I would like to programm and debug a nxp lpc2388 on a mcb2300 board. Right now i am using following programms/drivers: Windows XP SP3 Eclipse Galileo including Zylin CDT Yagarto 4.4.2 openOCD 0.3.1 (installer Version from http://www.freddiechopin.info) libusb win32 I am (more or less?) successful at compiling my sourcecode and connecting openocd to the Olimex-arm-usb-ocd. I start opencd as an externaltool (within eclipse) with the follwing arguments:
1 | -f .../target/lpc2378.cfg |
2 | -f .../interface/olimex-arm-usb-ocd.cfg |
So far the part that seems to work, if i connect Openocd i get the following Output in the console:
1 | Open On-Chip Debugger 0.3.1 (2009-11-13-16:13) |
2 | $URL$ |

Except for the last Line everything looks ok. Unfortunately i have no idea how to solve this problem, but actually do not think its my main problem. As soon as i start arm-elf-gdb using the following arguments:
1 | target remote localhost:3333 |
2 | monitor sleep 500 |
3 | monitor poll |
4 | monitor flash probe 0 |
5 | monitor flash info 0 |
6 | monitor soft_reset_halt |
7 | monitor flash erase_sector 0 0 0 |
8 | monitor flash write_image main.bin 0x0 |
9 | monitor reset run |
10 | monitor sleep 500 |
11 | monitor soft_reset_halt |
12 | symbol-file main.elf |
13 | info mem |
14 | thbreak main |
15 | continue |
I see different "Versions" of behaviour. Unfortunately it just doesnt work no matter which version i see. Most of the time it looks like this:
1 | Warning: /cygdrive/D/workspace/merses/LCD/.dep: No such file or directory. |
2 | Warning: /cygdrive/D/workspace/merses/LCD: No such file or directory. |

Allthough the flash seems to be protected, the Flash is erased successfully und filled with my programm. Allthough i dont know how to get rid of this wrong checksum. Another Version contains this behaviour:
1 | monitor soft_reset_halt |
2 | requesting target halt and executing a soft reset |

Either way it just freezes at "continue" and i dont have a chance to do anything. I have tried to get this to work for a long time now. What confuses me the most: with the same software and Configuration it works on another pc. There i also have this "Error: EmbeddedICE v7 handling might be broken" as well as the "wrong checksum" Error, but debugging perfectly works. Right now i am completely out of ideas and feeling really desperate. I really hope that someone here can help me. Thank you in advance
