nRF_SoftReset issue query!!

[Urvisha Andani]

Hello,

I am using nRF52832 EVM board with SDK 15.3.0 in SEGGER studio IDE, win 10.

When I am implementing sd_nvic_SystemReset(); in my code, that time i am not able to write data  in flash.

Before writing data device is getting reset. So data is not getting store in flash

Solution done by me:

1. I have tried with delay after writing data to flash, then reset the device, still facing same issue.

2. Another solution,I have created a timer of 5 sec and after writing data in flash Timer is getting started and after 5 sec device is getting reset. In this scenario it is working fine.

Any solution/ suggestion why it is behaving in this manner?

Regards,

Urvisha

HI,

Writing to flash is asynchronous.

When using the SoftDevice API, you will get a SoC event from the SoftDevice when the flash operation is complete or has failed, i.e. NRF_EVT_FLASH_OPERATION_SUCCESS or NRF_EVT_FLASH_OPERATION_ERROR.

When using SDK libraries, there are other events that signals that a flash operation has succeeded or failed, depending on the flash library used.

In any case you should wait for the appropriate flash operation event before resetting the device.
