VSCode Actions Flash on OSX missing JLinkARM.dll

[Laur1n M.]

ERROR: JLinkARM DLL load failed. Try again. If it keeps failing, please
ERROR: reinstall latest JLinkARM from Segger webpage.

I tried downloading three different versions of the Segger JLink Package for an m1 Mac. (https://www.segger.com/downloads/jlink/?step=1&file=JLink_510d)

I tried 7.66a and currently have 7.66b installed. And also some 5.xx version. But all of them are missing this file. 

When using Run - Start Debugging in VSCode it all seems to work fine but the "Flash" Action just doesn't work. 

Happened with nRF Connect SDK 1.9.1 and 2.0.0.

This would not be an issue but currently I try to run BLE audio examples on a nRF5340 but there seems to be an issue where it hangs in the

hci_core.c:3681    err = bt_dev.drv->open();

to which this thread says (https://devzone.nordicsemi.com/f/nordic-q-a/73237/nrf5340-debugging-using-segger-embedded-studio-for-bluetooth-related-apis) that one must make sure that the network core gets flashed. But I don't see an option to do that besides using the "Flash" Action which does not work for me as explained.

Following this guide (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_programming.html#gs-programming-cmd) leads to the same issue.

Hi Laurin,

Which is your VS Code version? Can you try flashing from the Command pallette, i.e. press Ctrl+Shift+P and then select "nRF Connect: Flash to Board" or "nRF Connect: Erase Board" or "nRF Connect: Erase and Flash Board".

Regards,

Priyanka

Using erase Board does nothing at all

Same issue as already described when using Flash or Erase and Flash.

But using erase in "Connected Devices" works.

When i use Run - Start Debugging its seems like the JLinkARM.dll is found.

Hi Laurin,

Could you make sure whether you have installed the M1 version or the Universal version of the JLink package? We specifically recommend customers to install the Universal version.

This seems to fix the issue. Thank you very much :)
