jlink-3.78c - w/gdbserver - dies a horrible death and goes 'ker-plop'


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
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

License GPLv3+: GNU GPL version 3 or later <>
This is free software: you are free to change and redistribute it.

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.

Hello duane,

we will investigate this problem.
You are right, in order to reproduce the problem it would be useful to have the .elf file.
Can you please send the .elf file to the e-mail address which I will send you via PM?

Hello Duane,

We have built a new beta version of the J-Link GDB Server
which can generate a detailed logfile.

The new beta version is available for download from our website:

Can you please download this version and
send us the GDB logfile ?

To generate a GDB logfile please enable the
"Generate logfile" checkbox in the GDB Server

You will find the logfile in the program folder of
the GDB Server. It is named "JLinkGDB.log".

Best regards,

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