Part Number: CC2642R
Hello,
I've been working with the simple_broadcaster example application on custom hardware with some errors during RCOSC calibration.
I have used debugger to trace fault point to function runCalibrateFsm() in the PowerC26X2_calibrateRCOSC.c from the SimpleLink source files
Program gets hung up on this statement, infinite loop waiting for AUX_SYSIF:TDCCLKCTL.ACK to be set.
/* finish wait for AUX_SYSIF:TDCCLKCTL.ACK to be set ... */
while (!(HWREG(AUX_SYSIF_BASE + NONSECURE_OFFSET + AUX_SYSIF_O_TDCCLKCTL) & AUX_SYSIF_TDCCLKCTL_ACK)) {}
I have checked register logs and the required bit (AUX_SYSIF:TDCCLKCTL.REQ) is properly getting set in the previous line.
/* set AUX_SYSIF:TDCCLKCTL.REQ... */ HWREG(AUX_SYSIF_BASE + NONSECURE_OFFSET + AUX_SYSIF_O_TDCCLKCTL) = AUX_SYSIF_TDCCLKCTL_REQ;
I have done the following for debug steps
- Tried on 2 different custom boards
- Tried with / without load capacitors on the 48 MHz oscillator
- Verified application works on LaunchPad
And also read through these application notes to ensure system requirements are met (I do not have a 32-kHz crystal in my custom hardware)
Using 32-kHz Crystal-Less Mode
Running Bluetooth Low Energy on CC2640 Without 32 kHz Crystal
Would it be possible to try to measure the TDC_SRC clock (supposed to be equal to XOSC_HF/2 or 24 MHz) on an output pin?
Or possibly the output of the LF OSC (should measure 32 kHz?)
Any other advice on how to proceed with getting the simple_broadcaster application to run on custom hardware?
Thanks!
