Undesired enter serial bootloader
Posted: Sat Nov 05, 2022 4:49 pm
Hello,
I'm developing a project with (sometimes) unstable power as requirement with esp32-c3-mini soc. I've placed RC circuit as datasheet says on enable pin but I still face undesired enter on serial bootloader when several resets ocurr in short period of time. I'm considering adding an external watchdog circuit to supervise this state, but...
Is there anyway to do it without an external circuit? Can I disable serial bootloader and program only though OTA? Or, Can I use watchdog in serial bootloader to reset if serial transmision does not ocur in some time? Or maybe using secure boot?
Thanks in advance
