JLink gdb server launching fails from KDS but not from command line

[mike1974]

Hello everyone,

I get this error when trying to launch my debugger from the flash configurations window...

Error while launching command C:\Program Files\SEGGER\JLink_V496b\JLinkGDBServerCL.exe -if swd -device MK22FN1M0xxx12 -endian little -speed 1000 -port 2331 -swoport 2332 -telnetport 2333 -vd -ir -localhostonly 1 -s

Cannot run program "C:\Program Files\SEGGER\JLink_V496b\JLinkGDBServerCL.exe": Launching failed

However if I go to the command prompt and paste the same command, it seems to be ok...

...

Connecting to J-Link...

JLinkGDBServer.exe is a Win32 executable, and therefore you need to launch it correctly (as a windows binary). You cannot launch binaries/executables from normal eclipse views.

If you want to launch binaries, have a look at things like WickedShell (5 Best Eclipse Plugins: #5 (WickedShell) | MCU on Eclipse) or simply launch it as 'external tool'. I use that approach e.g. to launch the explorer.exe, see http://mcuoneclipse.com/2014/11/24/adding-show-in-windows-explorer-to-eclipse/

I hope this helps,
