How to implement Lock entire chip from readback during mass production programming

[helen]

Hi

           1、The customer wants to set read protection during batch programming，Customers use offline programming during mass production；

           2、In addition to using nRFgo Studio to implement lock entire chip from readback, are there any other ways to implement lock entire chip from readback?

Hi,

I would recommend using nrfjprog for batch programming.

E.g.

/* Erase chip followed by programming of the FW image */

nrfjprog --program <fw image>.hex --chiperase

/* Enable readback protection */

nrfjprog --rbp all

Best regards,
