CC3220SF-LAUNCHXL: Device is unable to boot up when Power on Reset is performed during factory reset

Tool/software:

Hi team,

I am trying to perform factory reset operation on my device using host driven sl_FsCtl() API. During the factory reset operation it is observed that it takes around some 40secs to complete the factory reset and return the status by NWP. Unexpectedly, POR has be performed while the device perform factory reset operation. When POR is performed, the device doesn't seem to boot up at all and was in indefinite hang state as we don't have a watchdog implemented. Please suggest a way to make the device boot up even when POR is performed during factory reset.

Thanks,

Thanks Rogelio for the information. After glancing through the guide provided and I came to know that I have connected the SOP1 jumper (as it is not recommended), which was causing the issue. When I removed it, device seems booting up properly even when POR is performed.

I have one more query related to factory restore. When I flash my device, I have set the Country code as US and during the application I was changing the country code to another. But when the factory restore operation is performed on the device, I notice that the country code reverts to US. Is there any way to retain the country code when factory restore is performed?
