The bootloader supports only the necessary services. 16 KiB of flash memory are sufficient for the emotas bootloader \u2013 and it is still j1939 compatible.<\/p>\n<p>The J1939 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>Highlights<\/h2>\n<ul>\n<li>J1939 compatible<\/li>\n<li>segmented transfer and block transfer using CAM11\/CAM21<\/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 J1939 devices need bootloaders to update firmware in the field.
