nrf5340 programming of network core flash

[kpreiss]

Hi,

Is it possible to program the FLASH memory on the network core from the application core WITHOUT having to run a bootloader on the network core?

Best,

Kurt

Hi Kurt,

We have a similar case here that you can have a look : https://devzone.nordicsemi.com/f/nordic-q-a/76734/flash-write-issues-with-nrfx-on-nrf5340

From my understanding it should be possible, as long as the SPU is not configured so that the netcore is secured.

The post you linked to pertains to an application running on the network core writing to the application core flash memory.  We would like to have an application running on the app core write to the network core FLASH memory.

Hi Kurt, 
Have you tried to test. I don't think there is a difference.
