Today while cleaning I found an old stm32 board carrying an STM32F030F4P6.
Turns out that PlatformIO supports it so just for fun I tried to blink some lights.
I couldn’t find my stlink at home but openocd can use a buspirate as a programmer.
It took a while to upload but after that I was able to launch gdb.
And the light was dead.
Strangely enough poking at the memory showed that the code indeed was there. After a long pause to think I noticed that the boot 0 jumper was misplaced.
The lights flashed and there was much rejoicing.
