Forgive me the stupid question, and thanks Manus for the kind reply :)
I had to replace a few LM3S6611(problem) with LM3S6965(work fine)
because I neet to ship some boards this weekend :(
My real problem still persists with LM3S6611: I can access the chip via
telnet, I can write to the flash and the messages is just fine, but
nothing get to the flash (it is not written)
I guess that *I will need to debug this mself*, but please, I need help
with basic information: where is the flash writing program, how does it
interface with OpenOCD, ets...
Here is what I get when writing to flash:

then I open OpenOCD agin and I display the flash memory it is not correct!!!
Just for reference I attached my config file
Please help

Hi, I just changed my Cortex-M3 from LS3S6965 to ML3S6611 and it
stopped working :(
When I start openocd (0.2, Linux, FTD2232) I get:

=> I checked and the device code is exactly the same for both chips!
Using telnet, if I display memory I get:
> mdw 0 8
0x00000000: 20000010 00000021 0000000d 00000029 00000045 00000045
00000045 00000000
> mdw 20000000 8
Maybe it should be (hexadecimal)
mdw 0x20000000 8
Sticky errors is almost always trying to acces nonéxisting memory.
Best regards,
