Hello,
I am using nRF Connect for Desktop v3.12 and nRF Programmer V3.0.4
The programmer application just does not see the J-Link device, however your other apps like Bluetooth low Energy does see it (example bellow):
Also visual studio code does also see the nrf device with J-Link (example bellow):
Can someone help me to understand why I cannot see J-Link on the Programmer APP?
P.S. The unknown device shown by nrf programmer IS NOT J-Link
Hmm, I did that, still cannot see J-Link in Programmer application:
Still no luck:
Is there any other way to check whether something is flashed into nRF MCU? Basically we're solving issue in production and trying to figure out whether Nordic MCU has bootloader flashed and I remember I used to be able to check memory in this app before, but now it cannot even find J-Link.
Hi,
Is this a DK or a custom board? If it is custom, does the device have an on-board debugger? If it does not have an onboard debugger, then it will not show up in the Programmer unless you are using an external debug probe, or it is in bootloader mode.
You can also try using nrfjprog --readcode to read out the code and store it in a path, see nrfjprog commands. This will provide you with a hex file where empty parts will be filled with F:
While non-empty parts will look more like this:
This does not work if readback protection is enabled.
Best regards,
Marte
