Booting an MSC711x Device from an MPC8272 Host Using the HDI16 Interface

PublishTime：2021-10-08

●In DSP applications such as wireless infrastructure and packet telephony, the host processor writes the data and source programs to slave devices during boot loading. Therefore, the option to transmit source programs through the host interface is an important feature of the Freescale MSC711x DSPs. The boot loader program stored in the ROM provides the code necessary to perform this procedure after power-on reset. This application note describes a general programming model for boot loading an MSC711x device through the HDI16 host interface. For purposes of illustration, it focuses on the MSC7115 DSP.
●The boot loader program stored in MSC7115 ROM loads and executes the source programs that are distributed by the host processor connected to the HDI16 port. While the boot loading procedure can be performed using any compatible host processor, a host MPC8272 processor is used in the application discussed here.
●This document assumes a working knowledge of the MSC7115 and MPC8272 architectures, along with the ability to program the MPC8272. For information on the MSC7115 HDI16 pins, registers, and programming model, refer to the MSC711x Reference Manual. For details on the MSC711xADS, refer to the MSC711xADS Reference Manual. For information on the MPC8272 processor architecture, registers, memory controller, and programming model, refer to the MPC8272 Reference Manual. All of these manuals are available at the Freescale Semiconductor web site listed on the back cover of this application note.
