Description

Inconsistent naming convention for 32MB partitions breaks Arduino IDE's Language Server.
I'm taking a swag at this based on the output from the Language Server logs:

cmd /c if not exist "C:\\Users\\TerryPhillips\\AppData\\Local\\Temp\\arduino-language-server668929682\\build\\partitions.csv" COPY "C:\\Users\\TerryPhillips\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\3.1.0-RC1\\tools\\partitions\\app5M_fat24M_32MB.csv" "C:\\Users\\TerryPhillips\\AppData\\Local\\Temp\\arduino-language-server668929682\\build\\partitions.csv"
The system cannot find the file specified.

In the boards.txt config, the partition entries are as such:

esp32s3-octal.menu.PartitionScheme.app5M_fat24M_32MB=32M Flash (4.8MB APP/22MB FATFS)
esp32s3-octal.menu.PartitionScheme.app5M_fat24M_32MB.build.partitions=large_fat_32MB
esp32s3-octal.menu.PartitionScheme.app5M_fat24M_32MB.upload.maximum_size=4718592
esp32s3-octal.menu.PartitionScheme.app5M_little24M_32MB=32M Flash (4.8MB APP/22MB LittleFS)
esp32s3-octal.menu.PartitionScheme.app5M_little24M_32MB.build.partitions=large_littlefs_32MB
esp32s3-octal.menu.PartitionScheme.app5M_little24M_32MB.upload.maximum_size=4718592

But under the FlashSize option, it is as:

esp32s3-octal.menu.FlashSize.32M.build.flash_size=32MB
esp32s3-octal.menu.FlashSize.32M.build.partitions=app5M_fat24M_32MB

Debug Message

Arduino IDE Language Server log:

cmd /c if not exist "C:\\Users\\TerryPhillips\\AppData\\Local\\Temp\\arduino-language-server668929682\\build\\partitions.csv" COPY "C:\\Users\\TerryPhillips\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\3.1.0-RC1\\tools\\partitions\\app5M_fat24M_32MB.csv" "C:\\Users\\TerryPhillips\\AppData\\Local\\Temp\\arduino-language-server668929682\\build\\partitions.csv"
The system cannot find the file specified.

Other Steps to Reproduce

Choose a different memory size, the Language Server will function as expected.
Modify the following and the Language Server will function as expected.
esp32s3-octal.menu.FlashSize.32M.build.partitions=large_fat_32MB
Or create a copy large_fat_32MB.csv as app5M_fat24M_32MB.csv and the Language Server will function as expected...

Hi @microfoundry, I was testing with both Arduino IDEs and with Arduino-cli commands to set the FlashSize in FQBN, but the partition used was always the default, so the one undertake FlashSize menu was not overwriting it, and also there is no overwrite for upload.maximum_size. I have opened a PR that removes all the partition overwrites from the FlashSize menu.
