ARM Keil IDE had asked me several times to upgrade J-Link firmware before starting a debug session. I ignored the pop-up window several times and all projects built and debugged ok. I finally allowed the firmware update suggestions and it seemed to upgrade fine (100% complete, no errors), but now when I attempt to do a program/debug session I get a "No J-Link found" error.
Is there a way to restore the default J-Link firmware or a download and associated method to allow programming/debugging on this hardware? I don't have any external J-Link programmer/debugger to reflash anything so I suppose the USB kit is now useless?
