That's probably ok. I haven't ever used one of the breakout cables to connect to a SATA connector, but it sounds like SATA cables don't have the built in crossover like the SAS ones do. Matt On 12/07/2009 11:57 AM, Charles Irick wrote: Thank you for the fast reply. It looks like I need th

Thank you for the fast reply. It looks like I need the SATA fanout connectors to be the host in this case because pin 2-3 are TX for the SATA port. Would there be any issue having the mini-SAS as the target? (part: iSAS-7P88-U) Charles On Mon, Dec 7, 2009 at 2:29 PM, Matt Ettus wrote: > On 12/07

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
