I want to in this post solve programer JLink error. I had not error with software JFlash v6.0.0.I have error with Keilv5. I too had same error with JFlashV6.12 . we know there are differenet version and clone of JLink in market. I used this method(changing driver JLink) , every thing is ok with Keilv5 and JFlash.
I unistalled current driver JLink that installed JFlash, and i update driver with driver of folders Keilv5. In Path of Keil Directory/Keil_v5/ARM/Segger/USBDriver you should update driver of JLink.

you can see work that i do in screenshots in win8.1.

I set debug mode on jlink, and i select device at91sam7s64,now every thing is ok,jlink in keil v5 and jflash can erase and programmed like charm. jlink is good debugger,but ulink debugger has less error …
I hope have good and cool days with atsam7s64. It is good point for starting ARM Microconroller Atmel Coporation.
best regards stackprogramer
