The demo application compiles fine. Downloading the code to the board generates the following messages: Info:    openocd.c:92 main(): Open On-Chip Debugger (2007-08-17 11:00 CEST) Info:    target.c:232 target\_init\_handler(): executing reset script ‘program.script’ Info:    configuration.c:50 configuration\_output\_handler(): requesting target halt… Info:    configuration.c:50 configuration\_output\_handler(): waiting for target halted… Info:    configuration.c:50 configuration\_output\_handler(): target halted Warning: stellaris.c:379 stellaris\_read\_part\_info(): stellaris flash only tested for LM3S811 series Info:    configuration.c:50 configuration\_output\_handler(): flash ‘stellaris’ found at 0x00000000 Info:    configuration.c:50 configuration\_output\_handler(): #0: stellaris at 0x00000000, size 0x00020000, buswidth 0, chipwidth 0 Warning: stellaris.c:379 stellaris\_read\_part\_info(): stellaris flash only tested for LM3S811 series Info:    configuration.c:50 configuration\_output\_handler(): Info:    configuration.c:50 configuration\_output\_handler(): LMI Stellaris information: Chip is class 3 Unknown part vA.0 Info:    configuration.c:50 configuration\_output\_handler(): did1: 0x1049400d, arch: 0x1049400d, eproc: ARMV7M, ramsize:64k,  flashsize: 128k Info:    configuration.c:50 configuration\_output\_handler(): master clock(estimated): 22500kHz,  rcc is 0x78e3ad1 Info:    configuration.c:50 configuration\_output\_handler(): pagesize: 1024, lockbits: 64 0xffffffff, pages in lock region: 2 Info:    configuration.c:50 configuration\_output\_handler(): Info:    configuration.c:50 configuration\_output\_handler(): sector number(s) invalid Warning: target.c:562 target\_alloc\_working\_area(): not enough working area available Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x0, 20724 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x1000, 19700 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x2000, 18676 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x3000, 17652 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x4000, 16628 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x5000, 15604 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x6000, 14580 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x7000, 13556 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x8000, 12532 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x9000, 11508 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xa000, 10484 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xb000, 9460 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xc000, 8436 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xd000, 7412 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xe000, 6388 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0xf000, 5364 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x10000, 4340 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x11000, 3316 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x12000, 2292 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  1024 words to 0x13000, 1268 remaining Warning: stellaris.c:686 stellaris\_write\_block(): Algorithm flash write  244 words to 0x14000, 244 remaining Info:    configuration.c:50 configuration\_output\_handler(): wrote  82896 byte from file ./RTOSDemo/RTOSDemo.bin to flash bank 0 at offset 0x00000000 in 13s 356000us (6.061180 kb/s) The debug server starts fine, but I get this error when I try to launch the demo in a debugging session.

Second, openocd\_ftdi is configured to start listening to port 3333 but gdb is configured to connect to port 10000.  I changed gdb to 3333 and was able to start a debugging session. However, I cannot step, hit breakpoints, or really do anything with the debugger.  I am seeing errors like these from openocd: Info:    server.c:67 add\_connection(): accepted ‘gdb’ connection from 0 Error:   cortex\_swjdp.c:224 swjdp\_transaction\_endcheck(): SWJ-DP STICKY ERROR Error:   cortex\_swjdp.c:238 swjdp\_transaction\_endcheck(): dcb\_dhcsr 0x30003, nvic\_shcsr 0x20000, nvic\_cfsr 0x10000, nvic\_bfar 0xe000edf8 Error:   cortex\_swjdp.c:224 swjdp\_transaction\_endcheck(): SWJ-DP STICKY ERROR Error:   cortex\_swjdp.c:238 swjdp\_transaction\_endcheck(): dcb\_dhcsr 0x30003, nvic\_shcsr 0x20000, nvic\_cfsr 0x10000, nvic\_bfar 0xe000edf8 Thanks, Marc ---

I have exactly the same problem with CodeSourceryG++ 4.4-104 and a custom board with LM3S9B90. Any help would be very much appreciated. Kind Regards, cee
