more revisions to the interface, these are last-minute just before finalising: * the revision 2.2 A20 cpu card * the revision 0.1 ICubeCorp IC1T cpu card * the revision 0.1 Ingenic JZ4775 cpu card * the revision 0.1 Micro-Desktop base board * the revision 3.0 Tablet / Mini-Laptop base board * also i have received the documents for the quad-core Allwinner A33 so will be starting a CPU card for that with 2GB RAM, shortly. i will have enough money coming in beginning of this month to send the revision 2.2 A20 CPU Card off to the factory for 5 samples. the revision 0.1 Micro-Desktop will follow very shortly after that. the IC1T icubecorp found me an SD-based TSOP-48 from a company called FORESEE, which comes in a low-cost 2GB variant. i will add that in (replacing the BGA variant which is 4Gb minimum, requires very small tracks, is more expensive and is making me nervous). the jz4775 cpu card i had to do a minor shuffle of the I/O lines as there was some I/O multiplexing sharing SPI with MMC so there is a bit more work there. heck of a lot going on, it is ironic that about four really good CPU cards should all come out pretty much at the same time... l.

tablet/laptop pcb rev3
by Luke Kenneth Casson Leighton 24 Jul '14

24 Jul '14

ok opportunity with the cpu card interface redesign to do a layout change, i'm taking out the atsam4s and replacing it with a VC0345 camera IC, PCA9536 I2C-to-GPIO converter, and am putting in a Micro-SD on the top edge of the PCB (so that things like the IC1T card can use it). ethernet and the extra USB i will route to an FPC which can go to a daughterboard for when this is used in a mini laptop. USB audio remains as-is using the CM108AH. basically the tablet pcb becomes a usb / i2c peripheral board, something i didn't want to do because i wanted the educational and experimentation sector covered as well. l.

list upgraded
by Alain Williams 10 Jul '14

10 Jul '14

If there is anyone with a dmark setting address (eg yahoo.com) their emails will be treated slightly differently but it should work. They may find that they have an administrative block put on them -- I did that to prevent problems earlier. Please ask and it will be removed. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.

This list may be up & down for a bit
by Alain Williams 10 Jul '14

10 Jul '14

I am going to update the software to mailman 2.1.18-1 My motivation is to deal with the problems that were causes by yahoo a few months ago when it changed its dmarc settings. This was why yahoo users were forbidden from posting to the list. This should fix this; the new version has been out for a couple of months and should (hopefully) not cause problems. Those interested in the nitty gritty look at: http://list.org/mailman-admin.txt and search for 'dmarc'. This will happen over the next day or two.

[status] jz4775 and ic1t boards
by Luke Kenneth Casson Leighton 09 Jul '14

09 Jul '14

ok both the jz4775 and ic1t cpu cards pass routing and plane (connectivity) checks, it's what i've been spending my evenings on, over the past couple of weeks. i have to consider replacing the SD/MMC card slot on the IC1T board with a BGA 11mm eMMC because SD/MMC is not as reliable, eMMC has 8 data lines and will be faster. BGA 159 pin eMMC will just about fit and will simplify the design slightly. more later, will create PCB images etc. l.

HummingBoard becomes partially what eoma would've been
by Lauri Kasanen 07 Jul '14

07 Jul '14

Hi, They announced the HummingBoard recently. Its specialty is that the outer interface is rpi-compatible, but the cpu and ram can be replaced. So while the interface is not open I believe, that's getting closer to what eoma would have been. Thought to let you know. - Lauri
