Could I write or update flash without softdevice ?

Hi, Could I write or update flash without softdevice ? Due to I must update softdevice on our product, but it doesn't have any JTAG Interface, so, I want to use our application to reprogram softdevice by UART interface.

Hi,

Yes, you can write the flash without the soft device. You should look at the flash write example project provided by the SDK. It shows how to erase and write the flash using the NRF_NVMC directly rather than using the soft device API.
