Problem Porting nucleus onto AT91RM9200
psriniva - 2006-05-24 10:57:00
Hi,
I am trying to port Nucleus Kernel onto the AT91RM9200 Target (on Cogent
CSB337) using Nucleus EDGE IDE. I am facing some problem with the Stack
handling especially while servicing the interrupts.
Has anyone been able to successfully prot Nucleus RTOS onto AT91RM9200?
Please let me know.
