you just mentioned device sam4e8c..
are you using custom made dev board? or using sam4e xplained pro or sam4e-ek ?

if you are using sam4e xplained pro or sam4e-ek then device on board is sam4e16e.. probably thats what causing the signature mismatch..

I issue is resolved. I had to update a device pack manager for sam4e.
