[nRFgo] How & when to verify the hex file?

[Chester]

Hi,

I'm using v1.21 nRFgo. As programming 51series ,

(1)I want to know if the program check the hex file before the log dialog shows "programmed successful"?

(2)And what kind of method nRFgo apply to check the Integrity of flashing?

(3)I've already checked some discussion on forum, it seems that there no built-in register/function provide user to check firmware intergity when as readback protection. Is that right?

1.nRFGo Studio is just a GUI on top of the commandline tool nRFjprog, which has a verify option

nrfjprog --program <name-of-hex-file>.hex --verify

which is used when you press program in nRFGO Studio

2.With the verify option set, nrfjprog will flash the hex file to your device, then read-back the same flash area and compare it with the original hex-file.

3.No, with read-back protection enabled it is no longer possible to read-back the firmware and verify that it has been flashed correctly.
