so i*think* we can go to 2gbyte of RAM.
Good news! It could be a reasonably capable machine.
yeah. now we have to test it, at least creating a batch of minimum 5 CPU Cards. just to be on the safe side, probably make 3 with 2Gbyte RAM and 2 with 1 Gbyte RAM. i'm guessing we will need somewhere around $1.5k for 5 boards including components.
joe if i get you the modified pcb layout can you handle getting this sorted (PCB printed, populated etc.)?
No problem, but remember, as company we still need the SATA.
aw f**** :)
It would be good if you can put in some wings that can be broken off that has SATA and a lot more IO coming out of FPC. The wings should be at the HDMI end
there isn't enough space to do that....
ohhh waaait, i got one. there is *just* enough room to put an FPC20 underneath the MicroSD. 4 pins SATA.
i should just about be able to route the TS/CS group 0 (pin group PE0-PE11) through to it via a couple of routes.
that's 16 pins... actually if i make it TS/CS group 1 (pin group PG0-PG11) that would also give multiplex access to SD1 as well.
2 GND... 18... 1 5V 1 3.3V that's 20.
.... that good enough?
One 20 pin FPC at the microSD end of the EOMA with SATA and more IO pins ought to enough for anyone (TM).
Alternatively a SATA, a second USB in exchange for reduced IO pins ought to be enough for anyone else (TM).
The GND, 5V, 3.3V essential.
