seems to be the tool for reading/writing efuse bits.
