Linux 2.4.19-rmk7-pxa2-adsx7

This version
  • Only supports AGX and BitsyX boards.

  • Enables the watchdog timer in the default configuration (and precompiled kernels).

  • Enables support for PCMCIA serial interface cards in the default configuration (and precompiled kernels). Updates the ramdisk root file system to support serial PCMCIA.

  • Updates the ramdisk root file system to provide specific examples for Earthlink dialup and for Verizon wireless in /etc/ppp.

  • Adds /proc/sys/ads-misc entries to support read access to the on-board flash serial number and to allow control of the polarity of backlight intensity and on-off signals.

  • Turns USB power off during sleep.

  • Fixes a problem that prevented the AC97 audio codec from working after waking from sleep.
Important Warnings and Requirements
  • Do not use a connector board older than Rev A on the BitsyX.

  • To build the kernel, you must use a compiler that supports the Xscale CPU.
    You can use the one we used to build the precompiled kernels provided below.
    Download arm-2.95.3.tar.gz , untar it in /usr/local/ and add it to your path.
    cd /usr/local
    tar xzf arm-2.95.3.tar.gz
    PATH=/usr/local/pxa/bin:$PATH
    • You only need this compiler to build the kernel and modules.
    You do not need to use it to build your user programs.
    You should use the LART compiler referenced in Cross Compilers for those.
Kernel source and patches
  • linux-2.4.19.tar.gz (~32MB)
    Download from ftp://ftp.kernel.org/pub/ and make a base directory.
    mkdir -p /usr/local/src/2.4.19 (you can use a different directory)
    cd /usr/local/src/2.4.19/
    tar xzf linux-2.4.19.tar.gz

  • patch-2.4.19-rmk7.gz (~740kB)
    Download from ftp://ftp.arm.linux.org.uk/pub/armlinux/kernel/v2.4/ and apply the patch.

We have a BitsyX Rev C Board, and Companion Board of Rev B. Are these board compatible? Bcoz when we power on the board, we see junk characters are dumped on to the console.

Any h/w or s/w modification/patch is necessary for the board(to serial) to work properly?

We also tried with latest kernel posted in this webpages (adsx7). Still the same Prolem persist.

Thanks for your post. This may be a port initialization issue in the boot code (take a look at the information we've just posted at topic 1321 for details). This probably has more to with the parts populated on the board than the revision of the BitsyX.

Can you let us know which port(s) you are seeing this issue on? Also, it will help to know what personality board you are using; our boards are currently at revision A. Please respond in the Open Discussion forum.

We'll take a look at this issue and let you know what we find.
