Support for hardware timestamp for socketcan firmware #4

Open splatch opened 3 years ago

splatch commented 3 years ago

SocketCAN allows to source hardware timestamp for all frames received through certain interface.

Currently using candump .. -H results in printing times of 1970 which means that this information is missing from controller. Relevant code section in canutils: https://github.com/linux-can/can-utils/blob/v2021.08.0/candump.c#L615L635

@Lukasz-Juranek Looking at gs_usb kernel driver itself I think this feature is already there. I see one of timestamp related constants referenced after switch to candle light. Did 0002 release include hardware timestamps?

Yes at embeedded site it seems implemented but at GS_USB it is defined in gs_usb_breq but value GS_USB_BREQ_TIMESTAMP is never send, so for me not works with GS_USB
