[avr-chat] avrdude doesn't write lock bits with JTAG ICE mkii on 328P target

[Daved]

I'm trying to use avrdude to write the lock bits and fuses on a 328P with a JTAG ICE mkii. Here is the command:

 

"C:\Program Files\arduino-0017\hardware/tools/avr/bin/avrdude" "-CC:\Program Files\arduino-0017\hardware/tools/avr/etc/avrdude.conf" -v -v -v -v -pm328p -cjtag2isp -Pusb -e -Ulock:w:0x3F:m -Uefuse:w:0x05:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m

 

It tries to write the the lock bit but fails the read back verification.

 

According to the avrdude doc "Only the memory programming functionality of the JTAG ICE is supported by AVRDUDE".

I have a few questions regarding this:

1. Is this limitation for the mkii as well?

2. Since the JTAG ICE mkii is capable of programming the lock bits and fuses (I can do it with AVR Studio), why isn't this functionality supported in avrdude?
