Any way to "timeout" esp32 when in DOWNLOAD_BOOT (waiting for download) mode?

[ReinierH]

Hi All,

We use the ESP32 all our products. Unfortunately, due too a design flaw in one of our pcb's the ESP32 sometimes boots into "DOWNLOAD_BOOT" mode. (GPIO0 gets pulled down).

In this case the only way to get it back to normal execution mode is by powercycling the ESP32. are there any other ways to get it out of "DOWNLOAD_BOOT" mode?

Isn't there any timeout in the "DOWNLOAD_BOOT" mode?

Regards,

Reinier

Hi Reinier,

No timeout, I'm afraid. In other boot modes there is a Watchdog Timer running but not in download mode.

The only other way to reset would be to connect via serial and trigger a system reset. But I expect this is not useful for you.

Sorry,


Angus
