I connected my esp32-c3 module with my stm32 microcontroller via UART. My question is can I flash or upload my firmware through UART not USB because I already have USB for stm32 and it would be better if I can use just one USB for both stm32 and esp32.
Esp32-c3 is only used for wifi and bluetooth communication, I don't need for others GPIO pins to function.

Re: Flashing Firmware via microcontroller and UART.
Yes, you can. Either program the STM as a passthrough device (so anything on the PC can talk to the ESP directly) or you can use esp-serial-flasher.
