Partnership: EOMA68 Laptop

J JC Public Seen by 267

There is an ongoing effort to build RISC-V into EOMA68-certified computer cards. This seems like the easiest point of entry for a successful product launch.

thanks for the introduction, JC. EOMA68 is a Certification Mark, held for safety reasons as the "freedom' to kill someone through causing a short-circuit in somebody's battery-operated device is not something that anyone wants.

it is an open project so (almost) the full source code is available: i am withholding the EOMA68-A20 Card's files until the production run is complete so that we do not get knock-offs disrupting the Certification Mark and making the backers irate. everything else can be found via the links here: http://rhombus-tech.net/crowdsupply/

the thing you have to watch with EOMA68 is that a credit-card-sized form-factor is really quite small: 43mm x 78mm at the most, with a height clearance on TOP of 1.9mm and 1.6mm on BOTTOM if you use a 1.2mm PCB thickness. you can just about fit a 21x21mm SoC, 4x DDR3x8 RAM ICs, eMMC NAND storage and a PMIC circuit taking up about 5 cm2.

point is: you're pretty much guaranteed not to fit the freedom u510 into that space and still comply with the EOMA68 Standard because the freedom u510 does not have any kind of video output: you'd need to fit an entire PCIe-based 2D or 3D GPU on there and the only 2D GPU i heard of was the Volari X11. you might be able to create something in an FPGA to convert PCIe to RGB/TTL however i would not like to be the one doing the analysis.

bottom line is: now you know why i started the Libre-RISC-V project http://libre-riscv.org/shakti/m_class/
