Pynrfjprog error

[AntoineB]

Hi,

I develop a python software that flash 2 nRF chip (nRF52840 & nRF9160) with pynrfjprog (version 10.15.2). All the dll are wrapped into the generated exe and the jlink_arm_nrf_worker.exe is also wrap.

This software can run without issues on my laptop but when I try tu run it on another computer (that had VC redist 2015 x64), it's no longer possible to erase/flash the nRF chip

The both errors bellow are raised on two different computer :

-102 JLink arm dll error.

or

-151 nrfjprog sub dll could not be opened.

What can be the cause of this errors and is that possible to fix them ?

Best regards,

Antoine

Hi,

From the pynrfjprog Dependecies list:

• J-Link Software and Documentation Pack will install the JLink libraries pynrfjprog depends on in the correct installation directory.

Have you installed this on the secondary computer that you are testing with?

Best regards,
Jørgen

Hi,

This package was already installed but even after re-install it, there is the same problem : error -102 Jlink arm dll error.

(But I have this error on the 2 computer after re-install the package so it improve a little)

Best regards,

Do you mean that the error was fixed on one computer by re-installing J-Link?

Or do you no longer see the "-151 nrfjprog sub dll could not be opened." error?

Can you check if you see the same issue with latest version of pynrfjprog (v10.16.0)?

Hi,

I mean that the -151 is not raise anymore.

But the error was finally an HW mistake on my side, sorry to have create this ticket whithout double check this part.

No more error with pynrfjprog after setup everything correctly.

Best regards,
