JLINK-GDB - has support for hardware instruction breakpoints, the CI, BI, commands.
What about a DATA WRITE breakpoint?
What about a DATA READ breakpoint?
In my case, I have a nasty NULL pointer bug somewhere in my code. It trashes my interrupt vector table located at zero.
When that happens, well - bad things happen.
It would be *GREAT* to be able to set a write breakpoint at address ZERO and see what is trashing my vector table.
How do I do that with Jlink-GDB-SERVER?
Thanks.

Thanks - For those who do not know - the new beta version (379g) fixes the problem.

Last night - I emailed the ELF + two copies of the log file to the address you sent privately and forgot to put a note here.
Thanks.

Hello,
there are problems with the new version of jlink software. It crashes and exits. 
I have:
SEGGER J-Link GDB Server V3.78c
JLinkARM.dll V3.78c (DLL compiled Dec 13 2007 20:28:39)
J-Link connected
Firmware: J-Link compiled Dec 03 2007 17:15:31 ARM Rev.5
Hardware: V5.20
S/N: 20002799
OEM: SAM-ICE
Feature(s): RDI
Listening on TCP/IP port 2331
J-Link found 1 JTAG device, Total IRLen = 4
JTAG ID: 0x3F0F0F0F (ARM7)
SAM-ICE found !
I am using this version of GDB (from linux, gdbserver is running on my windows PC)
Using GDB (insight) 6.7.1 -
GNU gdb 6.7.1

This GDB was configured as "--host=i686-pc-linux-gnu --target=arm-elf".
From GDB, I can *CONNECT* to the board.
However, if I attempt to "download" - I get 2 or 3 messages then it dies/crashes/whatever - the GDBServer goes away, it dies very fast - I cannot tell if there are 2 or 3 messages. The previous version V 3.68B - works, and does not have this problem.
The "log" file it creates useless, and does not contain anything meaningful.
It shows the two write packets - to memory, and ends.
I am sure you want the elf file to try your self, who should I send it to?
Target is atmel at91sam7ex256.
-Duane.
