Hi, Following FreeNode IRC channel recommendations, I would like to introduce the product we are developing in our Brazilian/USA startup company, based on Allwinner SoC: the MOD Duo.
The MOD Duo is a pedalboard with an embedded computer dedicated to live and real-time sound processing, focused in the sound conversion quality and in running LV2 (an open standard) plug-ins. Sorry for the announcement, but as this product is a sound processor, I think it is different from the regular tablets and mini-computers that usually have Allwinner SoCs. We are crowd funding this product via Kickstarter. We just launched our campaign and got 35% of its funding in the first day. The sunxi linux community is helping in every aspect of the kernel development, giving support and helping us even with hardware issues. We are actually using the 3.4.61 kernel with RT patch ( http://cb2.autostatic.com/linux-sunxi-rt/patch-3.4.61-sunxi-rt77.diff.gz). We are doing small contributions for the community, like editing some wiki pages and sharing some hardware documentation that we are hardly getting from the manufacturers. We hope that in the end of the project we will use the main line kernel and have the following features working: - USB Gadget Ethernet + Audio 2.0 - I2S - RT MOD Duo has a three board topology. - A coreboard with Allwinner SoC, currently the A20. - A base board with power, soundboard and connectors for a coreboard. - A top board with hmi (displays, buttons and encoders) with an Cortex-M3 (NXP LPC176x), implementing a pedalboard interface. We have a working prototype with Cubieboard2 and a base board that proved the concept. Now we are working on the first release candidate product that uses ITEAD A20 for coreboard. As we are having problems with the 1mm pitched connector of ITEAD, we are migrating to the Marsboard A20 (1.27mm pitched connector). You can see an image of the release candidate hardware here: http://portalmod.com/blog/wp-content/uploads/2014/08/placas-RC1-6.jpg We have a goal to do our own core board (it will be called Bubaboard after our company dog name!). It will have an A23 or A33, 512MB DDR3 and 8GB NAND. The development of this board depends on reaching the financial goal on the crowd funding. It will be totally open hardware, with schematics, gerber, and KiCad project files. I already did the initial schematic in KiCad. We will also release a simple base board with the audio codec. If we develop the core and base board, we will surely send some to the developers. We developed a soundboard from scratch following HI-FI and audiophile concepts. We are using an external codec and there are no smd components. We also developed a powerful web-based graphical interface and a host for the effects. All the software is open source and we are active contributors of Linux Audio community. I (rafaelMOD on freenode) am responsible for the hardware design and for some drivers and Ricardo Crudo (ricardocrudo on freenode) is responsible for the kernel, some drivers and firmware.
