Hello Marc and others, Matyas Bobek has implemented FlexCAN emulation for i.MX6 targets in the frame of his bachelor thesis
https://dspace.cvut.cz/bitstream/handle/10467/122654/F3-BP-2025-Bobek-Matyas-BP_Bobek_FlexCAN_final_4.pdf with reviews there https://dspace.cvut.cz/handle/10467/122779 Please, if you have problems to access documents, try that later, our large archive with theses and publications is under "AI" scrape-bots attacks almost permanently... or send me note and I send the document directly. The project continues and on base of Marc Kleine-Budde review, Matyas Bobek has implemented timestamping which should ensure correct messages ordering even if FIFO mode is not used in the drivers, Linux driver default case. There is even workaround to advance timestamp if the the QEMU virtual time is too coarse to provide unique values for for too fast delivered messages through virtual bus without real bits serialization. The actual code is available on the "flexcan" branch of the repository https://gitlab.fel.cvut.cz/bobekmat/qemu-flexcan The clean, minimal patches sequence will be prepared for review for the proposal for inclusion into QEMU mainline, hopefully soon. In longer term perspective, I have interrest in i.MX8 and other FlexCAN variants with FD support, etc. I do not know if Mr. Bobek will have time and interest to continue in this direction. I can offer that as the another thesis or can offer that as summer job etc. But latter would need some funding for students motivation and their time compensation and I have had never and do not have any QEMU related project for such funding now and even minimal chance is even in future for other than CTU CAN FD IP core where we support silicon and FPGA products. So no timing, chances, estimates for something beyond i.MX6 FlexCAN.
