PC Engines WRAP

ALIX system boards were manufacturered and sold by PC Engines. They utilise the x86-based AMD Geode SC1100 CPU (fast 486 core). The building and installation procedure is very similar to newer Alix boards except some small differences. See referred pages for more info.

There are no pre-built images for the WRAP boards available at http://downloads.openwrt.org/. The generic x86 ones will not include the appropriate drivers (e.g. wireless, LED support). Building your own image and specifying the build profile below will ensure the appropriate drivers are all included in the image.

Follow:

• OpenWrt Buildroot – About
• OpenWrt Buildroot – Installation
• OpenWrt Buildroot – Usage

Build profile should be:

• Target System: x86
• Target Profile: PCEngines Wrap

Under the most recent Backfire repository, under x86_generic, find the image named “openwrt-x86-generic-combined-ext2.img.gz”. After flashing the OpenWrt image, follow these guides to install missing packages:

• opkg update
  opkg install kmod-leds-wrap

• basic
• usb-installing
• usb-drives
• LuCI

Instead of ext2 image mentioned above, you can use squasfs or jffs2 filesystems, too. Trunk images are also available.

I just installed OpenWrt on a WRAP 2c using 12.09/attitude_adjustment. I started with Attitude Adjustment repository and placed openwrt-x86-generic-combined-ext4.img.gz on a CF. It boots with DMA enabled, which doesn't work, so you have to have several minutes of patience and perhaps hit ctrl-C several times when it stops just after

[    2.014014] sd 0:0:0:0: [sda] 1989792 512-byte logical blocks: (1.01 GB/971 MiB)
[    2.040450] sd 0:0:0:0: [sda] Write Protect is off
[    2.055800] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA

once booted and logged in via the serial port (or perhaps the network) you need to disable DMA and fix the clock source. For that mount the boot filesystem and edit the kernel boot flags:

mount /dev/sda1 /mnt
vi /mnt/boot/grub/menu.lst

add libata.dma=0 clocksource=scx200_hrt at the end of the kernel lines.

I just installed OpenWrt on a WRAP 1e-2 using 15.05/Chaos Calmer. I started with Chaos Calmer x86 generic and placed openwrt-15.05.1-x86-generic-combined-squashfs.img on a CF. It works but you need to fix the clock source. For that mount the boot filesystem and edit the kernel boot flags:

mount /dev/sda1 /mnt
vi /mnt/boot/grub/grub.cfg

add clocksource=scx200_hrt at the end of the linux lines.

See the Alix guide.
