ESP_HTTPS_OTA failing on large bin files

[QuentinB]

Okay, so I have an interesting issue here.

I'm running on Mac OSX 10.14.5 with the ESP32_DevKitC.

I'm just using the ota_example at this point. I've tried and succeeded in flashing the hello_world.bin from the idf examples, but when I try a .bin of the project I'm working on (~1.2MB) the process will start flashing and I'll see successful HTTP transfers, but eventually fail with the following output:

Code: Select all

E (101207) esp_image: invalid segment length 0x456d3133
E (101207) esp_https_ota: Error: esp_ota_write failed! err=0x0
E (101207) simple_ota_example: Firmware upgrade failed

I piped all debug output into a .log file, which I've attached, as its quite long.

Attempts to fix/workaround:

• Re-built app, after manually checking it flashes normally
• Imaged .bin file onto device using otatool.py successfully
• switched from openssl-based dummy server to python-based server

Hello,

Would you please let me know that are you using custom partition table or default partition table for OTA?

because you image size is higher then 1 MB and at that time you need to use custom partition to keep OTA partition for 1.5 or 2 MB as per your OTA size.

As Ritesh pointed out, your partition table (from log you shared) is allocating 1M for `ota_x` partitions, you will need to customize partition table and allocate little larger space (per your upgrade binary requirement), that should help to fix the problem.

Thanks.

Exactly like that.
