S32R Interrupt cannot enter

binqin — Tue, 12 Jul 2022 10:43:57 GMT

Hello，

The compiler used in this project is WindRiver, interrupt cannot be entered. Can you help to solve it?

In addition, I found the root cause of this problem is startup.s, interrupt vector is not registered. I took simulation, and the state of the register is correct, as shown as in the figure.

Hello,

Since the MCAL driver doesn't register the interrupts, you have to register the interrupts manually.

Best Regards,

Nam

Hello,

You should find the vector table, which registers the interrupt, in the startup code, e.g. Vector_Vle_App_Interrupt.s, then modify the corresponding interrupt handler ID. The vector table address then should be written to IVPR register. See the attachment.
