Hi I have just received my GSB server and I still can't use it

I have a DK-LM3S9B96 with the FTDI ICDI Interface on the board I debug and download without problem but

Why I can't debug with my J-LINK GDBServer ???

here you can see my log :



SEGGER J-Link GDB Server V4.12

and I use the following instructions (those mentionned in the user guide for Cortex M3) :



target remote localhost:2331
monitor speed 1000
monitor flash device = LM3S9B96
monitor flash cpuclock = 16000000
monitor flash breakpoints = 1
monitor flash download = 1

load C:/Dev_LUMINARY/B96/StellarisWare/boards/dk-lm3s9b96/blinky/gcc/blinky.axf
monitor reg r13 = (0x00000000)
monitor reg pc = (0x00000004)


Furthermore the chip doesn't seems to be programmed
What's wrong ??

Hi, all

if you have the same problem you just have to put "little endian" instead of "big endian" in the combo box of the SEGGER J-Link GDB Server V4.14 window

you know what I am happy
