I have tested Keils RTX Program EX1.c using Lpc2124 using the Debugger and everthing ran OK.
So I modifed the EX1.c Prog for the LPC 2368. 1) Used LPC23xx.h through-out. 2) Removed Startup.s and used lpc2300.s and modifies the SWI Handler as described by Keil. 3) set T1TCR to 0 before os_init.
Started the Debugger and displayed OS-Support-> rtx-kernel it shows: task 1 wait_or " " 0000 0004 36% (ie no delay is shown, wait for event) task 2 wait_delay 2 " " " " 32% (ie no events expected) idle_os_demon 0%
There is no task switching going on.
Looking at Clock dividers the CCLK regularly changes from 48 to 2 MHz and back again...and this appears to me ti be wrong, but cannot find out why. I have a suspicion that the reset handler is being called.
I'm using the Keil Demo V4 uVision on Win XP.
Can any one help me out to locate the problem?

lpc2300.s is the correct startup code -- supplied by Keil! The Debugger shows that the SWI interrupts used by the RTX work. The original LPC 2164 startup.s does not work with the lpc2368.
There is no such thing as the - ie, one and only - correct startup code!
What Keil provide gives you a basis from which to start in developing something that is appropriate for your particular application - they clearly cannot provide a single file that is "correct" for every possible application!
So, you need to check this lpc2300.s and see if it does everything that is needed for your particular application
