Posted on August 10, 2006 at 04:09I have My Own STR710 develope board.
I follow the AN1710 from micrium to port uC/os to my board in RAM mode.
But I confused that linking with STR710-RAM.xcl ,the board doesn't work.
maybe timer0 doesn't work,because I add some test code in bsp_init() and it's work ok.
It is not Task switching.
the code in Bsp_Init()
{
...
BSP_IRQ_VECTOR_ADDR = 0xE59FF018; /* LDR PC,[PC,#0x18] instruction */
BSP_IRQ_ISR_ADDR = (CPU_INT32U)OS_CPU_IRQ_ISR; /* IRQ exception vector address */
BSP_FIQ_VECTOR_ADDR = 0xE59FF018; /* LDR PC,[PC,#0x18] instruction */
BSP_FIQ_ISR_ADDR = (CPU_INT32U)OS_CPU_FIQ_ISR; /* FIQ exception vector address */
BSP_UNDEF_INSTRUCTION_VECTOR_ADDR = 0xEAFFFFFE; /* Jump to itself */
BSP_SWI_VECTOR_ADDR = 0xEAFFFFFE;
BSP_PREFETCH_ABORT_VECTOR_ADDR = 0xEAFFFFFE;
BSP_DATA_ABORT_VECTOR_ADDR = 0xEAFFFFFE;
BSP_FIQ_VECTOR_ADDR = 0xEAFFFFFE;
...
}
doesn't work.
Could you tell me why?
