Hello,

Unfortunately we have limited resources to support development of own flexray drivers. our recommendation is to use existing drivers. Either Autosar/MCAL drivers or third party drivers like vector.com

Best regards,

Hi,

you can find it on our web:

Autosar (Classic) Version 4.0.x | NXP 

You can select between ISO and QM version according to your needs.

It is free of charge.

Peter

petervlna,

You mentioned these Autosr/MCAL drivers are Free.

So download one of package (AUTOSAR 4.0 MCAL (QM) for MPC574xP(REV 2.0.x).

But why do we require a key while extracting this package.

Should I directly integrate required drivers into my project ??

Hello,

I have no knowledge on your project, but be aware that MCAL can be compilled by GHS or windriver.

No S32DS is supported.

Peter
