Attention Pilot programs: upgrade your B2s!
Pilot programs with B2s and earlier should apply to have them upgraded to B4s or C2s (G1G1 machines) in order that you can continue to use the latest software releases. Our developer and pilot processes have been somewhat stalled for a while, but I've been told that they've been recently unjammed and we've got a backlog of developer machines to get out to y'all. Please apply at http://projectdb.olpc.at/ and state that you are upgrading B2 machines (a bit of information about the state of your pilot would probably be appreciated as well). Thanks for bearing with us! --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

B2s and OFW
Hi Mitch! Would you recommend using firmware version q2d07 on a B2-1 unit? And, btw, I assume 'save-nand' in q2c25 won't create the respective crc file, right? It did not in a test, at least. Thanks a lot! Ricardo Carrano ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: B2s and OFW
Yes, I installed q2d07 in two B2-1 units. I am experiencing problems with battery charging, (hence my question). But it seems is is just a coincidence. Those units did not have a pre-q2d07 life that I know and maybe the problem was already there. Thank you very much!

But I don't know of any reason why it wouldn't work. I just loaded Q2D07 on a B1. It seems to be working okay from the firmware side of things - I can do copy-nand network accesses and dir nand:\ and things like that. But the kernel is hanging somewhere in the early startup - no kernel messages on either the screen or the serial port. I'm not entirely surprised; IIRC that B1 was flaky the last time I tested it, which was some time ago. Oh, I see what is happening. This B1 has a bad 14 MHz clock - the OFW diags caught the problem. So my best guess is that Q2D07 is good on everything B and later. (I assume my A-Test board will have to stay with some really early firmware, especially because it needs that CL2.5 patch.)

Re: B2s
Yes, what I meant was that if we got, for update.2, sugar's cpu and mem usage where we want it, perhaps that would be enough to run on b2s. Volunteers could then do images combining a base system from 406 and the latest sugar components. I don't see how the sugar team could divert efforts into supporting b2 machines, but certainly we have some goals in common.

I was just about to start asking along these lines. There is a critical need for the wireless hardware. Fixing bug #46 is highly likely to cause the destruction of a few wireless chipsets. At least one of the people working on bug #46 is currently without any hardware. Having extra hardware increases testing bravery. Having the physical hardware is best. It's especially needed in Europe, but also in the USA. Remote access is also useful, especially if you have special equipment (can backup and restore the little eeprom chip, can watch USB traffic, can trace out the wiring, etc.) to help with. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
