Hi.
ChipWhisperer Lite 2 XMEGA
Working on Part 2, Topic 1, Lab A: Instruction Power Differences (MAIN).
Didn’t get very far.
program_target() doesn’t work.
>>> print(cw.__version__)
>>> print(scope.fw_version)
>>> print(prog)
>>> cw.program_target(scope, prog, "../../../firmware/mcu/simpleserial-base-lab2/simpleserial-base-{}.hex".format(PLATFORM))
>>> #cw.program_target(scope, cw.programmers.SAM4SProgrammer, "~/work/projects/chipwhisperer/firmware/mcu/simpleserial-base-lab2/simpleserial-base-CW308_SAM4S.hex")
5.7.0
{'major': 0, 'minor': 65, 'debug': 0}

Why does find() fail?
