I have a ESP32-C3-MINI-1U, and I’m trying to build a sample for this board it’s on. The build fails right at the end because of the flash used:
Checking size .pio\build\ESP32-2424S012\firmware.elf
Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
RAM: [=====Error: The program size (2866476 bytes) is greater than maximum allowed (1310720 bytes)
===*** [checkprogsize] Explicit exit, status 1
] 80.3% (used 263212 bytes from 327680 bytes)
Flash: [==========] 218.7% (used 2866476 bytes from 1310720 bytes)
This processor should have 4MB flash, so this size should be totally fine.
The board JSON (custom) is as follows:

I can’t figure out where I’m going wrong to enable the use of 4MB flash, or I’m really misunderstanding something.
Doesn’t seem relevant, but here is my platformio.ini:
[env:ESP32-2424S012]
platform = espressif32
board = ESP32-2424S012
framework = arduino
build_flags = -D LV_CONF_PATH=my_lv_conf.h -I lib
