Hi guys, i bought a MOD-LCD4.3 from Olimex with a LPC1788 Cortex-M3 processor (https://www.olimex.com/Products/Modules/LCD/MOD-LCD4.3’') and a ARM-USB-TINY-H Debugger because i want to learn a little bit about ARM-Cortex processors and openocd. I am using openocd 0.6.0 under Ubuntu 12.04.
I can start openocd and get the following output
openocd -f olimex-arm-usb-tiny-h.cfg -f lpc1788.cfg

adapter speed: 10 kHz

Info : JTAG tap: lpc1788.cpu tap/device found: 0x4ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x4)
I think this means that the jtag connection is ok. Please correct me if i am wrong. Now i want to debug a simple application which i compiled with a own startup code and linker script.
But when I start gdb i get the following output
arm-elf-gdb target.elf
(gdb) target remote localhost:3333
localhost:3333: Connection refused.
I would be very greatful if someone could tell me how i can figure out where the problem is. I am very desperate because i am trying to connect to the cpu for 3 days now. And I want to apoligize for my bad english, thats my first post in an english forum. I hope you can help me.
