Hello, please try to downgrade your Python version as Øyvind suggested. I'm hoping this will fix the issue you're seeing with pynrfjprog.

Hello, no it is not possible to update the PC to Windows 10.

Thank you for the support

Hello,

It sounds like the issue may likely be related to the Windows version. Any chance you can upgrade to Windows 10 on this particular PC? We are no longer testing our releases against Windows 7 as Microsoft stopped supporting it last year (link). I also think it would be better to get the Python script working to allow for automation of the programming process. Øyvind will follow up on that.

Hello,

I tryed and disconnect some of the serial ports of out test system, but the Segger-ARM-Flasher will not displayed in the device list.

I also connect the same Segger-ARM-Flasher to the PC (without USB-HUB) and it will not displayed.

The only difference between the 2 PCs are that at the test system PC Windows7 32 bit ist installed. (device not displayed)

At the developement PC Windows10 64 bit is installed (device displayed and can selected)

Hello.

Yes ist only 2 serial ports on the PC i can see the Segger-ARM-Flasher in the device list.

If 6 serial ports on the PC i can not see the Segger-ARM-Flasher in the device list.

J-Link = 6.88a

Does the programmer show in nRF connect if you only connect one Segger-ARM-Flasher?

And just to confirm, do you see the Segger-ARM-Flasher programmer listed in the device menu in the nRF connect programmer app on this PC?

The developer also asked if you could check if both PCs are running the same version of J-link.

Yes the are connected via USB HUB and the programming of the SLW-FW via JFlash works by selcting programmer via serial number.

I dont try to program the application FW via nrfprog. We use JFlash from Segger.

Hello,

Thanks for the clarification. I didn't know that the J-Flash could work, we only state J-link support in the documentation.

[quote user="christian.bruckner"]Only at this production system when 6 serial ports avaiable and 2 Segger-ARM-Flasher exist only 5 devices displayed at the selection menu.[/quote]

Does it work when you have fewer programmers connected? Also, are they connected via a USB Hub?

[quote user="christian.bruckner"]nrfprog command line [/quote]

nrfjprog does not suppor modem updates. But does it work reliably when you program the application FW?

Do you always get this error? Can you post a screenshot of the error here?

Hello, it is working with the Segger ARM-Flasher.

At a other System (PC) when only 2 serial ports avaiable the Sergger-ARM-Flasher will be displayed with his serial number. Also the "Modem update" function with the Segger-ARM-Flasher works at this System(PC).

Only at this production system when 6 serial ports avaiable and 2 Segger-ARM-Flasher exist only 5 devices displayed at the selection menu.

Also the programming of the nRF9160 SLM FW can do with the Segger-ARM-Flasher and JFlash-Program.

This is a fall back solutopn (manual programming) because i tryed many other solutions for production programming but nothing works.

nrfprog command line -> Not works with the "modem update" instructions (https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnan_041%2FAPP%2Fnan_production_programming%2Fintro.html)

nrfprog.dll not works because there are need of a DLL-Wrapper with callback functions

pynrfprog (with Python) not works -> Get a DLL-Error message and it stops (https://devzone.nordicsemi.com/f/nordic-q-a/53208/updating-nrf9160-modem-firmware-through-the-command-line)

So we have no more idea at our compony how do a good and stabil "modem update" for production.

Hi,

The programmer app requires a J-link debugger, so I'm afraid it will not work with yourJ-Flash programmers. But is there a particular reason you want to use this app in production? Segger should have programs that are more suitable for this purpose.

Best regards,
