Can I build libmbed.a myself?

[leomonan]

I want to add some debug code inside “class Thread”, but I find this class may be implemented in

ARDUINO_NANO33BLE/libs/libmbed.a
Can I find a way to get the libmbed.a's source code and build it locally?

Hi @leomonan ,
you can just run ./mbed-os-to-arduino -r /path/of/you/mbed-os/local/clone ARDUINO_NANO33BLE:ARDUINO_NANO33BLE from the root of this repository.
The script runs on Linux and probably on macOS (you may need to apply this patch).
I just noticed that the instructions in README are out of date and I'm going to amend them.

Hi @facchinm
Sorry, I tried but got "mbed: command not found" error, I can't find mbed function in this script.
could you please give me some help?

You need to install mbed cli as a prerequisite (https://os.mbed.com/docs/mbed-os/v5.15/tools/manual-installation.html) , I need to amend the documentation to point it out.

Hi @facchinm
I run the below command in /workspace/.platformio/packages/framework-arduino-nrf52-mbedos

./mbed-os-to-arduino ARDUINO_NANO33BLE:ARDUINO_NANO33BLE

and get the error below. Do you know what could be the issue? Thank you in advance.

@trungnq97 this my caused by a compile error(did you modified the source code youself?), you can find the error by run the build command separately:
/home/trung/.platformio/penv/bin/python -u /tmp/mbed-os-program/mbed-os/tools/make.py -t GCC_ARM -m ARDUINO_NANO33BLE --source . --source ./mbed-os/features/unsupported/dsp/ --build ./BUILD/ARDUINO_NANO33BLE/GCC_ARM -v
