Problems using UART in interrupt mode with SK3111

JorgeSans — Tue, 11 Jun 2024 22:07:13 GMT

Hello,

I am having trouble using the UART peripheral with interrupts. The code I am publishing below does not work; nothing is transmitted, and the execution ends up in the error situation: undefined_handler. Could someone indicate what I might be doing incorrectly?

I have just forgotten to mention that any suggestions on how to use Reception with interrupts are more than welcome.

Hi@JorgeSans

Please take a look at the demo in the attachments.

This demo made base on S32K12 and I think there is no much difference between S32K311 and S32K312.

Hi @Senlent :

It is not possible to import IntCtrl_Ip_ConfigIrqRouting because I do not know how to enable the following condition. I believe it might require activating a checkbox somewhere in the configuration tool, but I have not been able to locate it.

#if (INT_CTRL_IP_MSCM_SYSTEM_INTERRUPT_ROUTER == STD_ON)

Therefore, when I try to compile my ported application to the S32K311, the following error arises:

D:\GIT\abbi\Debug/../src/main.c:81: undefined reference to `IntCtrl_Ip_ConfigIrqRouting'

The example you sent cannot be opened with my IDE as shown in the image.

Any suggestion about how to solve the issue ?

Not sure if this is relevant but I can not access this tab

Hi@JorgeSans

This is obviously an RTD version compatibility issue.

The demo I provided to you is based on RTD 2.0.2 and you can refer to it, I don't think there is a big

difference
