|
|
|
|
|
|
|
|
# Instructions:
|
|
|
|
|
# - connect to a Panda
|
|
|
|
|
# - run selfdrive/boardd/boardd
|
|
|
|
|
# - launching this script
|
|
|
|
|
# - turn on the car in STOCK MODE (set giraffe switches properly).
|
|
|
|
|
# Note: it's very important that the car is in stock mode, in order to collect a complete fingerprint
|
|
|

|
# until all messages are received at least once
