I'm using arduino-cli to program an ESP32-S2. If I compile my sketch using the default partition scheme

> arduino-cli compile -b esp32:esp32:esp32s2 sketch

a lot of space is allocated for SPIFFS and OTA, which I don't use.

Sketch uses 646558 bytes (49%) of program storage space. Maximum is 1310720 bytes.
Global variables use 39540 bytes (12%) of dynamic memory, leaving 288140 bytes for local variables. Maximum is 327680 bytes.

Thus. I'd like to use the huge_app scheme, as defined in the boards.txt:

esp32s2.menu.PartitionScheme.huge_app=Huge APP (3MB No OTA/1MB SPIFFS)
esp32s2.menu.PartitionScheme.huge_app.build.partitions=huge_app
esp32s2.menu.PartitionScheme.huge_app.upload.maximum_size=3145728

However, selecting it doesn't have any effect:

> arduino-cli compile -b esp32:esp32:esp32s2 sketch --build-property build.partitions=huge_app
Sketch uses 646558 bytes (49%) of program storage space. Maximum is 1310720 bytes.
Global variables use 39540 bytes (12%) of dynamic memory, leaving 288140 bytes for local variables. Maximum is 327680 bytes.

Is my command line incorrect? Why is arduino-cli not using the specified partition scheme?

  • according to platform.txt it is build.custom_partitions the value is the selected partitioning from boards.txt

  • Thanks for your suggestion, I've checked platform.txt and found custom_partitions as well. Unfortunately, it didn't help: arduino-cli compile sketch --build-property build.custom_partitions=huge_app results in Sketch uses 646558 bytes (49%) of program storage space. Maximum is 1310720 bytes.

  • Are you uploading the bin file by arduino-cli? Commented Jul 25, 2023 at 23:06

So, it turns out I have to add another build property:

> arduino-cli compile --build-property build.partitions=huge_app --build-property upload.maximum_size=3145728 sketch

where the upload.maximum.size is from the boards.txt file. Indeed, a maze of twisty little files, all alike.
