since a few days i try to set up a SDK to program a NXP1768 (ARM LPC1768
Cortex M3 LCD Board from Steitec)
in combination with a J-Link EDU.
The first test was with the open source option --> Yagrato + Eclipse
I've done every step in the yagarto tutorial. I started a new project
and imported the example LPC1768Test from the yagrato download section.
The first thing i noticed, was that eclipse dont find typical c
hedaers, for example the stdint.h, but i could successfull build the
The next thing i wanna do is to use the debugging function in
combination with the J-Link, so i followed the tutorial to configure the
At configuration point where you have to copy in the Initialization
Commands, I ve included the folowing two listings:
# connect to the J-Link gdb server
target remote localhost:2331
# Set gdb server to little endian
monitor endian little
# Set JTAG speed to 1000 kHz
monitor speed 1000
# Reset the target
monitor sleep 100
# Set JTAG speed in khz
monitor speed auto
# Vector table placed in RAM
monitor writeu32 0xE000ED08 = 0x10000000
monitor reg r13 = (0x10000000)
monitor reg pc = (0x10000004)
After that i started the Segger GDB Server (I use Version 4.42a), an now
all things are connected. The problem
no target connected (red symbol), but i see a target voltage (3,27 V
green symbol) an the Jlink connected (also green symbol).
What is my mistake?
Then i start debugging and the GDB Server connects to the target (all
symbols are green), but i could not step to code an error occures.
"Execusion is suspended because of error" What is wrong?
After that frustrating tutorial, i only wanna to find out how i could
flash the nxp.... just a simple blinking led code...please!
So the next option I've choosen, was a trial version of IAR Embedded
Workbench (btw: V 6.30.2) in combination with J-Link EDU.
I started with a little test project for GPIO usage.
Here the source...
int main (void)
uint32_t i, j;
//LED = P2[0..7]
LPC_PINCON->PINSEL4 &= ~(0xFFFF); // Reset P2[0..7] = GPIO
LPC_GPIO2->FIODIR |= 0xFF; // P2[0..7] = Outputs
LPC_GPIO2->FIOCLR = 0xFF; // Turn-OFF all LED
//Loop LED Test
for(i = 0; i < 8; i++)
LPC_GPIO2->FIOSET = 1 << i;
for(j = 1000000; j > 0; j--);
LPC_GPIO2->FIOCLR = 0x000000FF;
for(j = 1000000; j > 0; j--);
I got errors in the lines the pins are reseted an set as output.
"identifier LPC_OINCON is undefined",
okay propably defined in th header! Where do i get this header, from
NXP,or is it a part of the IAR workbench, because i have to choose the
And how could i add it to the project?
Could i set the port directly, without any definition?
Like you can do it with AVRs, like this ???
PORT2 |= 0xFF;
The last thing i did, was to install a trial version of Keil u Vision,
i started a new project ...again and build it and all went well until i
press the load button, then an error occures
here is the log file:

so far thats it. I would be very happy if you could help me in this
with best thanks,
