WebUpdate how to create firmware image file?

[warwound]

I have flashed the WebUpdate example to my WT32-ETH01.
But am confused - how do I create the firmware image file that I will upload?

In Arduino IDE I tried Sketch menu > Export Compiled Binary.
In my sketch folder I see:
/build/esp32.esp32.wt32-eth01/
which contains files:
ConnectBox2.ino.bin
ConnectBox2.ino.bootloader.bin
ConnectBox2.ino.elf
ConnectBox2.ino.map
ConnectBox2.ino.merged.bin
ConnectBox2.ino.partitions.bin

I tried uploading the file ConnectBox2.ino.bin but my wt32 crashed:

abort() was called at PC 0x40081c99 on core 1

I don't understand any of the decoded exception.

Can anyone tell me how to create the required firmware image file?

It looks to me like it is having trouble erasing the flash to lay down the new firmware. This can be due to a hardware error on the flash, but more likely there is a mismatch between the partitioning originally laid down on the hardware and what you are trying to upload. Make sure you use the exact same board options (especially partition scheme) when you build your new firmware.
I may be a bit biased, but I think the OTAWebUpdater example does a better job, particularly that it checks that the firmware uploaded will fit in the OTA partition size.

I have now modified the OTAWebUpdater to work in my sketch but it it fails much like the WebUpdate.
I suspect I'm not uploading the correct firmware image - the original topic of this post.

In Arduino IDE I tried Sketch menu > Export Compiled Binary.
In my sketch folder I see 3 binary files:
/build/esp32.esp32.wt32-eth01/
which contains files:
ConnectBox2.ino.bin, 1.1MB
ConnectBox2.ino.bootloader.bin, 24KB
ConnectBox2.ino.partitions.bin, 3KB

My partition scheme is:
Minimal (1.3MB APP / 700KB SPIFFS)

When I compile my sketch the output states:

Sketch uses 1115949 bytes (13%) of program storage space. Maximum is 8388608 bytes.

So I've assumed the 1.1MB file ConnectBox2.ino.bin is the corretc firmware image.

Any ideas?

Do a simple test. Build the example and upload it. Change some of the text in the html page so you can see the diff. Then compile and see if you are able to upload OTA and see the change take effect.
Assuming that works, then flash your code and see if you can OTA that same bin file that just worked. I haven't tested AsyncWebServer in a while, but I don't see any issues noted on my example
