RE: Using customer registers to pass initialization data

Thanks ! I missed that address information in the documentation

Indeed it works with :

$ nrfjprog --eraseall
Erasing user available code and UICR flash areas.
Applying system reset.
$ nrfjprog --memwr 0x10001080 --val 0x195B6635
Parsing parameters.
Writing.
$ nrfjprog --program .my_app_bl_sd_app.hex --verify (without --chiperase, not necessary in this case)
Parsing hex file.
Reading flash area to program to guarantee it is erased.
Checking that the area to write is not protected.
Programming device.
Verifying programming.
Verified OK.
$ nrfjprog --memrd 0x10001080 --n 8
0x10001080: 195B6635 FFFFFFFF |5f[.....|

Perfect !

Hi,

0x80 is a main flash memory. Here's the right way to write UICR:

nrfjprog --memwr 0x10001080 --val 0x195B6635

But --chiperase will clear UICR as well...
