Dear Forum,

I have the following problem and I'd be very pleased if you could help me:
I have a LPC11C24 and programm it with a LPC-Link. I changed the usual crystal to an 25MHz, but I want to drive the whole thing still on 12MHz.

If I try to debug it, it seems to flash but then sticks to 97% with "launching: ConfiguringGDB" and doesn't goes on.

I attached my changes in system_lpc11xx.c with the most important parts mentioned below.
It would help me so much if you could have a look at it. At the moment I don't see any light at the end of the tunnel.

Best wishes
Max

I'm a little bit confused. So you want to use 12MHz IRC instead of your 25MHz crystal?

BTW:

#define SYSOSCCTRL_Val 1//0x00000000

is setting BYPASS = now PLL is expecting a clock signal (no crystal!!) at XTAL1. Do you supply that?

Probably your wrong PLL setup is running until PLL is trying to work (in SystemInit())...

while (!(LPC_SYSCON->SYSPLLSTAT & 0x01));      /* Wait Until PLL Locked    */

Thanks for your input! It already helped me finding some big mistakes but unfortunately the problem seems to stay the same.
As nothing seems to work at the moment, I wanted to run the controller with its internal clock, in the end it should run on 12,5MHz
For trying it with the internal clock, I chose the following preferences:
#define CLOCK_SETUP 1
#define SYSCLK_SETUP 1
#define SYSOSC_SETUP 1
#define SYSOSCCTRL_Val 0x00000000
#define WDTOSC_SETUP 0
#define WDTOSCCTRL_Val 0x000000A0
#define SYSPLLCLKSEL_Val 0x0000000
#define SYSPLL_SETUP 1
#define SYSPLLCTRL_Val 0x00000023
#define MAINCLKSEL_Val 0x00000003
#define SYSAHBCLKDIV_Val 0x00000001
#define AHBCLKCTRL_Val 0x0001005F
#define SSP0CLKDIV_Val 0x00000001
#define UARTCLKDIV_Val 0x00000001
#define SSP1CLKDIV_Val 0x00000001

I also uncomented the line you mentioned but it doesn't work. :((
Do you have some other ideas?

That's not possible. With your crystal you can run it with M*25MHz.That's 25MHz or 50MHz...

With IRC you can run it with 12 MHz...

Could be a good idea to decide which clock source and main clock you are trying to get...

The simplest solution is of course to select IRC...

Unfortunately I might didn't write it the right way. Of course the main clock should run on 50MHz or 48MHz.
Of course the internal clock is the easiest way but I'm not sure if it is precise enough to use CAN properly.
If that was possible it would be also much better for me, as I can reduce the size of my board. So IRC is actually my first choice.
I tried it with the internal clock but debugging is still not possible

Then you should switch SYSOSCCTRL FREQRANGE to 25MHz:

#define SYSOSCCTRL_Val        0x00000002

and use [color=#f00]M = 2[/color] to get 50MHz main clock:

#define SYSPLLCTRL_Val        0x0000002[color=#f00]1[/color]

That's all...

Nothing seems to happen :(( :(( :(( It still goes up to 97% and stops then
#define CLOCK_SETUP 1
#define SYSCLK_SETUP 1
#define SYSOSC_SETUP 1
#define SYSOSCCTRL_Val 0x00000002
#define WDTOSC_SETUP 0
#define WDTOSCCTRL_Val 0x000000A0
#define SYSPLLCLKSEL_Val 0x0000001
#define SYSPLL_SETUP 1
#define SYSPLLCTRL_Val 0x00000021
#define MAINCLKSEL_Val 0x00000003
#define SYSAHBCLKDIV_Val 0x00000001

What the hell do I do wrong? Flashing works fine but I want to debug!
Please help :((

Are you sure that your crystal is working?

Are you sure that your board is working? Did you ever flash and run a program successful?
