I'm at the linux foundation collaboration summit
by ron minnich 10 Apr '09

saw great talks yesterday by marty connor (etherboot/gpxe) and Peter Anvin (syslinux). Really neat stuff. I'm going to talk to them (I hope) today about setting up a killer platform with coreboot, seabios, gpxe, and Peter's very cool syslinux that he demo'd; should make a very neat package for you all to try. And booting over http is interestig :-) ron

Fwd: 2PM EDT Friday: BRIEF Contributors Program Mtg (#olpc-meeting)
by Tiago Marques 10 Apr '09

10 Apr '09

Hi all, The OLPC guys will be discussing coreboot in a couple of hours, if someone would like to join to lend a hand, here's the e-mail: ---------- Forwarded message ---------- From: Holt <holt(a)laptop.org> Date: Fri, Apr 10, 2009 at 4:15 PM Subject: 2PM EDT Friday: BRIEF Contributors Program Mtg (#olpc-meeting) To: Support Gangsters <support-gang(a)laptop.org>, grassroots(a)lists.laptop.org, olpc-open(a)lists.laptop.org, "devel(a)lists.laptop.org" <devel(a)lists.laptop.org > Join us reviewing the latest OLPC/Sugar community projects today 2PM EDT (Boston Time) -- in 3 hrs from now: http://forum.laptop.org/chat Then type at bottom: /join #olpc-meeting AGENDA: * New Library Emerging! How you too can help start an XO Laptop library: http://wiki.laptop.org/go/Projects#XO_Laptop_Lending_Libraries * Which projects might you enjoy Mentoring?! http://wiki.laptop.org/go/Projects http://rt.laptop.org/Search/Results.html?Query=Queue=%27contributors%27 * Questions about free Hardware/Parts Returns just shipped: (DEADLINE PASSED!) http://lists.laptop.org/pipermail/devel/2009-March/023916.html * Fast Review of the latest (greatest!) HW/Project Proposals: *1. Coreboot and OLPC [North Carolina, USA] http://rt.laptop.org/Ticket/Display.html?id=37292 http://home.rr.com/mitchelltramper Also requests: http://wiki.laptop.org/go/Serial_adapters Project Objectives: Investigate Coreboot firmware looking from the angle of debuggability; particularly related to standby/resume, or other challenges.* 2. [GeneralCompute] Project Proposal - Request for platform. [Cambridge, UK] http://rt.laptop.org/Ticket/Display.html?id=37443 http://wiki.laptop.org/go/Projects/GeneralCompute Project Objectives: Most computing device in the market have more that one processor i.e. CPU, GPU (programmable/non-programmable), DSP etc. These processors are supplied by different or same vendor. But to take advantage of these processors, vendors usually supply different set of APIs for each of these processors. There is a publicly available open standard that defines a common API to take advantage of these heterogenous computing devices. The OLPC laptop already has a GPU. Hence it already is hosting atleast two computing devices. It will be beneficial to support a "General Compute" API for the developers who can then take advantage of these devices in a uniform manner. This proposal will benefit the programmers who develop middleware or applications. 3. Apache Proxy CRCsync Project and Finger-painting Interface - USA, Belgium http://rt.laptop.org/Ticket/Display.html?id=37801 http://wiki.laptop.org/go/Apache_Proxy_CRCsync http://moodle.org http://swift.com Project Objectives: FingerPaint Project 1. Integrating a chosen paint application with TinyMCE editor as a plug-in. 2. Profiling of the software stack that is used by the fingerpaint application so that the performance can be improved: RProxy Project 1. Performance testing of RProxy modules .(Stability testing, surf the internet through the proxy to collect compression rate statistics in the logs from real-live usage in stead of artificial test scenario's, etc) 2. Development and testing of required Plugins for XO School server to integrate PaintWEB and RProxy module in the latest version of XO Engine. _______________________________________________ Devel mailing list Devel(a)lists.laptop.org http://lists.laptop.org/listinfo/devel

Hello, I was trying to run a linux kernel from FILO but got some errors.The following explains best what i did. 1.Downloaded FILO and built libpayload and FILO 2. Downloaded and built Coreboot with filo.elf as the image 3.Created a hard disk image in /home/ravi/ and formatted it *$ qemu-img create -f raw disk.img 200M $ mkfs.ext2 -F disk.img* 4.As root, mounted the disk * $mkdir /mnt/rootfs $mount -o loop disk.img /mnt/rootfs* 5.And copied vmlinuz and initrd from the /boot/ folder(openSuse11.1). *$ mkdir /mnt/rootfs/boot $ cp /boot/vmlinuz /mnt/rootfs/boot/vmlinuz $ cp /boot/initrd /mnt/rootfs/boot/initrd* 6.Unmounted /dev/rootfs 7.Started qemu:*qemu -L ~ -hda disk.img -nographic* (i had to copy vgabios-cirrus.bin from /usr/share/qemu to my home directory beacuse it qemu complained that it was missing) 8.All is well, i get FILO prompt.Now according to http://www.coreboot.org/QEMU_Build_Tutorial, i try: *filo>hda:/boot/vmlinuz root=/dev/hda initrd=/boot/initrd console=ttyS0 Error 27: Unrecognized command filo>* 9.So i try: *filo>kernel /boot/vmlinuz root=/dev/hda initrd-/boot/initrd console=ttyS0 filo>boot Booting '/boot/vmlinuz root=/dev/hda initrd-/boot/initrd console=ttyS0' read_sector: device not open File not found. filo>* What am i doing wrong ?
