The RTD driver maintains this setting, so configuring the module to use an arbitration scheme that prioritizes high-priority messages, thereby addressing potential priority inversion issues.</P> <P>BR, Petr</P> </DIV> Mon, 14 Apr 2025 14:06:07 GMT https://community.nxp.com/t5/S32K/S32K3-CAN-priority-inversion/m-p/2080032#M47746 PetrS 2025-04-14T14:06:07Z
