Hi Dmitriy,
I'm afraid we don't have any documentation in Russian. This is the link for the Starter Kit wiki, which leads to available resources: http://processors.wiki.ti.com/index.php/AM335x_Starter_Kit.
For Starterware we have a dedicated forum: http://e2e.ti.com/support/embedded/starterware/default.aspx, where you can ask your questions.
