I use a raspberry pi with avrdude (avrdude version 6.3-20160220 (compiled) and 6.1 (from package) tested) to program a atmega128rfa1. I am currently using a AVRISP mkii but because it is unavailable I am looking into using the Atmel-ICE programmer.

I have some funny behavior with the Atmel-ICE programmer (avrdude 6.1 and 6.3). When I try to burn the fuses I get a verification error of the efuse (I want it to be 0xfe and 0xf6 is written). When I use the AVRISP mkii I can burn the fuses with avrdude 6.1 but not with 6.3 (verification error).

I think it is a simple bit masking error. The extended fuse only has bit 0,1,2 user configurable bit 3 has a description “Do not modify” with the default value of 1.

Command (avrdude 6.1):
avrdude -p m128rfa1 -c atmelice_isp -P usb -B 32 -U lfuse:w:0xf7:m -U hfuse:w:0xd1:m -U efuse:w:0xfe:m

Output (only the error part):
avrdude: verification error, first mismatch at byte 0x0000 0xf6 != 0xfe
avrdude: verification error; content mismatch

When I use the old and trusted AVRISP mkii with avrdude 6.1 everything works
Command (avrdude 6.1 only, 6.3 give the error above):
avrdude -p m128rfa1 -c stk500v2 -P usb -B 32 -U lfuse:w:0xf7:m -U hfuse:w:0xd1:m -U efuse:w:0xfe:m

avrdude: 1 bytes of efuse verified
