Hi all,

I am working RM42X LaunchPad. I configured SCI Driver enable, VIM0-31 13th Interrupt LIN Level0, and enabled TX interrupt in the SCI Tab.

sciInit();
scilinREG->SETINT = (uint32)SCI_TX_INT;
sciEnableNotification(scilinREG, (uint32)SCI_TX_INT);
scilinREG->GCR1 |= 0x80U;
_enable_IRQ();

This is the code I included in the main program. But it is not generating the Interrupt. But when i check Txinterrupt flag is set. But it is jumping into to notification code. Kindly somebody help to resolve the issue.

HW: I think this means it goes to the interrupt service routine. Notification code is called in the ISR.

Thanks in advance.

Thanks & Regards,

Hi Haixiao Weng ,

             Thanks for your valuable reply.

             In my post, I communicated wrongly . My actual problem is,it is not jumping into the void linHighLevelInterrupt(void) code.

            Is there any setup I have to do additionally ??

Thanks in advance.

Thanks & Regards,

Hi Haixiao Weng,

           Thanks for your reply.  But There is no  "void sci1HighLevelInterrupt(void)" function is available in sci.c.

Can you post the sci.c and sys_startup.c file?

Sounds like we use different versions of HalCoGen generated file.

Hi Haixiao Weng,

Please find the attachment of sys_startup.c and sci.c.

I looked into the code. The init of the VIM should be inside the vimInit(); in sys_startup.c. Can you track it down to see which function is mapped to the SCI channel? or if it is a CCS project, once you upload the whole project, I can find it for you.

Hi Haixiao Weng ,

                   Still I am getting the same problem... It is not jumping into sci notification itself.

Thanks & Regards,

Umesh T

Please find attachment of my snapshot window of CCS while running the same program which you sent. It never jumped into Lin high interrupt service routine.. But some dummy data I am able to see in Terminal window.

Otherwise can you attach the entire project which you got the output,.

Thanks & Regards,
