CC3220SF-LAUNCHXL: Uniflash unable to connect to off-Launchpad cc3220sf

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH, CC3220SF

I am trying to use uniflash(version 4.2)  to program a CC3220SF that is not on a Launchpad. I am aware of the auto reset issue, and I am trying to connect through the xds110 on the Launchpad to the other cc3220sf via UART. I have been unable to connect so far. I am using the rst,rx,tx, and gnd pins on the Launchpad to connect to the other cc3220sf. Jumper is present on SOP2. Uniflash gives the timeout reading data error when trying to connect. I have triple checked connections, so I must be overlooking something here. Any advice is appreciated.

  • Hi John,

    Have you already reviewed the CC3220 Production Line document? Specifically Section 5.4 "UART Hardware Connection Usgin the CC3220 LaunchPad"

    The launchpad pins being used should be the following I believe:

    Make sure you're choosing CC3220SF using serial UART connection within Uniflash initially:

    Hope this helps,
