【Abstract】This paper based on the UDS diagnostic protocol and the auto factory's write specification，aset of write upper computer and domain controller Bootloader upgrade scheme based on CANFD communication is designed. Theupper computer is independentlydeveloped byTsmaster.OnlyFlash DriverandApp filescanbeimported toachieve a complete brush and write process，which is efficient andpractical.In the domaincontrolerscheme，thedesign principleofBTprogramiscompletelyproposed，inwhichAppbackupcan ensure theintegrityofECU function，and the scheme of Flash Driver downloaded toRAMenhances therobustness androbustness of theprogram.Theexperiment shows that the upper computer schemecan realize the complete process of brushing andwriting，and the domain controller Bootloader program has high stability.
