nrfjprog --memwr 0x10001080 --val 0x01010101 shouldn't fail second time

[dgerman]

nrfjprog checks the target for 0xFFFFFF before attempting to write.

It should be successful not only if attempt to write the same value as is already present but also

if the value to be written is only  writing 0s where there are existing 1s.

For example  0x10001080  contains FFFFFF00 writing 00FFFF00 should succede 

Tank you.

Violating nWrite won't get you an invalid value immidiately. You would get a weak cell that could change its value inside the (otherwise guaranteed) time period in the PS.

You don't want your flash data changing in, for example, one or two years instead of 20.

Has there been any change in ideas on nrfjprog's requirement that destination must be FFFFFFFF ?
