Generating LL library for FDCAN

Hi Team,

I am working on SIL2/3 compliance project. For this I need to generate and work on LL based libraries instead of HAL libraries.

I am using STM32Cube v1.19.0. and working on STM32H753xx and STM32G4A1VET6 series MCU.

I am unable to generate LL libraries for FDCAN.

Need your help support for generating LL based FDCAN libraries.

 

Regards,

Abey

Not sure what you mean by, "generate LL libraries" ?

The LL code is provided by ST in the firmware pack - you don't "generate" it.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Thank you @TDK 

For SIL2/3 compliance, "HAL" library-based coding Standard is acceptable?

If not, what are the other coding standard options for SIL2/3 compliance-based project?

Abey

Yes,,our team connected with ST supplier for signing NDA to get the functional safety libraries. This process is in progress.

Meanwhile, we are  working on the FDCAN config and communication establishment for STM32H7 and STM32G4 series.

But we need ST support team to confirm if, "HAL" library-based coding Standard is acceptable for SIL2/3 compliance or not?

If not, what are the other coding standard options for SIL2/3 compliance-based project?

This is important for us to align on coding standard.

Your original question is answered. Nothing about SIL in the OP.

If you have a new question, perhaps raise a new issue.

This is a community forum and isn't a direct line to ST support. If you want to submit a ticket, consider doing so here:

SIL compliance is more than just a check-the-box exercise based on which library you use.
