esp32 stuck after 4 successive http-ota

Postby ventureg » Tue May 19, 2020 7:34 am


we are using esp-wroom module in our project. and got stuck while using http-ota.
I can reproduce the problem, but no clue about how to fix it.

Steps to reproduce the problem:
1 make flash to burn the firmware to OTA_0 partition.
2 using http-wifi to OTA the firmware, OTA_0->OTA_1->OTA_0->OTA_1
3 then esp32 got stuck, no more print

here I can use [make monitor] to reset esp32, and from debug info from uart , the last OTA fails.

And I use watchdog to monitor the http-ota process, the watchdog will bite after 60 seconds. But no luck, the esp32 still stuck.

using esptool to retrive chip info:
Chip is ESP32D0WDQ5 (revision (unknown 0xa))

And the partition table is as follows:
# Espressif ESP32 Partition Table
# Name, Type, SubType, Offset, Size, Flags

Any news on the issue? Got it solved?
When did the ESP got stuck, during the download, upgrade or reboot after upgrade?
