[avr-chat] Problems fuse programming Atmel-ICE

[Armin Oonk]

Hi,
 
I have a small programming setup for a custom pcb. I use a raspberry pi with avrdude (6.1) 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. When I try to burn the fuses I get a verification error of the efuse
Command:
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 everything works
Command:
avrdude -p m128rfa1 -c stk500v2 -P usb -B 32 -U lfuse:w:0xf7:m -U hfuse:w:0xd1:m -U efuse:w:0xfe:m
 
Output:
avrdude: 1 bytes of efuse verified
 
 
Does anybody have a idea why it get an error with the atmel-ICE programmer?
 

Full command output:

sudo avrdude -p m128rfa1 -c atmelice_isp -P usb -B 16 -U lfuse:w:0xf7:m -U hfuse:w:0xd1:m -U efuse:w:0xfe:m

Would you like this fuse to be changed back? [y/n] n
avrdude: safemode: Fuses OK (E:FE, H:D1, L:F7)

avrdude done.  Thank you.
