ethernet OTA ERROR when the image size larger than hollo-word.bin

[harry_wei]

Hi

I added OTA features to my esp32 project and have a problems(My hardware is ESP32-Ethernet-Kit_A_V1.1(ESP32-WROVER-B + IP101), and my IDF version is ESP-IDF v4.0-beta1-180-ga21eb04cc.I have installed the Ethernet driver correctly and got the local IP (DHCP succeeded)):

When I use Hello word.bin (file size is 150kb), I can successfully implement OTA(Almost every test was a success), however when I use my own project's .bin file (file size is 1.2MB), OTA always failed and always return the errors :

Same hardware, same server, different image file sizes,the small image can succeed, but the larger image is not successful, so I guess this is not the HTTP server fault, but the defect of ESP IDF.
so I guess the problem is your esp-idf's bug:when the firmware image size is larger, the lower the success rate or OTA.

I'd like to know if you have tested the OTA when the firmware size is larger than hello word.bin (for example, the image size is larger than 1.5 MB).In particular, have you tested the OTA situation when using ip101(ethernet mode) for network communication?

Best Wishes!

HI,

I have solved this problem. There should be a problem with the default settings of ESP IDF.

Thanks！
