how to modify partition table?

[bsdinis1]

your build script works perfectly fine, I am able to flash it to my generic ESP32-S3 R8N16 with the devkit-c1-8m.conf configuration, but when I attempt to modify the partition table it gets overwritten by your script, and after multiple attempts I've given up.

and now I am trying to follow this guide but when I try to flash the xipImage I get the following error Exception: Input file size exceeds partition size, even without modifying the partition table.

ESP32DE's guide is a little confusing so I noted down the exact steps in a text file so that it's easier to follow, I was hoping someone could spot what have I done wrong or what have I missed that's preventing me from flashing the xipImage while the rest of the files flashed without any errors.

from ESP32DE's guide I replaced xtensa-2023.02-fdpic with xtensa-2024.08-fdpic, could this be the cause of my issue? it is very painful to test this as the whole build process takes about 2 or 3 hours due to very slow download speeds from GitHub.

any help is greatly appreciated

when I attempt to modify the partition table it gets overwritten by your script

The script doesn't change the partition table, but it changes the IDF configuration, here: https://github.com/jcmvbkbc/esp32-linux-build/blob/master/rebuild-esp32s3-linux-wifi.sh#L122
If the IDF configuration is modified you can copy it back, or save it under a new name and use that name in the build scripts configuration.

and now I am trying to follow this guide

These scripts are meant to be the guide, you could follow them and they are known to produce a working result.
