Hello again, I decided to try and run the mimo_tx.bin (built from SVN rev 11663) as the s/w firmware and use the Virtex5 board as the "slave USRP2" since this would require almost no changes to the gnuradio side. I'm using u2_rev3_ise10.1sp3_r11370.bin as the FPGA bitstream. When I run the host app ./test_mimo_tx I get the following error and everything freezes up (cannot ctrl-c, have to reboot the usrp2): "usrp2::ctor reset_db failed"
Most people seem to be able to fix this with a firmware update because of some new process in libusrp2 with initialization. If this is the case then it must be something in mimo_tx.c that needs to be updated. Either that or the host app. Any ideas? Might be important: I'm not sure what type of modifications to mb-gcc are imperative for building firmware for the aeMB, but I'm using the standard version that comes with ISE for the vanilla microblaze as I didn't want to mess up the toolchain for standard development.
