Which driver handles the ERR from CAN transceiver (signal name: LLCE_ERR1_B) on S32G-VNP-RDB2?

[ZeusChen]

Hi NXP Community,

According to the S32G-VNP-RDB2 schematic: SPF-47440_D3.pdf, there is a signal named LLCE_ERR1_B connect to PF_00 (GPIO[80]). The signal is wired AND form 6 CAN transceiver EER pin. It should be a interrupt signal for S32G to indicate some thing wrong about CAN bus. But the pin PF_00 is configured as the Flex Timer Channel 5 I/O in s32gxxxa-rdb.dtsi. Which driver or service will handle the LLCE_ERR1_B ? And where is the interrupt pin setting in device tree?

Hi,

Looking into the documentation for GoldVIP, all CAN features are loaded into the M7, not under the A53.

We understand you are seeing into the BSP (non-GoldVIP) DTB, which is as you are stating, being configured as FTM1.

Please, let us know.

Hi Daniel,

Thanks for your reply. I still confuse with it.
If I build the image according to BSP (S32G2_LinuxBSP_32.0_User_Manual-1.pdf), the PF_00 pin will be configured as FTM1.
So the LLCE_ERR1_B signal would has no effect?
Is there any document about the difference between GoldVIP & non-GoldVIP?

Hi,

Thanks for your feedback.

As out-of-the-box, PF_00 will be configured as you say under the NXP BSP (or non-GoldVIP). As to the effect, since PF_00 will be an output, we might say that you are correct.

As for a document stating the differences between GoldVIP and non-GoldVIP, there is not. The general idea of GoldVIP is providing a proof-of-concept of the capabilities of the platform. The non-GoldVIP is a blank canvas, that you can use to start development.

Please, let us know.
