Andrew Karpenkov andrew.karpenkov at gmail.comAlex, 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.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.
