External memory EE instead of FF

[Hubersch]

Hello everyone,

My empte memory is displayed as EE instead of FF after i cleared the memory.

I use commandpromt to check memory:

nrfjprog --qspicustominit --memrd 0x120ff000 --w 16 --n 0x100

Does anyone know what goes wrong?

Hi, 

How do you clear the memory?

Are you able to see FF with the command  nrfjprog --eraseall ?
