The CI20 bare-metal stuff is rather educational and it helps to explain various things that you can see in other code related to the Ingenic SoCs. It'll be interesting to see whether the jz4775 is close enough to the other SoCs for various initialisation things to work straight away with limited reconfiguration, perhaps even things like the framebuffer.

So, was it Digikey that mixed up the parts or the factory that put the wrong IC on the board? As for the RAM, I guess that it made for the "bring up" process, as described in that bare-metal Ingenic work, to be slightly more exciting than it should have been. When you're probably only somewhat confident that the code will do the trick, I guess it's frustrating to have defective hardware involved as well. Anyway, good luck with the printing and soldering!

Heh, A whole week early in person, but didn't manage to book a proper talk slot in advance (or did you just not quite make the cut?) Very 'LKCL' :-) See you next week; I look forward to a play. Are you going to be set up on a stand/corner somewhere so we have a fighting chance of finding you in the madness that is FOSDEM?

Very > 'LKCL' :-) :) i didn't apply in advance because i didn't know how far along i'd be with the laptop. i didn't want to just bring a 3D design on-screen plus some PCBs: first assembly i literally only managed to complete 6 days ago, so that was when i contacted alasdair. i'm on standby if there's a free slot, but it will be short-notice: i'll post on-list and the arm-netbooks freenode irc > See you next week; I look forward to a play. Are you going to be set > up on a stand/corner somewhere so we have a fighting chance of finding > you in the madness that is FOSDEM? well the advantage of being here early is that i'm planning - if i understand things well enough to know if this is even possible (first time ever to fosdem) - to set up early on the "open hardware laptops" stand, plus, also, i want to speak to the people on the "3d printers" stand to ask them if they'd like to print out some of the laptop parts, on the basis that it'd be cool for both anyone demo'ing 3d printers and also for the libre laptop project. so i'll be at one or other of those stands. i'm using the time here at http://2go4.be to refine some of the parts, as this is the first time that PCBs have been inside the casework, there is some quite obvious strain in places i could not have forseen without actually having actual PCBs with fully-populated components. that, and ABS does have quite different characteristics from PLA. other than that, i'll post here (and on IRC) if there's any changes. if anyone has any suggestions (for venues / meeting-times) do say so. l.
