Hi Gordon,
follow your suggestion, I have changed the csv file from 'stm32f411.csv'(which created by me following the data sheet)to 'stm32f401.csv'(original) in pinutils.scan_pin_file().
the same applied to pinutils.scan_pin_af_file() - from 'stm32f411_af.csv' to 'stm32f401_af.csv'.
and changed the startup file from 'startup_stm32f411xe.o' to 'startup_stm32f40_41xxx.o'
then the build work successfully.
but I'm more confused as I do not understand the root cause.
why the standard startup file(startup_stm32f411xe.o)is not working ?
the pin definitions is slightly different between stm32f401 and stm32f411, why follow strictly with data sheet, without format error, the parser is not working ?
sorry for the curious as I'm keen on understanding the principals & processes how you do it(how to build or port to new device).
thanks for your kindness.
