Hello,
I've created a custom board with CC2652R1F, see the picture below.
I'm using the DCDC/GLDO output to provide the VDDR power.
When I set the 'Enable DCDC' flag in the syscfg, the controller is unreachable after initialization of the startup functions provided by TI.
With the debugger I found out everything goes fine until the next function:
ResetISR -> SetupTrimDevice -> TrimAfterColdResetWakeupFromShutDown -> SetupAfterColdResetWakeupFromShutDownCfg1
Inside the last function the AON_SYSCTL:PWRCTL.DCDC_EN and AON_SYSCTL:PWRCTL.DCDC_ACTIVE will be set based on the 'Enable DCDC' flag in the syscfg.
The DCDC_EN bit is successfully set.
When the DCDC_ACTIVE bit is set, the debugger will lose the connection and I can't figuring out what is happing next.
Questions:
1. Based on the hardware of my custom board, it is possible to use the DCDC instead of the GLDO. Correct?
2. Is the controller going into Standby mode and this is why I am losing the connection after setting the DCDC_ACTIVE bit?
If so, is the DCDC not possible in Active or Idle mode?
Looking forward to some reactions.
Kind regards
