cant access flash memory after ota

[p_t]

hi i am using nrf51882 with sdk v 12.2.0. i am trying to use flash memory to store some data for my application. I am accessing flash after initialization.

 When i run code without bootloader then flash read write works fine but when i load bootloader code and load zip by using nrf connect, code runs fine but when it goes into flash write part  code stops (stuck in while loop where it checks NVMC_READY_READY_Busy) in  static void flash_page_erase(uint32_t * p_page).

For read and write , i am using ble_flash_page_write and ble_flash_page_read functions.

Hi,

It's recommended to use the Softdevice flash API if you are going to do flash operations while the Softdevice is enabled. Anyway, could you provide a minimal example so I can reproduce the problem here? It's strange that the NVMC_READY_READY_Busy flag is not being cleared.

Solution is given by Vidar Berg on my other ticket with similar question. Thanks for the solution.
