KEIL4 "No Jlink device found".

[muhkuhns]

I have a nRF51-DK and SDK8+Keil5. I also have a module that sadly uses an old revision 1 nrf51822. It is connected via SWD to my nRF51-DK.

I could programm it with keil 5. I can programm it with nrfgo studio.

But to use SDK5 I have installed KEIl4. And this gives me the titled error now when I try to flash a example...

Well that was easy. Hitting Repair on nrfTools after installation of Keil4 solved the problem!

Very sorry about the thread dig (mods please feel free to delete and reprimand me):

For anyone else coming across this issue through Google search, it seems there's something weird about the JLink DLL that comes with different versions of Keil. Managed to fix by installing the JLink tools directly from Segger

Let the installer overwrite the Keil DLL, run the JLink Commander app and let it do any firmware updates it wishes. Keil should then see it fine.
