INT_SYS_InstallHandler

dearwww2000 — Tue, 03 Dec 2019 09:33:20 GMT

example "wdg_pal_interrupt_s32k118" , there are two "INT_SYS_InstallHandler":

/* Install IRQ handlers for WDOG and SysTick interrupts */

INT_SYS_InstallHandler(WDOG_IRQn, wdg_pal_Handler, (isr_t *)0);

INT_SYS_InstallHandler(SysTick_IRQn, SysTick_Handler, (isr_t *)0);

But the project no "flash_vector_table " define.

If we need to define "flash_vector_table ", where we need put it ?

Hi,

by default is vector table copied from FLASH to RAM. This allows you to add new interrupt handler in runtime by INT_SYS_InstallHandler() function.

When the vector table is only in the FLASH, you can't use INT_SYS_InstallHandler() SDK function.

If you need only FLASH vector table - just define this symbol in preprocessor settings:
