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.
thanks, but see the main.c - AppTickInit() is a C-function called from main(). I think, this is to handle by the compiler... Have the Keil-compiler optimizing problems with not direct called functions (see Task1..3) or problems with C-Thumb-code mixed with ASM-Thumb/ARM-code ? Frank
... Sorry ! see the main.c - AppTickInit() is a C-function called from C-function Task1(). But the problem is still the same...
... 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}
B530 push {r4-r5,lr} 2500 mov r5,#0x00 2400 mov r4,#0x00
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
