IMX27-Spartan3A interface description

This article describe the bus interface configuration to communicate between i.MX27 processor and Spartan3A FPGA.

figure 1 - i.MX27-Spartan3A bus description

All signals plugged between I.MX27 and spartan3A are described on figure 1. Some others signals are used only for fpga configuration. For more informations about the FPGA wiring, see the APF27 schematics and the i.MX27 reference manual, especially the WEIM chapter.
