Hallo!

I have a Keil MCB2300 Eval Board with the LPC2368 and using the uVision3 Eval Version with a uLink2 JTAG Adapter.

So, theres no port for my Hard- & Software, and I do not now where to start now…

Can someone give me a few hints?

Thanks.  
Dominik

Does your uVision come with the old Keil or RealView compiler.&nbsp; If the former than you can start with the existing LPC2129 Keil demo and convert this for the MCB2300.&nbsp; I think there is a small change required in the port.c file when setting up the timer between the LPC2129 and LPC23xx, should be straight forward.&nbsp; If you are using the RealView tools then there is not a project in the download (why not?), but if you email Richard he can send you an ARM7 RealView project which you would then havet to convert to be LPC23xx specific.&nbsp; 90% of the code is the same between all the ARM7 ports, only the timer, startup code and interrupt controller configuration differs.

I have the Eval Version of uVision3 that was shipped with the MCB2300.  
I think it uses GCC (?), I installed Cygnus Tool with GCC also.

What I managed to do is to compile the LPC2106 Demo for GCC with GNUARM and UnxUtils.  
So I have no problem using GCC.

So you say I have to adapt Timer, Startup and Interrupt Stuff.  
So first I have to modify boot.s.  
I would like to use the startup code from the LPC\_2368 Rowley Demo Project. But I can’t find it…

Hi there,

The startup code for the LPC\_2368 Rowley Demo Project, lies in the package folder  
og rowley crossworks IDE, thats why it isn’t present in the demo folder.

regards,  
Martin
