BUG: Sketch compiled under Platform is MORE BIGGER than expected

gpezzella · January 13, 2023, 7:18pm

Hi
this is under arduino 1.8.19:
Flash: 11622 byte (37%) Max 30720 byte.
RAM: 1777 byte (86%) Free 271 byte

This under PlatformIO
RAM: [====Error: The program size (39434 bytes) is greater than maximum allowed (30720 bytes)
====*** [checkprogsize] Explicit exit, status 1
= ] 87.4% (used 1789 bytes from 2048 bytes)
Flash: [==========] 128.4% (used 39434 bytes from 30720 bytes)

[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino

How it is possible???

We can only start exploring that when we know the full code, the exact Arduino IDE configuration (tools menu), the exact Arduino IDE core version and all libraries with their exact used version.

Hi
here a link for download project:

The same code with same library under arduino ide 1.8.19 compile well

Please reply me soon

With the PlatformIO project you upload and building it I get

Which are the exact number of used bytes in RAM and Flash like you have in the Arduino IDE

Did you remove the .pio folder and press build again to get a clean rebuild?

Hi just done but don’t work…

Why build in debug mode? Turning off optimizations will lead to a much bigger code size. Are you building using the “Start Debugging” button using the regular Build project task? Do you have any build_type = debug statement in the platformio.ini (docs)?
