Hash verification fails when I use ota feature， I need the bin file format。

[zhoupeng]

Code: Select all

D (12931) esp_image: Calculated hash: a4937099[0m
[0;31mE (12941) esp_image: Image hash failed - image is corrupt[0m
D (12941) esp_image: Expected hash: 2ddc33a7

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

• https://github.com/espressif/esp-idf/issues/4120
• https://github.com/espressif/esp-idf/issues/2068

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.
