Program page success but nothing programmed

[Pra_Engr]

In the nRF52832 (Laird BL652 module) I have programmed.

MBR + SoftDevice from 0x0000 0000
Application from 0x0002 6000 ~ 0x0005 927C

Now trying to program additional application hex.

nrfjprog.exe -v
nrfjprog version: 8.5.0
JLinkARM.dll version: 6.44h

nrfjprog.exe -f NRF52 --erasepage 0x00065000

Using nRF Go Studio 1.21.2,
....hex programmed successfully.
Verification failed.

And there is nothing in the page 0x00065000.

I don't see anything wrong here.
Do you?

Please let me know the solution.

Hi,

nRFGo studio is deprecated and replaced by the Programmer app in nRF connect for Desktop. This may explain the verification error. Please try the following to see if you get the same result:

1. nrfjprog --program file_1.hex --verify --sectorerase

2. nrfjprog --memrd 0x65000 --n 0x1000

Thanks for your reply

I tried the following

C:\>

File layout is recognized properly with the address as expected

And it does not overlap with other regions

If I do  Erase & Write , it will erase whole chip.

Write option is disabled !

Thanks for confirming. The page appears to be erased which is strange. Is it possible that your app may be erasing this page at runtime? I.e., do you get the same result if you only program this hex file?

nrfjprog --program file_1.hex --chiperase

[Pra_Engr]

Sorry. My other parts of the app don't erase this section !

Yes,  with chiperase option, it erased the whole flash, and successfully written only this application hex

Now,

I did 

nrfjprog --program file_1.hex --chiperase

and then did add hex file to this existing app

And then Erase & Write , writes only the applications part (without file_1.hex)+SoftDevice + ..

Though file_1.hex is displayed in the File Memory Layout , it is not programmed ?
