Dear all,

I wanted to automate programming of my microcontroller nRF52832 with j-link BASE Compact using Command Line Interface (JLink.exe), calling the script from LabVIEW. I have to automate some operations, currently done with nRFgo Studio:
- selection of "nRF5x Programming"
- selection of a file to program in region "Program SoftDevice", click on "Program" then "Verify"
- selection of a file to program in region "Program Application", click on "Program" then "Verify"

First, I'm testing the commands from Command Prompt And I've some difficulties... This is what I've done (in Bold, commands I've typed):

O.K.?

When loading, a windows appears with a pogression bar.
- how to send the command "Verify"?
- how to make the difference under flashing Program SoftDevice and Program Application? I'm not sure, but maybe the second load crushes the first one...

Finally, I've tried to create a file "script.jlink" with those commands:
erase
loadfile C:\AppSBZ\Sources\SoftDevice_s132.hex
loadfile C:\AppSBZ\Sources\nrf52832_02122019.hex
r

I wanted to call it like this:
"C:\Program Files (x86)\SEGGER\JLink\JLink.exe" -Device NRF52832_XXAA -if SWD -speed 4000 -CommanderScript C:\AppSBZ\Sources\script.jlink


But I definitively doesn't work, I don't understand why...
I work with a Windows 10 Enterprise Computer (version 1903), a programmer j-link BASE Compact (Version 10.10, Date 19-44, Part 8.19.00, S/N: 820102851), SEGGER J-Link Commander V6.62d, Firmware J-Link V10 and nRFgo Studio 1.21.2.10

Is it possible to help me to find a way to solve my problems? Thank you per advance!

Regards,

Francis Millerot

Hi Fabian,

Thank you for your response. I've tried again, and now it's running...
I think it was because I still was inside JLINK.exe when I've tried to call my command line.
Sorry for the disturbance, all is in order.

Regards,
