How to use a custom wdt interrupt routine in ncs, because I need to record my pc pointer in the wdt interrupt routine, just like in nrf5 sdk:
void WDT_IRQHandler_real(uint32_t *sp)
{
/* PC is sp[6]*/
//R0、R1、R2、R3、R12、LR、PC、XPSR
uint32_t pc_address = sp[6];
if (nrf_wdt_event_check(NRF_WDT_EVENT_TIMEOUT))
{
nrf_wdt_event_clear(NRF_WDT_EVENT_TIMEOUT);
}
ram_remain_info.wdt_pc_addr = pc_address;
//remian_info_sync();
}
void WDT_IRQHandler(void) __attribute__((naked));
/* Cortex M3/4 */
void WDT_IRQHandler()
{
asm volatile(
"TST LR, #4\n\t"
"ITE EQ\n\t"
"MRSEQ R0, MSP\n\t"
"MRSNE R0, PSP\n\t"
"LDR R1, =WDT_IRQHandler_real\n\t"
"BX R1");
}
