S32G LLCE CAN HOH filter priority

[chansookang]

Hello,

I've been working with the S32G CAN LLCE, and it seems that the priority of HRH filters in the CanHardwareObject configuration is not mainly determined by the index or object ID order.

In my case, I had both FULL and BASIC filter types configured, and even though the BASIC filter had a lower index, it looked like the FULL filter matched first.

When multiple HOHs are configured for the same controller, how exactly is the matching priority determined? (index, basic/full, filter code size? etc)

hi，chansookang

Thank you for your information.

Refer to the RTD_CAN_LLCE_UM.pdf，All filter entries for a channel are searched in ‘order’ – the first match completes the search. Therefore, If FULL filter is tried first and it fails, search will continue and eventually match a BASIC filter.
