Flash/EE memory programming via LINProtocol 6

Posted: 21 Apr 2010 ?? ?Print Version ?Bookmark and Share

Keywords:flash memory programming? LIN programming? ADuC7032-8L protocol?

A key feature of the ADuC703x family of devices is the ability of the devices to download code to on-chip flash/EE memory while in-circuit. This in-circuit code download is performed via the LIN communications bus. This application note describes the download protocol implemented on the ADuC7032-8L and ADuC7033 (Protocol 6) to enable users to develop their own LIN programming tools either for series production programming or for application update.

In this application note, the host refers to the host machine (microcontroller, DSP or other machine) attempting to download data to the ADuC703x. Loader refers specifically to serial download firmware resident on the ADuC703x.

Note that this application note describes Protocol 6 only. Protocol 6 follows the general procedure defined by UDS (ISO/DIS 14229-1.2, Road Vehicles Unified Diagnostic Services). However, due to the limited code space available, the services are limited to the minimum actually required.
