compilation error on STM32F411DISCOVERY

Hi Gordon,

I attach a short screen shoot of the diff between two csv files fyi.

without format error, the python script should work properly...

but now just switch to f411.csv file, the compilation is broken: list index out of range

-->

Traceback (most recent call last):
File "scripts/build_pininfo.py", line 50, in

pins = board.get_pins()

File "/Users/dp/Desktop/espmac/scripts/../boa­rds/STM32F411DISCOVERY.py", line 139, in get_pins

pins = pinutils.scan_pin_file([], 'stm32f411.csv', 5, 8, 9)

File "/Users/dp/Desktop/espmac/scripts/pinuti­ls.py", line 197, in scan_pin_file

pin["csv"][head] = pindata[i].strip()

IndexError: list index out of range
