Hi,

    I have met one bug.

when I flash a fw with generic level server , then flash other fw with sensor server ,  the system runs error,  if I use command "nrfjprog --eraseall -f NRF52" to erase first then flash ,the system runs well,   why need to erase first?

error as follow:

Hi,

Are you flashing the firmware using Segger Embedded Studio or nrfjprog?

You need to erase the device first to make space for the new firmware.

Hi,

What command line version are you using?

2)but if I flash a fw with generic level server , then flash fw with generic level server again , in this situation it don't need to erase first , fw will also runs well

Is the firmware unchanged when you do this?
