First of all, I am a Korean student and I am not good at English, so even if the translation is weird, let's move on.
I brought ATSAM4LS4A and connected it as follows 
Oh, and please ignore that oscillator He's using an internal oscillator anyway. Maybe? I didn't touch the fuse beat
And I tried programming after building without code in atmel studio, and the following error occurred
(Erasing device failed)
If I skip the erasing step and try,
(Failed to write segment at 0x0 targert for memorytype base)
I can read fuse bits and HEX files in flash memory, but I can't write fuse and HEX
(WriteRegister() failed to write at 800004)
How do we solve these errors?
And is this error caused by not properly understanding the data sheet?
