nrf5340 debugging restart is too slow

[vinodsdw]

I was using earlier IAR and embedded segger IDE for previous nrf52 versions.

Recently Nordic moved to VS code and things are not smooth as earlier.

When I click debug, it loads the firmware to the nrf5340.

While debugging , if I want to restart the code from beginning, it loads the entire firmware again by erasing the chip.

This is really annoying and I am not sure why it is loading again by taking several seconds ?

Is there any workaround for solving this, coz it really affects the debugging time.

With older version of nRF52 and also with nRF51, they did not have the extra layer of security in the APPROTECT to shield the chip from unwanted debug access. nRF53 does not allow erase and writing to protected flash pages unless a recover is performed. This is the change in the hardware behavior and not just in the IDE.
