WEB GUI fails to compile for C6+H2 combination (TZ-638)

[orenc75]

Hi,

The thread border router is working great under v5.3 with C6 instead of S3 as the BR and H2 as the RCP. Connection via UART.
However, when I set "Enable the web server in Thread Border Router", the build fails with the following log:

It seems like the defined partitions are too small to accumulate the web server.
Maybe the partition definitions are wrong for C6 as BR? I am using ESP32-C6-WROOM-1 MAN8 and ESP32-H2-MINI1 MBN4.

[orenc75]

ok, I fixed it by setting:
Serial flasher config > Flash size > 8 MB

Also, I changed the partitions.csv to increase the partitions size of ota_0 & ota_1 to be 1664k

I am not sure what the defaults for S3, but maybe you would like to change the default settings for C6?

[chshu]

@orenc75 The current S3 module on Thread BR board is 4M, the default partition table for S3 is the same to C6, but the C6 firmware seems bigger than S3. So please make the change in your own C6 project.

We will probably produce new Thread BR board with 8MB S3 module, we will change the default partition table then.

[orenc75]

Great, thanks for clarifying.
Also, C6 come with both 4M and 8M variants.

Quick question, does it means that the "official" thread border router which come with S3 and 4M does not support web GUI?

[chshu]

The current Thread BR board with 4M S3 could support Web GUI and OTA, but not too much flash space left.

OTA feature could be disabled during development phase, and ota_1 partition is not required, so more space left for ota_0.

[orenc75]

OK, thanks for your answer. I am closing the issue.
