S32G274 LLCE CAN Loopback

JunSeoHan — Thu, 09 Apr 2026 07:45:04 GMT

I would like to use LLCE CAN functionality.

First, I opened the example project Can_LLCE_DS_Loopback_S32G274A_M7 and ran “Update Code” using the configuration tool (.MEX file). However, a large number of errors occurred, as shown in the attached screenshot.

I have a few questions regarding this:

In the Clock configuration, is it acceptable to power down certain parts without affecting the operation of the LLCE example code?
In the peripheral configuration (RM_1), the example code uses Software Major Version = 4 and Software Patch Version = 2, while in my environment they appear to be 5 and 0. Is it safe to modify these values?
What is Mcu Scmi Platform Support?
It is not enabled in the example code, but in my case, enabling it removes some configuration errors.
If the above changes are not critical, I can eliminate the configuration tool errors by modifying these settings. However, the LLCE CAN initialization still fails.

Specifically:

In Can_43_LLCE_Init, the driver status remains CAN_43_LLCE_UNINIT.
Inside the internal function Can_Llce_ExecuteIfCommand,
Can_SharedMemory.aCanCmd[0].eCmdId is LLCE_CAN_CMD_INIT_PLATFORM, and
Can_SharedMemory.aCanCmd[0].eReturnValue is LLCE_FW_NOTRUN.

Could you please help identify what might be causing this issue and how to resolve it?

hi,JunSeoHan

Thank you for your reply.

Refer to the Release Note, if you use the LLCE version of 1.0.11, you should use the RTD version of S32G RTD (Real Time Drivers) SW32_RTD_5.0.0 QLP03 and the S32DS IDE version of 3.5.13.
