ST91x IAR Ver 5.0 Port

Posted by johanan on August 29, 2007
Got IAR ver 5.0 (and not 4.x) and looks like startup file and vector file (91x_init.s, 91x_vect.s) of this port are not compatible. I tried to make the minor changes, but unfortunatly am very new to IAR and ARM programing, and no luck (cant get read of some linker error, and not 100% sure that I am doing the right changes).
can anyone help?

Richard - when is V5 support going to happen?

Version 5 does not yet support the Cortex M3 processors. When Cortex M3 is supported I will update the IAR projects to use V5.0. Until then I have not even looked at V5.

A new V4.x version was released at the same time as V5. This is what I upgraded to and am currently using.

I am tring to do it while learning the ARM9 assembler, so I probably make a lot of mess (but learning somthing).
I already got the led flashes but have the stack (both CSPR and SVC_SPR) inflating.
Is there is some document on how freeRTOS work at the low level of the ARM port?
