Snoopy-HSS: changing partition layout

[schlimmchen]

Moved from announcement (issue 1025):

Snoopy-HSS

It's weird.
When I compile for the S3 size is smaller !?
why is there a 2MB limit when i use the generic_S3 ???

Checking size .pio\build\generic_esp32s3\firmware.elf
Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
RAM: [== ] 24.0% (used 78680 bytes from 327680 bytes)
Flash: [==========] 95.9% (used 1886133 bytes from 1966080 bytes)
Building .pio\build\generic_esp32s3\firmware.bin

In Platform.ini default ENV is still generic_ESP32

Changing partition worked, can also be uploaded Serial via, visual Studio code

Yes, as the S3 is a slightly different processor with a different instruction set, so the code is can be smaller (more efficient instructions, etc.).

I don't know what you mean. The partition table is the same for ESP32-S3 and non-S3.

Only a little under 2MB availabe.
How can i change, that it uses 16MB filesystem when compiling generic_esp32s3

is this part for all boards?
board_build.partitions = partitions_custom_4mb.csv

it's set in platform.ini to 4MB and ESP32 per default...

@Snoopy-HSS Please avoid going off-topic in other issues.

Yes.

You don't. Why do you need that? The new partition layout will use 8MB of flash. It will preserve the littlefs partition (position and size). the app1 partition will go just behind the littlefs partition and will have the same size as app0. You should now be able to edit the partition table CSV yourself.

so, i need to changed platform.ini to board_build.partitions = partitions_custom_16mb.csv ?

Have a look at 2cc0863, which should answer your questions, and go wild 😉 Remember not to slip unintentional changes to platformio.ini in a PR.
