Extract debian etch armel distribution (um, from where?)
Add two device files to /dev
mknod ttyS0 c 4 64 mknod null c 1 3
Copy kernel modules from /lib/modules in sarge (where is that?)
We mount an NFS-Root filesystem on /root/etch_rfs
mount 192.168.0.999:/foo/bar /root/etc_rfs chroot /root/etch_rfs
Set up /sys and /proc:
mount -t sysfs /sys mount -t proc /proc
Using the serial ports: Remember they are named differently from the TS-7260
You need to insert the tsuart kernel modules:
modprobe tsuart1 modprobe tsuart7800
From then, serial ports are named /dev/ttts0 through /dev/ttts9

How to config kernels, etc...
Latest version of kernel modules are here: ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/
For permanent installation, add tsuart1 and tsuart7800 to /etc/modules
COM2 is /dev/ttyS1. You need to comment out the getty in /etc/inittab
For now, daughterboard AVR is located on pins 13&15 of DIO.
Here is a step by step guide to creating a bootable sd card
There is a serious problem with the nand kernel modules from TS, and there are three different versions out there. All of them are named either ts7800.ko or ts7800_nand.ko
- The one with md5sum 560595f538f83bf360aec50a05ca859b will cause corruption of the nand, especially due to a conflict with the uart driver. Replace posthaste.
- The one with md5sum a38658a7e99a584cd514aa0a22412127 seems to work ok. It is found in the march modules. Use it.
- The one with md5sum 884fab660d977881ecadb3de7375bb49 doesn't seem to allow us to read the nand at all with the current kernel. This is also the most recent version, so maybe it corresponds to a newer kernel version.
