Hi! Recently I started playing with bluepill and mbed os.
It looks like there are few problems with this.
Problem 1. I found, that when I build with debug and RTOS enabled, compiled binary does not fit into flash. Problem solved by adding extra_scripts = add_nanolib.py to platformio.ini and add_nanolib.py:
Import("env")
env.Append(LINKFLAGS=["--specs=nano.specs"])
Why it’s not default for bluepill? What downside does it have?
Problem 2. I have a problem with unreliable can bus described here:
Any ideas how to diagnose and fix this?
Problem 3. Currently (ststm32 8.0.0) uses mbed 5.15 for bluepill, but there is community effort for mbed os 6.2 here:
What is the proper way of using bluepill with mbed 6.2 and platformio?
