What is the SoC on the ARM9 board TS-7800?

Question

From here: http://www.embeddedarm.com/products/arm-sbc.php#ts-7800-500mhz-series

The TS-7800 series of single board computers provides 3 times the performance of the TS-7200 series with the same footprint, using a Marvell 500MHz ARM9 SoC.

From here: http://www.mail-archive.com/xenomai@xenomai.org/msg00071.html

The link you quote provides only very vague information like "using a Marvell 500MHz ARM9 SoC" (which can be anything) or "use a recent Linux kernel 2.6" (which means they are plain OLD - recent means v3.4 or later). This may be sufficient for marketing material, but not for answering technical questions.

I found this: http://oz.embeddedarm.com/~michael/support/ts7800.html
But, can't find something related to SoC there.

How do I find out the exact SoC this ARM board uses?

Answer 1

The Technologic Systems website you linked-to says here that :-

The TS-7800 is a RoHS compliant Single Board Computer (SBC) based on a Marvell MV88F5182 500MHz ARM9 CPU

Although this processor doesn't seem to be mentioned on Marvell's website (obsolete, perhaps?), Technologic have a PDF manual here (dated 2008) which described the device as a "Feroceon Storage Networking SoC".

The manual isn't a "newbie" guide for non electronic engineers, but as a software developer, you should find it a useful resource.
