[ECOS] Re: Cortex-M3 interrupt handling & context switching

[Keith Ross]

Hi Simon,

Reading the Cortex-M3 Technical Reference Manual (DDI0337E) it certainly 
would be good idea to use the SVC instruction to cause a context switch. 
For those interested SVC is similar to SWI in other micros. The manual 
has a suggested method for context switch which we should follow. The 
eCos scheduler determines which thread to run and the ARM example code 
would switch it.
