A lot of people got hold of a Toradex T20 board which was given away in exchange to a €20 donation to the red cross (if I remember correctly).
To get Archlinux running quickly on the T20 running the rootfs from a micro-sd card (kernel stays on internal NAND flash, so does the toradex firmware):
- Get the ARMv7 Tegra2 TrimSlice root filesystem and put it on a micro-sd card (first partition, create a ext4 filesystem for it).
- Getl the T20_LinuxImageV2.0Alpha2_20121019.tar.bz2 from Toradex, put the T20 module into recovery mode and install the linux-image as prescribed on Toradex' website.
- Boot the T20 board, interrupt the boot sequence. Add the following two environment variables to the u-boot bootloader:
- Run your image.
- If you are satisfied with the result, save this modification with...
setenv bootcmd run myboot
