Is it isl3893 based? I doubt so.

I posted on this device on the GPL violation list a while ago.

That sounds like a lot of work and reverse ingeniering. It also sounds
way over my skills, what can I read so I can ve of help? I have a lot
of experiencie with microprocesors.

We have to get the JTAG working, and then try to install another
bootloader such as u-boot.

The latest version of u-boot makes me think that the ARM946 core is supported:

ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2

***@warsaw /home/zoobab/u-boot-1.3.1 [13]$ grep 946 -r *
board/integratorap/split_by_variant.sh: echo " 1 /* CPU core is
ARM946E-S */ " >> tmp.fil

I will try to spend some time tomorrow to get the JTAG working on the
Siemens box I have.

thanks

I'm planing on purchasing, just want to know if I can get a nice
gnu/linux on it.
Its cheap and it has an usb port
thanks, for your time

I don't think it runs linux natively.
But since the device has 2M of flash and 8M of RAM, it might be possible
to put linux on it, but we have to port another bootloader, because we
don't have the sources of the current one.

Have you tried to do some nmap -S to identify if it was running linux or not?

Getting the ARM core to work is usually not a problem. They are pretty much
compatible between each other, like 386 and 486 processors are compatible.
Peripherals are _the_ problem. But ISL3893's UART is 16550-like, mapped in
memory at 0xc00005xx IIRC. So you should be at least able to get the U-Boot
prompt to work with minor modifications.
