Hi, Thank you. Tx/Rx on the old Flex2400 using the usrp2 is now working. On 01/09/2010 21:41, Jason Abele wrote: On Wed, Sep 01, 2010 at 03:08:53PM -0400, Marcus D. Leech wrote: On 09/01/2010 12:51 PM, Jason Abele wrote: I'll need to do some re-soldering and burn-db-eeprom with USR

You are using a very old RFX2400 which is configured with its own onboard oscillators instead of using the master oscillator from the motherboard. You can reconfigure it to work with USRP2 by following the directions under "Synchronizing all daughterboard LOs" here: http://gnuradio.org/redm

Hi Marcus, I get exactly the same behaviour. I have finally traced the problem to an old Flex2400 using an internal clock rather than the usrp2 clock. I'll need to do some re-soldering and burn-db-eeprom with USRP1 and hopefully this should fix the problem: http://gnuradio.org/redmine/wiki/1/

Hi, We are currently experiencing Transmit and possibly Receive problems with the USRP2-Flex2400 boards. - The USRP2 is detected: # find_usrps -e eth0 00:50:c2:85:32:73 hw_rev = 0x0400 - The latest firmware and Raw Ethernet FPGA images have been written onto the SDRAM: u2_rev3-20100603.bin,
