Description

The boards.txt is missing a "Custom" partition scheme entry for the ESP32S3 Dev Module Octal (WROOM2). This makes it impossible to use a Custom partition scheme for this board type.

Code something like the following should be added to the partition section for this board:
esp32s3-octal.menu.PartitionScheme.custom=Custom
esp32s3-octal.menu.PartitionScheme.custom.build.partitions=
esp32s3-octal.menu.PartitionScheme.custom.upload.maximum_size=33554432

Sketch

Sketch independent

Debug Message

There is no specific error message as such. Any custom partitions.csv files are ignored, and the default partion scheme is used because the custom option cannot be selected.

Other Steps to Reproduce

If the following entry is added to the partition section of boards.txt for the "ESP32S3 Dev Module Octal (WROOM2)" board the issue is solved.
esp32s3-octal.menu.PartitionScheme.custom=Custom
esp32s3-octal.menu.PartitionScheme.custom.build.partitions=
esp32s3-octal.menu.PartitionScheme.custom.upload.maximum_size=33554432

The above fixes the issue, but I would appreciate someone checking the detail and the max_size number.

Note that you can add a boards.local.txt to your esp32 directory with these additional lines.

Hi lbernstone, thanks for the tip. I made a boards.local.txt file with the three lines in it, put it next to the original boards.txt (without my mod), and it compiles fine.

It's a good temporary fix for me until boards.txt is updated.
