        Hey @Tchill73 if you want to use the stock firmware you can use the m5burner tool https://m5stack.com/pages/download if you have your own firmware its better to use esptool

          Hello @Tchill73, please post the Arduino error message. I used m5stack cam with ESP-IDF and it worked fine.

            Hello, tank you for your reply.

            I tried with the firmeware for the camera F but it does not work.
            M5camera V1.0.0
            error :
            17:37:46.943 -> E (90518) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
            17:37:46.943 -> E (90518) task_wdt: - IDLE0 (CPU 0)

            17:37:46.943 -> E (90518) task_wdt: CPU 1: IDLE1

            I try with ESP-IDF (Windows 10)
            5stack-cam-psram-master\m5stack-cam-psram-master\wifi\wifi_sta\firmware\Camera F
            I am sure there is not much missing

            The error is :
