tmedicci opened a new pull request, #3542:
URL: https://github.com/apache/nuttx-apps/pull/3542
## Summary
Reduce general firmware size by optimizing Python-related sources.
## Impact
Impact on user: Yes. Enable reducing firmware size when
`CONFIG_INTERPRETERS_CPYTHON` is enabled.
Impact on build: Yes. Reduce firmware size by ~6% (tested on ESP32-P4)
Impact on hardware: No.
Impact on documentation: No.
Impact on security: No.
Impact on compatibility: No.
## Testing
Build `esp32p4-function-ev-board:python` defconfig before and after applying
this patch.
### Building
```
make -j distclean && ./tools/configure.sh -S
esp32p4-function-ev-board:python && make -s -j$(nproc)
```
### Running
After flashing the device, just run `python` on NSH to ensure that it's
being properly initialized.
### Results
