SD Card write error: OSError: [Errno 5] EIO
I am getting this error when I am trying to log exception on my SD card.
This is my code:
sd = SD() os.mount(sd,'/sd')
try: with open('/sd/debug.log', 'a') as f: f.write('starting loop') f.close() mainloop() except Exception as e: with open('/sd/error.log', 'w') as errorFile: errorFile.write('test') errorFile.close() sys.print_exception(e) machine.reset()
My SD Card is a 32GB Fat32 formatted card, and I can successfully read the debug.log file on my mac.
I don't understand why the second write in the error.log failed ... any help would be appreciated ...
@robert-hh In my main loop, I have simulated an Exception with
But it's working when I am writing to /flash/error.log, thanks for the tip. I just want to let my lopy running for a week and wanted some feedback if an exception have occured.
@geda For trial, I replaced the mainloop() by a 1/0 statement, just to cause an exception,, and all worked a expected. So maybe the error which happens in your test case has an impact on SD card I/O. What happens if you try writing to /flash/error.log instead?
