<pre class="k9mail">Hi everybody,<br /><br />Since this is my first post on this list, please allow me to get off my<br />chest a few things:<br /><br />- huge thanks to Luke for getting this project started<br />- me = funding a PFY laptop, eagerly awaiting for it to arrive ;-)<br />- me = working at a research institute, focused on hardware security<br /><br />As a private individual but also as at work, having an EOMA68 card based<br />on an NXP i.MX7 would be very useful. It is a powerful processor with a<br />heterogeneous architecture (2x A7, 1x M4) which makes it an interesting<br />choice for energy-limited applications (M4 can turn off/on A7) and<br />scenarios where safety/security are important (M4 can do real-time aside<br />from workload on A7).<br /><br />The i.MX7 has many useful security features (crypto accelerators,<br />high-assurance boot, TrustZone, etc.).<br /><br />An initial check with the EOMA68 infrastructure indicates compatibility.<br /><br />My personal goals with this are as follows:<br />- Create an EOMA68 card with i.MX7 to complement my research (in fact, I<br />simply need a good demo for the stuff I'm doing)<br />- Provide the community an even better microprocessor card<br />- Have a complex PCB project to learn along the way (I did PCB designs<br />beforehand but never that complex)<br /><br />The project outline is roughly as follows:<br />- 1 Use a phyBOARD-Zeta and a set of adapters to check compatibility of<br />the i.MX7 and the EOMA68 infrastructure once the PFY laptop arrives [1]<br />- 2 Create a PCMCIA-II card featuring the i.MX7 (goal: release as board<br />+ schematics to the public)<br />- 3 Create a PCMCIA-III card protected with a high-security<br />tamper-resistant enclosure that makes physical access improbable (I will<br />not comment on this prior to publication as it is my research project),<br />check for example [2]<br /><br />What would be of interest to me is the following:<br />- How well the idea of having an i.MX7 card is received<br />- How important the use of an open source CAD program is. I have access<br />to Altium and have used it beforehand. However, KiCad has made<br />significant progress since CERN is involved. Using KiCad would make it<br />easier for the community to modify the board but since soldering these<br />components by hand is impossible anyway, would there be any benefit in<br />having freely accessible design files?<br />- General interest in a tamper-resistant enclosure<br /><br />To make the development easier, it would be nice if Luke could provide<br />us (the community) with:<br />- proper drawings for the outline of his PCB<br />- PCMCIA connector type/enclosure and height requirements of PCB<br />- mechanical verification package (as order option on crowdsupply) to<br />provide a "getting-you-started" package for EOMA68 card developers;<br />possibly including: PCMCIA receptable, connector, enclosure, etc.<br /><br />Please let me know what you think. Also, please keep in mind that this<br />is a kind of fun project for me at work and therefore the time I can<br />spend on this is limited. Progress will be slow but I will be sending<br />updates to the mailing list.<br /><br />Cheers,<br />Vincent<br /><br />[1] <a href="http://www.phytec.eu/product/single-board-computer/phyboard-zeta">http://www.phytec.eu/product/single-board-computer/phyboard-zeta</a>/<br />[2] <a href="http://www.design-shift.com/orwl">http://www.design-shift.com/orwl</a>/<br /><br /><hr /><br />arm-netbook mailing list arm-netbook@lists.phcomp.co.uk<br /><a href="http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook">http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook</a><br />Send large attachments to arm-netbook@files.phcomp.co.uk</pre></blockquote></div><br>
