RTOS/CC2652R: SysCtrlSystemReset not booting up sometimes

Could you please elaborate? When do you use SysCtrlSystemReset  and how do you know that the board didn't boot? Do you see a pattern when the board boots and when it does not boot? 

Any feedback? 

Hi, 

We use this after OAD , to reboot the system and in between in case needed to reboot our application. We did not see any UART logs coming up or anything on the LCD display after reboot sometimes. 

Thanks,

Anu 

Hi Anu,

See post below, if this issue is relate to Halt In Boot. If so the SysCtrlSystemReset() should work properly if there is no JTAG connection and your powered externally.

In addition, was it any difference in the test setup when SysCtrlSystemReset() managed to reset the system and when it didn't? 

No, There is no difference in setup in both cases. 

Hi TER,

I checked the link  . But our board is externally powered by a battery not connected to debugger . Still we get the issue sometimes . We need a hard reset after this to get the board boot . 

Please let us know if any idea why it is not booted sometimes even not on debugging.

Hi,

Does the same happen if you use HAL_SYSTEM_RESET()?

Hi,

I just confirmed SysCtrlSystemReset() works using Simple Peripheral for CC2652RB Launchpad. I just call SysCtrlSystemReset() at SimplePeripheral_performPeriodicTask().

After finishing OAD, there should be code line to reset the device. Why do you need to call system reset again?
