General • Re: ampy transfers from pico loses bytes

Thanks for your suggestions. I've installed mpremote but now cant get past a Transport.Error.
( I should probably log this on the mpremote forum but it seems you have to write your life history in order to log anything, and I thought someone here might have a quick answer.)


>>To confirm the port number (COM14):
c:\chlorinator_original\LOGS>mpremote connect list

>>Now try and list the contents of the pico flash directory:
c:\chlorinator_original\LOGS>mpremote fs ls

>>ampy seems to have no trouble though:
c:\chlorinator_original\LOGS>ampy -p COM14 ls

c:\chlorinator_original\LOGS>mpremote
Connected to MicroPython at COM14
Use Ctrl-] or Ctrl-x to exit this shell

Any suggestions anyone?
