LIN Stack Problem with Processor Expert Mode

[chaitanya_kalyani]

I am facing issue while using LIN stack with processor expert mode.

If directly added LIN stack then getting issue ISR redefined.

If I allow macro redefinition

 

then not able to flash the program. getting error 

After commenting lin_isr.c file able to flash properly. But need a lin signals based on interrupt base.

Can you update the lin_isr.c.  Find sample code that I am trying to use in the attachment below.

Quick response highly appreciated.

Hello, 

Why do you need a Processor Expert? Wouldn't it be easier to set it up by yourself?

LIN uses interrupts that are not generated by the Processor Expert. So, when you don't use lin_isr.c it is working.

As you can see a similar case in this link "Fail to resume target process.Downloading binary to target..."  

If you look at your .map file you can see below interrupts. 

The interrupts can be generated by the init_SCI and init_TIM bean in the Processor Expert.

Best Regards,

Hello,

I am new with LIN as well as S12ZVL and working on an urgent project. 

I made some changes in lin_isr.c file and normal LIN communication working fine. 

Just not able to set CPMUSYNR register value to 0x8F through PE so setting it manually in main.

Please let me know if I am following any wrong approach and that will cause any problem or not.

Find the sample code and procedure screenshot in the attachment below.

Hello,

I'm very sorry for the delay.

It is not possible to set CPMUSYNR to 0x8F because the value of VCOFRQ = 0b10 is reserved.

Please, refer to the below table from the RM rev 2.48

Best regards,

Diana

Hello,

Thank you for your help.

I found the exact issue. The issue was with the baud rate. I added auto baud rate support from NPF and interrupt vector so it is working fine. 

But when you update LIN cfg files then need to add #include"IO_Map.h" in lin_hw_cfg.h file.
