The bootloader supports only the necessary services. 16 KiB of flash memory are sufficient for the emotas bootloader \u2013 and it is still UDS compatible.<\/p>\n<p>The UDSonCAN Bootloader is available for different 16- and 32-bit micro controllers and can easily be adapted to other targets.  It is delivered as ANSI-C source code and thus can be extended by customers e.g. with a password protection mechanism, firmware encryption or a manufacturer-specific back door.<\/p>\n<h2>UDS services and limitations<\/h2>\n<ul>\n<li>10h DiagnosticSessionControl<\/li>\n<li>11h ECUReset<\/li>\n<li>22h ReadDataByIdentifier<\/li>\n<li>27h SecurityAccess<\/li>\n<li>31h RoutineControl<\/li>\n<li>34h RequestDownload (support of fixed\/compiled memory address in target only)<\/li>\n<li>36h TransferData (download only) <\/li>\n<li>37h RequestTransferExit<\/li>\n<\/ul>\n<p>If additional UDS services or specific &quot;update sequences&quot; are required, we offer an extension or customization of the bootloader according to your requirements.<\/p>\n<h2>Highlights<\/h2>\n<ul>\n<li>UDS compatible<\/li>\n<li>data transfer via ISO\/TP<\/li>\n<li>only little flash resources needed<\/li>\n<\/ul>\n<h3>System requirements<\/h3>\n<ul>\n<li>ANSI-C compiler<\/li>\n<\/ul>\n<h3>Scope of delivery\/Licensing<\/h3>\n<ul>\n<li>Bootloader source code (ANSI-C compatible)<\/li>\n<li>driver for CAN controller, CPU and flash access <\/li>\n<li>ready to run example application<\/li>\n<li>user manual and reference manual in electronic format<\/li>\n<li>incl. 6 (project license) .. 24 (site license) months support by e-mail or phone (depending on <a href=\"\/en\/info\/sourcecode-licenses\">license<\/a>)<\/li>\n<\/ul>\n<h6>For further questions, pricing and ordering information please contact us at +49-3461-794160 or service@emotas.de.<\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Overview An increasing number of ECUs need bootloaders to update firmware in the field via CAN.
