CC2744R7-Q1: Hitting Exception_handlerSpin

Other Parts Discussed in Thread: SYSCONFIG

Hi Forum,

I am working with the CC2744R7 target. After changing the target device in SysConfig, I flashed the basic_ble example. I also tried flashing the HSM image before programming the application binary.

While debugging, I observed that the application enters Exception_handlerSpin() after the following call sequence:

vTaskStartScheduler() → vStartFirstTask() → xPortStartScheduler() → vTaskStartScheduler() → Exception_handlerSpin()

I have reproduced the same behavior with both SDK versions 9.20.00.81 and 9.14.02.16.

It appears that all BLE example projects in these SDK versions exhibit the same issue when built for the CC2744R7 target.

Could you please let me know if any additional configuration or initialization is required for the CC2744R7, or if there are any known limitations with the current SDK support for this device?

Regards,
Vaibhav

Hello Vaibhav,

Yes, we are aware of this issue and have a fix. In Sysconfg, please navigate to the NVS Region section of the settings and change the region from 0xE5000 to 0xB5000. I was able to reproduce the issue on my end, and this fix resolved the issue successfully so please test on my end and let me know. Thanks.
