Hey Jerry,

Please see the following thread: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/827042?CCS-CC1312R-About-enabling-CC1190-by-define-CONFIG-RANGE-EXT-MODE

Unfortunately the files have been removed from the project and is not configurable via SysConfig. I would recommend importing the files from the CC1310 version and verify that the pins mapped are the ones in your configuration. The pin initialization code is in board_palna.c.

Normally the challenge in supporting Skyworks PA the control logic is different. So mapping the LNA_EN and PA_EN from the RFC is not enough.

Ref RC1882HPCF and RC1892HPCF from Radiocrafts that uses CC1312+ SAW + PA. www.radiocrafts.com

Solution is to map PA_EN out to GPIO to control PA/ /not LNA) signal on extern PA and then use global RFC interrupt to turn on PA chip (wake up from sleep)

whenever the RF core is turned on/off.
