flash space not enough for esp32c3 #14

Closed dennis4lora closed 4 months ago

When building for esp32c3 using PlatformIO, it failed with below error:

...
Linking .pio/build/esp32c3/firmware.elf
Retrieving maximum program size .pio/build/esp32c3/firmware.elf
Checking size .pio/build/esp32c3/firmware.elf
Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
Error: The program size (1050666 bytes) is greater than maximum allowed (1048576 bytes)
*** [checkprogsize] Explicit exit, status 1

Flash: [==========]  100.2% (used 1050666 bytes from 1048576 bytes)

So it's time to take some actions to optimize the flash usage now...

Interesting, it fits for me:

No, you were right. Fix in #15 .
