Uninstalling Keil completely

M AV

Hi all,

I had a project which I could successfully programto my NXP uC using a J-link. When I upgraded my Keil version I could not upload it anymore (erase failed error). I tried downgrading Keil version to 5.12 (which worked previously) and I keep getting the error.

I'm able to program the same project using other computer so the problem should be in some config file. I tried uninstalling it and installing it again deleting all files left in AppData and keil_v5 folders and also the what I could find in Windows key registry and still didn't get it working.

Is there something else I need to remove to completely uninstall it?

Regards,

Mikel

    Hi Miguel,
    that's hard to say. When you reinstall an older version of uVision, all MDK files get replaced. A newer J-Link driver might have updated the firmware of J-Link. As far as I know, you have another PC which can still program the LPC1820. You can try the same J-Link to see if the firmware makes a difference.
    Are you using a 'Init File' for flash programming (Options for Target - Utilities - Init File) if if yes, is it the same one?
