Other Parts Discussed in Thread: UNIFLASH, CC3200, , CC3100
Hi there,
I've only seen this issue on E2E a couple times, with no actual resolution.
In attempting to connect to the CC3200 using UniFlash (3.4.1), I am getting the following:
[17:25:14] Begin ServicePackProgramming operation.
[17:25:15] INFO: > Executing Operation: Connect
[17:25:15] FATAL: --- Can't connect to device !! ---

I've tried resetting the launchpad, with and without SOP2 Jumper, with and without J8-J11.
I have successfully connected to the device on MacOS in the past as well, but the failed ACK is occurring there now too as the CCS debugger is no longer connecting. I've also tried using cc3200tool but ACK failed there too.
Can anyone describe what's happening? I suspect something is wrong with the FTDI device on the Launchpad, but can't find enough information in the documentation to figure it out.
Thank you!
