LPC1768 Debug with Olimex ARM-USB-TINY-H + Eclipse + Zylin

Development Boards MicroMod

Hi,

I bought a JTAG adapter from Olimex (http://www.olimex.com ARM-USB-TINY-H) for my LPC1768 Board (own design) to flash and debug it. I spent days to find the correct makefile & project.cfg to compile and flash the firmware. This works fine. But I dont know how to configure the Debug GDB Config under Eclipse. Although I have found a few tips and lines of code, but it still does not work :(. In the lpc1768.cfg file in openocd-0.6.1\scripts\target\ I changed “CCLK” to 96000 (set up in system_LPC17xx.c).

On the pictures are the config settings. I tried differnt Init & Run Commands with different error messages. Nothing works. Can someone help me?

The project files:

The Run config for Eclipse:

project.cfg for flashing the firmware:

project2.cfg for only connect (and then debug):

Ok I answer myself:

I put these commands into my project.cfg file:

init
sleep 200
reset init
halt
wait_halt

so my entire project.cfg:

# project file for Debug Sessions

source [find target/lpc1768.cfg]
reset_config srst_only

adapter_khz 500

init
sleep 200
reset init
halt
wait_halt

In the Init/Run fields of GDB/Debug Config I wrote these lines:

target remote localhost:3333
load

stepi
break main
continue

Now I get these Output:

source .gdbinit
target remote localhost:3333

load

Note: automatically using hardware breakpoints for read-only addresses.
stepi ignored. GDB will now fetch the register state from the target.

Program received signal SIGINT, Interrupt.

continue

Breakpoint 1, main () at main.c:29
29		LPC_GPIO1->FIODIR |= 1 << 29; // P1.29 connected to LED

And everything works! :slight_smile:

Hi, ottelo,

can you tell me if JTAG adapter will run in such environment: http://www.encryptedfilestorage.com/zer … he-clouds/?
