flash_page_erase fail on s110

[max]

Hi

I using nRF51822 ble_app_uart project with softdevice 7.0.

I need to manage my internal flash memory map so i cannot use pstorage libarytest main.txt.

So i try to use flash_page_erase(addr) and received hardfault error

What hardfault error do you get?

If you have enabled the softdevice you should use the wrapper functions for accessing the flash.

As Asbjørn stated above, from my experiments I have made with this I can confirm that the issue is that you don't use softdevice functions. Softdevice takes care of numerous interfaces including Flash. You will have to use sd_flash_page_erase. The complete list of all dependencies and where the access to peripheals is restricted and where not is available in softdevice datasheet.
