Why the nRFgo Studio failed to program HEX file while the "Lock entire chip from readback" has been checked?

[stephen]

Hi all,

I programed hex file (blinky example) to nRF51DK via nRFgo Studio, and the board could work fine (keep blinky). However, the nRF51DK will work FAIL (LEDs are not blinky) while the "Lock entire chip from readback" has been checked even though the nRFgo shows "programmed successfully".
Why?
And, is there another way to successfully set "lock entire chip from readback" ?

chip: nRF51422 QFACA10 (0x0086)
nRFgo version: 1.21.2.10
OS: win10 64bit
example: blinky (w/o softdevice)

Have a look at this thread devzone.nordicsemi.com/.../

I think you will need to use the nrfjprog program in the command line tools to reprogram the board after this is set. You will need the --recover option. I'm not sure if nrfgo studio will do this.

--recover option works. Thank you!
