Linux 2.6.17.9-ep93xx-pxa-ads1

As always, we welcome your feedback and your contributions to linux.
This version
  • Supports BitsyXb, Sphere and Portal boards.

  • Supports USB Client on the BitsyXb and Portal.

  • Adds frame buffer IOCTLs that support video acceleration.

  • Fixes a problem that caused the Portal system clock to run slow. (The real time clock was not affected.)

  • Fixes a problem that was preventing the bottom edge of the Sphere's framebuffer from being displayed.

  • Fixes CF card removal on Sphere so 'cardctl eject' is not required.

  • Has improved support for MMC and SD cards.

  • Supports PCMCIAutils (so cards can be mounted without loading cardmgr, eliminating the need for an initrd in some cases).

This version does not
  • Support operation of the Sphere as a USB client device.

  • Support audio input on the Sphere.

  • Support the Portal's USB host port on the SM501 (J10). Use the NEC USB host ports (J30 & J31) instead.

  • Reliably support all USB 2.0 devices on the Portal at high-speed (480 Mbps).

  • Support the CF socket on the Portal (but does support 16-bit and 32-bit cards in the PCCard slot).
Important Warnings and Requirements
  • Do not use a personality board older than Rev A on the BitsyXb.

  • Intel NPE Ethernet modules are required to use the Portal's on-board Ethernet ports. Contact us if you need these modules.

  • To build the kernel, use a recent toolchain known to support 2.6 kernels and your board's CPU. For cross compiling on an x86 linux system, you can use arm-linux-gcc-3.3.2.tar.bz2 [MD5] (originally from handhelds.org). This is the toolchain we used to build the precompiled kernels provided below.

    Download the toolchain fron the link above, untar it in your root directory, and add it to your path.
    cd /
    bzcat arm-linux-gcc-3.3.2.tar.bz2 | tar -x
    PATH=/usr/local/arm/3.3.2/bin:$PATH
    • The /usr/local/arm/3.3.2/ path is hardcoded in this toolchain. Do not attempt to install it anywhere else. This is the only path that will work.
Kernel source and patches
  • linux-2.6.17.9.tar.bz2 (~40MB)
    Download the kernel source from the link above or from kernel.org and make a base directory.
    bzcat < linux-2.6.17.9.tar.bz2 | tar -xf -

  • Change to the linux-2.6.17.9 directory and remain there to apply the following patches.
    cd linux-2.6.17.9/

    Apply the patches in the order listed. For each patch, download it from the link provided and apply it using patch level '-p1'.

  • linux-2.6.17-fastfpe.diff.bz2 (~14kB)
    bzcat linux-2.6.17-fastfpe.diff.bz2 | patch -p1

  • linux-2.6.17.9-ep93xx.diff.bz2 (~22kB)
    bzcat linux-2.6.17.9-ep93xx.diff.bz2 | patch -p1

  • linux-2.6.17.9-ep93xx-pxa.diff.bz2 (~83kB)
    bzcat linux-2.6.17.9-ep93xx-pxa.diff.bz2 | patch -p1

  • linux-2.6.17.9-ep93xx-pxa-ads1.diff.bz2 (~218kB)
    bzcat linux-2.6.17.9-ep93xx-pxa-ads1.diff.bz2 | patch -p1

    • Configure the kernel using your board's default configuration settings. For 2.6.x kernels, the naming convention is
    make machine_defconfig
    where machine is the name of your board. You can change individual configuration settings later with
    make menuconfig

    After executing the line below for your board
    make adsbitsyxb_defconfig
    make adssphere_defconfig
    make adsportal_defconfig
    you can build the kernel with
    make zImage

    The kernel zImage will be in the arch/arm/boot/ directory.
Root File System
    There are several root file systems that are suitable for use with this kernel.
    Visit the Root File Systems topic to learn more.
    For best results, be sure to use one of the 2006-08-29 (or newer) Debian releases.
Precompiled Kernel Image
    You can download a precompiled Linux 2.6.17.9-ep93xx-pxa-ads1 kernel image for your board configured and tested as shown.

This release has a problem with power management on the BitsyXb. If a BitsyXb is used without a personality board or with one that doesn't have a CPLD (that's most of them), the BitsyXb cannot resume from sleep. This patch corrects the problem. We expect to release a new version that includes this fix in a few days.
