Alex, please see my comments below.
I found this link:
http://novelflash.com/wiki/index.php?title=USRP2_HDL_Primer 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.vhttps://github.com/fairwaves/UHD-Fairwaves/blob/fairwaves/umtrx/fpga/usrp2/top/N2x0/u2plus.vfile (pll_clk.xco and pll_rx.xco).
For which purposes ram needed?
RAM is needed to run programs by ZPU.

Hello, Andrew!
Thanks for links, i have it already.
I needed for fpga project description(architecture & etc).

Hopefully, not too many questions :)
Thanks for your time!

Hello All!
Where i can find information about fpga and firmware architecture?
I will be grateful for any information :)
