We want to continue on the CAN-BENCH project started by Martin Jerabek https://gitlab.fel.cvut.cz/canbus/zynq/zynq-can-sja1000-top/-/wikis/home https://gitlab.fel.cvut.cz/canbus/zynq/zynq-can-sja1000-top/-/wikis/uploads/56b4d27d8f81ae390fc98bdce803398f/F3-BP-2016-Jerabek-Martin-Jerabek-thesis-2016.pd We want to use XCAN on Xilinx Zynq 7010 with timestamping in the first iteration, then switch to our CTU CAN FD core and add timestamping to its driver. Is there some more recent attempt to add timestamping to XCAN driver than that original work of Martin Jerabek? Is there some suggestion which driver is the right example to implement timestamping now? Our intention is to implement feature in state ready for mainlining and we hope that with your feedback we succeed this time.
