PSoC4 SysTick interrupt

[Anonymous]

SysTick feature is supported in Cortex M0 and hence can be used in PSoC4 as  system tick interrupt to control task switching.     

       

SysTick is Cortex Vector #15. System API functions CyIntSetSysVector() and SysTick_Config() have to be used to initialize the SysTick and control its frequency

Could You point me where NVIC memory excactly is:

   

CM0 heder points to SRAM address where NVIC table is located

   

My systickirq function has address 0x0000056c

   

But when I look in SRAM where NVIC should be located :

   

cyisraddress *ramVectorTable = (cyisraddress *) CY_INT_VECT_TABLE

   

CY_INT_VECT_TABLE = 0x20000000 (SRAM_BASE)

   

But the contents of this table is null. No pointers to to ISR functions I've declared:

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

0x20000000	00	10	00	20	9b	00	00	10
0x20000008	8d	22	00	00	8d	22	00	00
0x20000010	8d	22	00	00	8d	22	00	00
0x20000018	8d	22	00	00	8d	22	00	00
0x20000020	8d	22	00	00	8d	22	00	00
0x20000028	8d	22	00	00	8d	22	00	00
0x20000030	8d	22	00	00	8d	22	00	00
0x20000038	8d	22	00	00	f1	0a	00	00

   

I followed Your advice and apart from systick no other interrupts are working
