Hi,
I'm working on a new driver for openOCD. I'm ready to test it with an
ATMEGA 128.
Here is my config file : (bvsjtag is my driver ;) ).
debug_level 3
#daemon configuration
telnet_port 4444
gdb_port 3333
source [find interface/bvsjtag.cfg]
reset_config trst_and_srst
source [find target/mega128.cfg]
The AVR is well recognized, the IDCODE read by the driver is correct.
I'm having some problems by launching gdb.
Here is the openOCD log :

To launch GDB, I do :
$ avr-gdb
GNU gdb 6.4
This GDB was configured as "--host=i486-linux-gnu --target=avr".
(gdb) target remote localhost:3333
Remote debugging using localhost:3333
Ignoring packet error, continuing...
Reply contains invalid hex digit 116
(gdb)
Telnet connection seems to work...
I developped my driver on OpenOCD 0.4.0
If someone could help me ? Google didn't give me an answer...
