Alex, please see my comments below.

I found this link:

> Is this information is correct?

Correct, but not for UmTRX. UmTRX architecture based on N2x0 USRP, wich
haven't  ram_loader and sd card.

 I don't understand, how .rmi code processed, and how this code executed.

Build instructions for ZPU software (including bootloader.rmi) described
here <https://code.google.com/p/umtrx/wiki/BuildingUHD>.

mkdir <UHD-dir>/firmware/zpu_build

cd <UHD-dir>/firmware/zpu_build
export PATH=$PATH:<path-to-zpu-elf-gcc>

cmake ../zpu
make

After this, you need to update the ZPU bootloader in fpga project:

cp <UHD-dir>/firmware/zpu_build/usrp2p/bootloader/bootloader.rmi
<UHD-path>/fpga/usrp2/top/N2x0/bootloader_umtrx.rmi

And now, you can compile fpga project:

cd <UHD-path>/fpga/usrp2/top/N2x0

make UmTRX

Where (*.v file)clock description i can found?

All clocks are forming in
u2plus.v<https://github.com/fairwaves/UHD-Fairwaves/blob/fairwaves/umtrx/fpga/usrp2/top/N2x0/u2plus.v>file
(pll_clk.xco and pll_rx.xco).

 For which purposes ram needed?

RAM is needed to run programs by ZPU.
