Creating a bootable SD card

Setting up SD Card Partitions for Bootloader and Linux RootFS

You can use the following script in order to format an SD-card from that an AM335x can boot:

if [ ! "$1" = "/dev/sda" ] ; then
    unset LANG
        umount $DRIVE"1"
        umount $DRIVE"2"
    if [ -b "$DRIVE" ] ; then
        dd if=/dev/zero of=$DRIVE bs=1024 count=1024
        SIZE=`fdisk -l $DRIVE | grep Disk | awk '{print $5}'`
        echo DISK SIZE - $SIZE bytes
        CYLINDERS=`echo $SIZE/255/63/512 | bc`
        echo ,9,0x0C,*
        echo ,,,-
        } | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE
        mkfs.vfat -F 32 -n "boot" ${DRIVE}1
        mke2fs -j -L "rootfs" ${DRIVE}2


The following script copies all files onto the SD-card:

if [ ! "$1" = "/dev/sda" ] ; then

  sudo mount $DRIVE"1" /mnt
  sudo cp $SRC/MLO /mnt
  sudo cp $SRC/barebox.img /mnt
  sudo cp $SRC/uImage-pcm051 /mnt
  sudo umount $DRIVE"1"

  sudo mount $DRIVE"2" /mnt
  sudo tar zxf $SRC/root.tgz -C /mnt
  sudo umount $DRIVE"2"

Accessing GPIO inputs as interrupt from userspace

The Linux kernel offers an UIO-driver for this purpose. For usage see Linux-kernel-documentation within "DocBook/uio-howto.tmpl" or online this link:

Decreasing amount of available RAM

In order to change the amount of available RAM for example to 512 MB, you need to add "mem=512M" parameter within Barebox's environment.

For current BSP versions this means to add "mem=512M" within "/env/config-board" at the end of the line:

global.linux.bootargs.base="console=ttymxc3,115200 enable_wait_mode=off vt.global_cursor_default=0 consoleblank=0 mem=512M"

Out of 512MB RAM, 128MB will be allocated to GPU and 384MB for general uses. Depending upon your requirement you can change GPU memory size. In order to modify the GPU memory size you need to make modification in kernel
board config file.

Verwendung eines Nameserver anmelden

Damit auch bei fix eingestellten IP-Adressen ein Nameserver verwendet wird, sind die folgenden Einstellungen vorzunehmen:

In die /etc/resolv.conf gehört ein Eintrag der Art:

In der /etc/nsswitch.conf muß der Eintrag "hosts: files" erweitert werden zu "hosts:files dns".

Ein gültiger Default-Gateway sollte eingestellt sein, erkennbar daran, daß die Anweisung "route" eine Zeile "default" mit ausgibt.

Wo finde ich die Linux-Sourcen und sind diese schon an die PHYTEC-Module angepaßt?

Auf unserem FTP-Server finden Sie unter eine Auswahl unserer Module. Das darunter befindliche Verzeichnis "Linux/" beinhaltet die letzte(n) aktuelle(n) BSP-Version(en). Diese bestehen aus den fertig flashbaren Binary-Images sowie einem OSELAS-Tarball und der PTXdist-Toolchain.

Der OSELAS-Tarball enthält außer den letzten PHYTEC-Patches selber kaum Sourcen. Vielmehr ist es ein Regelwerk, mit dem PTXdist die Binary-Images erstellen kann. Dazu ist eine Verbindung zum Internet erforderlich, denn fast sämtliche Sourcen werden von dem Regelwerk aufgrund fest hinterlegter Links von dort geladen. Die Sourcen befinden sich also erst nach der Erstellung der Binaries auf Ihrer Festplatte und enthalten dann in der Tat auch sämtliche Anpassungen an Ihr PHYTEC-Modul.

Choosing the right Linux-BSP version

The essential question for deciding which Linux BSP version is the right one for your Wega board are the version numbers of the printed circuit boards of Wega and AV adapter. You'll find them when you dismount the AV adapter from the Wega.

Wega and TTL-RGB adapter (PEB-AV-02)
1405.1 or 1405.2 (Wega) + 1415.1 (PEB-AV-02): BSP PD14.1.0
1405.0 (Wega) + 1415.0 (PEB-AV-02): BSP PD13.1.0_CR1

Wega and HDMI adapter (PEB-AV-01)
1405.0 or 1405.1 or 1405.2 (Wega) + 1406.0 or 1406.1 (PEB-AV-01): BSP PD13.0.0

For instructions of how to flash BSPs see Wega's Application Guide (download link L-792e.pdf aside), chapter 4.4 "Updating the software".

Status of HDMI driver

Status of HDMI driver

The BSP Linux PD13.0.0 (alpha) Release supports HDMI in experimental state, which means it's not production quality.
The limitations concern coding quality as well as test depth.
Supported Resolutions are only 720p and XGA.
No EDID recognition of monitors.

The first BSP release of production quality (PD13.1.0) will have HDMI deactivitaed due to these restrictions.
Implementation of good HDMI driver will take some more time, but will also be done.

Setting boot mode DIP-switch

For booting from SD using PCM-953 baseboard card DIP-Switch S5 must be set to ON-ON-ON-ON-OFF-ON-OFF-OFF.

Booting from USB

Datasheet of the prozessor shows in chapter "USB Boot Procedure", that the processor's boot sequence uses USB in order to establish an IP-connection to a tftp-server. So it's not intended for booting from an USB-Stick.

Furthermore Barebox is not able to boot from USB. Some related coding it contains will not run.
