Failed to start STP mode!
This is what im getting on my computer(Ubuntu 16.04):
>>> import sqnsupgrade >>> sqnsupgrade.run('/dev/ttyUSB0', 'NB1-40343.dup', 'updater.elf') <<< Welcome to the SQN3330 firmware updater [1.2.0] >>> Failed to start STP mode!
Edit: I'm running this on my computer and I opened as "sudo python3"
Edit 2: I'm trying to do this over UART since i don't have the expansion board aka no sd card.
Edit 3: Tried to do also upload the 'upgdiff_33080-to-40343', same result as I have here.
Uploaded the diff and uploader files to the Gpy with the Pymakr and did the upgrade using the steps of the sd card but changing each path to flash.
@oyarzo-pablo: Try leaving out the first parameter and specify only the *.dup and the *.elf files.
Where are these files located? Are they accessible directly or do they need a path like /sd/updater.elf ?
