Bug Description

I'm attempting to program an MSP430F1611 via 'msp430-bsl' and I'm receiving the following error:

$ msp430-bsl --invert-reset --invert-test --swap-reset-test --speed=38400 -r -e -P -p /dev/tty.usbserial-FCV6I5XN null.hex

An error occurred:
'bytearray' object has no attribute 'encode'

Using 'msp430-bsl.py' from the 'historical' branch of mspgcc project works fine:

$ python msp430-bsl.py --swap-reset-test --invert-reset --invert-test --speed=38400 -c /dev/tty.usbserial-FCV6I5XN -r -e -p null.hex

I'm running the latest python-msp430-tools (commit 466), but I saw the same behavior on 444.

Any idea what I'm doing wrong or what could cause that error?

Yes that was a bug introduced by internal changes to use "bytes" instead of strings to be compatible with python 3.x (2to3).

FYI: you get more detailed error messages with the "--debug" switch.

Thanks for the fix! The programming works as expected now:

$ msp430-bsl --swap-reset-test --invert-reset --invert-test --speed=38400 -r -e -p /dev/tty.usbserial-FCV6I5XN blink.hex
Programming: OK
