Hello,
Thank you for the timely response.
I realize that this forum post was directed at the CC3220S, while we are targeting a Module version based off the CC3220SF chip. The precise part we are using is CC3220MODSF12MOBR or CC3220MODSF for short.
Our initial tests used the CC3220SF-LAUNCHXL from TI, but now we use our own custom board.
One of the other challenges is the CC3220 part requires extra signalling to program and the firmware baked into the CC3220SF-LAUNCHXL board manages this extra signal. Thus requiring the CC3220SF-LAUNCHXL to program via serial on board or external CC3220 chips. Eventually other programming software will get updated to add this logic but to date that has not happened.
Thanks,
Chris
