The following comment is on a website for the pC/OS RTOS kernel (http://www.embedded-os.de/) The port of the pC/OS Kernel on AT91SAM7Sxx is now finished. As Toolchain the IAR Embedded Workbench was used. Sorry to Keil, with "...?T" and "...?A" it's not really possible to create a good port for ARM and Thumb mode. If anyone knows what this means, will you please explain it? Thanks.
... more tests using the simulator and the board... Following test was running on the board: * If I set a breakpoint at
bl AppTickInit(0x00101290) - Part #1
push {r4-r5,lr}

The CARM compiler handles all the interworking automatically. As usual with software, there is always the chance to get into some 'notch'. You should provide a boiled down example since the code fragments simply don't give enough details. Your most recent post looks like a stack overrun/underrun problem. Peter
