esputil flash 0 frimware.bin hang #6

Open borisnimcevic opened 1 year ago

borisnimcevic commented 1 year ago

Hi, I am trying the example/blinky and it seems that it builds with no problem but then it stops after "esputil flash 0 firmware.bin" and hangs there forever.

firmware.bin is generated with no issues

I tried on two different esp32c3 boards, but the same result. So I am stuck with ideas on what to do next.

What is it waiting for when it is trying to flash the chip? Where could be my next step in debugging this?

Thank you.

Try in verbose mode.

To compare, here's my output with the blinky example:

I've encountered the same problem. Verbose mode shows nothing — before any if (verbose) the program hangs on open syscall in open_serial function. As far as I could check with fuser and lsof, the device file is free.

I'm using macOS 14.1.1 on MacBook Air M1 and ESP32C3 board by LuatOS . ESP IDF compiles and flashes the board without problems.
