Hi, Are we correct that bootloader.rmi stored in "usrp2/top/N2x0/bootloader.rmi" is outdated and we should use one, which is generated during ZPU firmware compilation, it serves a different purpose? http://code.ettus.com/redmine/ettus/projects/fpga/repository/revisions/master/changes/usrp2/top/N2x0/bootloader.rmi -- Regards, Alexander Chemeris.
