Hello, sorry I am new in ARM
I use:
Olimex LPC2214
IAR Embedded Workbench Kickstart for ARM 5.10
FreeRTOS v4.4.0
Link with heap-3.c
Debug with Olimex Wiggler
I have CSTACK in [0x40000000 .. 0x40001000]
and the HEAP in [0x40001000 .. 0x40003000]
In the call to the function vPortStartFirstTask() I have this error:
"The stack pointer for stack 'CSTACK' (currently 0x400011EC) is
outside
the stack range (0x40000000 to 0x40001000)"
FreeRTOS creates the task stack in the memory HEAP, and SP is limited to
[0x40000000 .. 0x40001000]
I dont see the solution.
Any suggestions?
Thanks
Cristal Bell

Hi,
I'm surprised you got that far using V5.x. Currently all the projects are
setup for V4.x. There was a new V4.x version that was released at the same
time as their first V5.x project. I didn't use V5.x because it does not yet
support the Cortex M3, which is presumably the same reason they released a
new 4.x version too. When Cortex-M3 is supported then I will switch to use
V5.x for everything.
I don't know if it would help or not, but you could try using heap_2.c, and
setting the heap to zero in the linker script.
Regards,
Richard.

I would appreciate a copy of that myself. It might save me some time
porting over the V4.x projects. Can you send it to me on r _dot_ barry [at]
freertos.org. Thanks!

It's located here:
http://www.indyelectronics.com/freertos45.lpc2148.iar5.zip
Extract it over the FreeRTOSV4.5.0 folder.
Project is located:
