RTD 5.0.0 Can LLCE

yanis-waabi — Thu, 23 Jan 2025 21:32:40 GMT

Hi,
We are trying to setup s32g3 eval board with CAN LLCE, the LLCE 1.0.9 doesn't seem to work out of the box with RTD 5.0.0.

Is there another driver available, also is it possible to use LLCE with MCAL driver and not Autosar.

Thank you in advance

Hello @yanis-waabi,

LLCE 1.0.9 (which is the latest version) was tested with RTD 4.0.2, therefore that is the officially supported version. For version RTD 5.0.0 this has not being officially tested and hence we do not have any document indicating if it is compatible or not. So I would recommend using version 4.0.2 for now. I apologize for the inconveniences.

Best regards.

I'm trying to incorporate the LLCE example into another project.
But I'm getting this error

../RTD/src/Can_43_LLCE.c:62:10: fatal error: SchM_Can_43_LLCE.h: No such file or directory

Do you know what I need to change in my configuration to fix this issue ?

Hello @yanis-waabi,

Please share the following information so I may be able to help you:

- can you confirm if you can find the file manually? in my setup it is in the following path:

C:\NXP\S32DS.3.5\S32DS\software\PlatformSDK_S32XX_4_0_0\RTD\Rte_TS_T40D11M40I2R0\include\

Please note that the path may change depending on your S32DS version and installation directory.

- Please let me know if you have successfully build CAN LLCE examples in the past.

- Please share your S32DS peripheral view, it should look something like the following:

- Please also share the exact steps you are performing to build the project.

Thanks in advance for the information.

Sorry for the misinformation I shared before.

Hi,
I'm using DS 3.6.0 with LLCE 1.0.9 and RTD 5.0.0

My peripheral view is the same as the one you provided.
The file exists under C:\NXP\S32DS.3.6.0\S32DS\software\PlatformSDK_S32XX_4_0_0\RTD\Rte_TS_T40D11M50I0R0\include
If I manually copy it initially it doesn't get included like the other files.

Another issue I encountered is that I had to modify the linker script by adding this

.llce_can_sharedmemory (NOLOAD) : { /* ------------------------------------ can_43_llce_sharedmemory sections ------------------------------------ */ . = ALIGN(0x4); *(.llce_can_sharedmemory) } > LLCE_CAN_SHAREDMEMORY

Now the project is compiling

Hello @yanis-waabi,

did you update the code (with the code generation tool) after adding the LLCE module into the peripherals? The file with me is automatically created after updating the code in the following path:

Given that after you copied the file it worked correctly, we can discard problems with your include path.

About the Linker, after checking the examples, there are some other reserved memory regions you may need:

.llce_boot_end (NOLOAD) : { /* ------------------------------------ llce_boot_end sections ------------------------------------ */ . = ALIGN(0x4); *(.llce_boot_end) } > LLCE_BOOT_END .can_43_llce_sharedmemory (NOLOAD) : { /* ------------------------------------ can_43_llce_sharedmemory sections ------------------------------------ */ . = ALIGN(0x4); *(.can_43_llce_sharedmemory) } > LLCE_CAN_SHAREDMEMORY .lin_43_llce_sharedmemory (NOLOAD) : { /* ------------------------------------ lin_43_llce_sharedmemory sections ------------------------------------ */ . = ALIGN(0x4); *(.lin_43_llce_sharedmemory) } > LLCE_LIN_SHAREDMEMORY .llce_meas_sharedmemory (NOLOAD) : { /* ------------------------------------ llce_meas_sharedmemory sections ------------------------------------ */ . = ALIGN(0x4); *(.llce_meas_sharedmemory) } > LLCE_MEAS_SHAREDMEMORY

Please check example Can_Llce_DS_Loopback_S32G274A_M7.

Let me know if this information was useful for your problem.
