I'm using a jLink Lite Cortex- v8.00. After some software updates (windows updates, changed the IAR license with a dongle license) the flashing/downloading stopped working. The error in jlink.exe is related to the following code: 0xC0000005 (unhandled exception at 0x0A0D6B6E).



A similar error I received in IAR embedded workbench:
“Mon Feb 27, 2017 08:16:01: IAR Embedded Workbench 7.70.2 (armproc.dll)
Mon Feb 27, 2017 08:16:01: Loaded macro file: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.5\arm\config\debugger\NXP\KW2xD.dmac
Mon Feb 27, 2017 08:16:15: Fatal error: Unknown exception in driver 3 Session aborted!
Mon Feb 27, 2017 08:16:16: IAR Embedded Workbench 7.70.2 (armproc.dll)”

I tried to reinstall IAR and different versions of Segger Firmware (6.12i, 6.12j, 6.14), but with no improvement.


Any suggestions would be appreciated.

Hi Nino,

Thanks for the reply. I validated the setup using a secondary PC and everything works fine.
As you mentioned, it is hard to replicate, so probably I will need to do some windows recovery stuff.

Thanks anyway,
Ovidiu
