After seeing the instruction, I downloaded the Keil development kits,but it seems not to work with Keil port(I mean Philips ARM7 with the Keil development tools). So could you give me a updated version of this port, I will be very appreciate for the help. PS: the problem now is when I tried to build target of the project, the development kit displayed the error message:can’t execute ‘C:\Keil\ARM\BIN\CA’ Thanks a lot ---

Send me an email to r (dot) barry [at] [freertos.org](http://freertos.org), and I can send you a third party demo that was created for the Keil/ARM combo. Regards. ---

Can I help somehow? If the "third party demo" mentioned is the one I sent to Richard, here is a correction to make in the sam7.s file: \_\_user\_initial\_stackheap                 LDR     R0, =  Heap\_Mem                 LDR     R1, =(Stack\_Mem + USR\_Stack\_Size + SVC\_Stack\_Size)    ; start in SVC mode!                 LDR     R2, = (Heap\_Mem +      Heap\_Size)                 LDR     R3, = Stack\_Mem                 BX      LR (It works anyway, but the stack sizes will be mixed up if this is not fixed.)

The Keil/ARM debugger (whatever it is called now) has a major disadvantage in that the evaluation edition only permits a total data size (ROM + RAM) of 16K.  This limits the heap size that can be allocated unless using the full version.  The Cortex M3 Keil demo gets around this by allocating the heap simply as a pointer at the end of the data section (this was an idea sent in by a contributor, maybe you?) rather than as an array.  This gets around the data size limit but means there is no warning if you run out of heap, unless you change the heap\_x.c files to have an absolute memory check. I would be grateful if you could send me the zip file again with the above fix included to make sure I have everything straight.  I appreciate your contribution to the project. Regards. ---
