See the full block diagram here. Schematic & PCB will be open source and once the files are ready we will upload them here.

We finished whole DDR3 memory interface. This spreadsheet was used to length match signals according to Design Guide. You can also see our progress in updated Project Design files here.

We are now ending optimization of signals in inner layers. Layout of board will be finished soon.

Check our iMX6 Rex Module Mux files for Dual and Quad processors or for Dual Lite processors available for download. The IO Mux Design software is located here (log in on Freescale page is required).

We created a 3D PDF document of board with final placement. You can download it from here. To enjoy the model you will need Adobe Reader installed.

We done almost all preliminary layout. Components, also the smallest ones, are placed in their position. We created new 3D model with real placement under BGAs.

Some new schematic updates. Download updated Schematic pdf here and Altium Design files here. Older schematics and project files are still available in this folder.

DDR3 preliminary layout done. We set up rules for differential pair impedances. A module use 12 layer board with this stackup.

We also uploaded complete Altium files, not finished yet. Feel free to download them here.

iMX6 Rex is moving ahead. Curious how the DDR3 preliminary layout has been done?

Watch this video. Apart from the memory layout process, it shows also component placement under CPU:

After schematic checking, we ordered all the required components. The complete Bill of Material excel sheet is available for download here. BOM Total: $116USD / 1000pcs (for CPU 1GHz, QUAD Core, DDR3 1GB)

When the order is delivered, I will compare our footprints with physical components. After this I will enjoy the layout.
