Hi zhoupeng,
We need more details to be able to help you with this issue.
What version of ESP-IDF are you using?
If you run "esptool.py --chip esp32 image_info my_ota.bin", does the output say that the hash is correct?
Have you verified the received image length is correct?
Have you checked all of the esp_ota_xxx functions return without errors?

I have a similar problem. Getting following error.
Code: Select all
[0;31mE (298214) esp_image: Image hash failed - image is corrupt[0m
[0;31mE (298784) esp_image: Checksum failed. Calculated 0x10 read 0x18[0m
Additional details:
- Apart from OTA, other two taks are running but they are suspended before starting OTA
- BLE is running.
I am guessing following threads explain the issue
The problem is .
- There are many devices in the field but OTA is failing only on few devices
- The suggestions mentioned above threads may fix the issue. But I can't do those changes for the devices in the field
esp-idf: v3.1
Attaching the custom partition format and sdkconfig used.
