Running the “1-Connecting to Hardware” notebook with an CW Husky, all fine except programming is failing with a timeout when running cw.program_target(scope, cw.programmers.SAM4SProgrammer, "../firmware/mcu/simpleserial-base/simpleserial-base-CWHUSKY.hex")
Running off the latest CW 6.0.0 dev branch on a Linux fresh install of Ubuntu 22. What am I missing here?
Error trace below:

Can you post a picture of your CW313 board so that I can see the jumper settings?
Thanks for the quick reply, here’s the board
Hi,
Can you post the output of print(scope) from just before you run the programming command?
Alex
I’m out of town for the week, will share EOW
print(scope) gives me

I started playing with the labs in sca101 and found by accident that I could run lab 2_1A: I could tun the setup as in compile and upload the firmware and capture a trace. Tryinf to upload a new firmware however results in the same timeout. When I unplug the CW and reset the kernel (sometimes twice) I can get it to work again for once.
Your settings look good, I’m not too sure what’s going on here. Could you try pulling the latest commit and running cw.target_logger.setLevel(cw.logging.DEBUG) before programming?

It doesn’t look like your SAM4S is responding at all. I’ll play around with the bootloader entry code to see if there’s anything unreliable there.
Thanks Alex. Let me know if I can contribute
