it's been a very long time since any of us have worked with the cortex. can you post the output of pros lsusb

[mattfbacon]

If if I had any choice I wouldn't be using Cortex. Anyway...

[mattfbacon]

Also thanks for the quick response.

[mattfbacon]

Any insight here? I'd love to use PROS if I can.

[nathan-moore]

I'd love to use PROS if I can.

Can other programs upload to your cortex? What version of the cli are you running on? 3.3.2 seems to be the kernel version.

[mattfbacon]

I'm able to download via RobotMesh Studio (which is what we're currently using). Interestingly, downloads over the USB A-to-A directly connected to the cortex do work with RMS, despite the fact that A-to-A download is broken and/or not implemented in PROS on Linux.

I was also not able to download with PROS on Windows. Can't remember the exact error ATM though.

[mattfbacon]

What version of the cli are you running on? 3.3.2 seems to be the kernel version.

3.2.2 for the CLI. How would I check the kernel version?

[nathan-moore]

The kernel version shouldn't matter. Do you mind giving an earlier release a try? https://github.com/purduesigbots/pros-cli/releases/tag/3.1.0

[mattfbacon]

Will do next time I get a chance.

[mattfbacon]

Now I get the error: "Device never ACK'd to 49".

[mattfbacon]

Can you give me the specific command I should run? I might be downloading it incorrectly.
