ESP32 OTA
Posted: Thu Jun 13, 2024 4:00 pm
I implemented the ability to do Firmware OTA using esp_https_ota using the code below.
The problem is that once it starts writing to flash, I'm getting a TG0WDT_SYS_RST. Sometimes the write to the flash just seems to hang after some writes.
I don't know what's wrong and how to debug it.
Do I pet this watchdog during the download? I have a callback with ESP_HTTPS_OTA_WRITE_FLASH that I could use, but haven't found out how to pet the watchdog properly.
