[AVaRICE-user] Remote communication error

[István R. <ist...@gm...>]

Sorry for being so newbie, but still have some trouble.

I set succesfully the debugwire fuse
avrdude -F -c jtag2isp -P usb -B 10 -b 115200 -p t45 -e -U 
flash:w:myfile.hex -U lfuse:w:0xe2:m -U hfuse:w:0x9f:m -U efuse:w:0xff:m

... then start avarice
avarice -2 -j usb -P attiny45 -w --erase --program --file gdbinit-myfile 
localhost:4242 &

... then start avr-gdb
avr-gdb -x gdbinit-myfile

... and it becomes to operate, but exits with an error message:
...
...
Connection opened by host 127.0.0.1, port 58268.
0x00000000 in __vectors ()
Loading section .text, size 0x230 lma 0x0
jtagWrite(): numByte does not match page size
gdbinit-myfile:3: Error in sourced command file:
Remote communication error.  Target disconnected.

The content of gdbinit-myfile is:
file myfile.out
target remote localhost:4242
load
break main
continue

What do I still do wrong?
