I'm not familiar with it, but looks like this TechNexion TDM-3730 module has
it's own unique machine ID and requires changes to the kernel to be able to
identify your board. I'm guessing you are trying to use an old 2.6.x kernel
that required a board file for each new platform, if it's not exactly the same
(hence a different ID). Check with the company that produces this board if
they have a kernel or patch available to make it work. Otherwise you better
off asking on e2e.ti.com for how to add new machine ID for your board...
