ARM CortexM3 PORT
ARM Cortex M PORT
This folder contains a port of the Atomthreads real time kernel for the
ARM CortexM3 processor architecture.
ARM CortexM type processor architecture. This port was tested on the
Cortex M3 and the Cortex M4.
To Use:
1. Install the "pendSV_Handler" and "tick_Handler" implemented in the file
"atomport_arm.asm" in your platforms interrupt vectors.
2. Complete the function "archTickInit()" implemented in "atomport.c" to
initialize your platforms timer tick interrupt. If you use the build in
SysTick of the CortexM3 you also have to add code here to start it.
3. If required, add code to acknowledge your timer hardware's interrupt in
the function "archTickHandler()" also implemented in "atomport.c".
4. During your platform initialization call the function "archTickInit()"
exported from "atomport_private.h" to initialize the CortexM3
"PendSV_Handler".
5. After your platforms c-runtime initialization has completed, start
Atomthreads from your runtime's "main()" function.
See the example project in the "platforms/qemu_lm3s" directory.
