6 years ago A quick update, I noticed that the firmware. files were tiny compared to the firmware. files generated by the other builds.
Recompiling with the V=1 option revealed that the linker isn't finding the "_start" symbol, so the optimizer is probably optimizing out all of the code:

Hello,
First, thank you for compiling this package!
I found a minor bug in your build instructions, and the MicroPython build system is a bit too involved for me to quickly fix.
I have to run "make BOARD=BLACK_F407VE" twice to complete the build successfully. For some reason the HAL drivers are not built during the first pass.
Here is the relevant stack trace:
