[Discuss-gnuradio] TVRX2+USRP (serial > 500) 'invalid EEPROM contents' problem

[Dmitry Shatskiy]

Hi,

We're using two older USRP boards:

1) Rev. 4.5, Ser. #3542,
2) Rev. 3, Ser. #290 with a clocking scheme modified according to the http://gnuradio.org/redmine/projects/gnuradio/wiki/USRPSerialBelow500 .

We're also using a BasicRX daughterboard with both of these motherboards and have no problems receiving 150 MHz signals using our code.

We were planning to use the newer TVRX2 receivers for the 400 MHz signals so we purchased a couple of TVRX2 Rev. 1.1 daughterboards. No changes were made to them. After plugging any of the two TVRX2 daughterboards - either in addition to BasicRX or separately in any of the receiver slots of any of the two USRPs - and trying to execute our code (or any other basic code like usrp_benchmark_usb.py) we get a standard error message:

> Warning: Treating daughterboard with invalid EEPROM contents as if it were a "Basic Rx."
> Warning: This is almost certainly wrong... Use appropriate burn-*-eeprom utility.

We've tried three different ways of installing the GNU/Radio and UHD:

1) Installing GNU/Radio 3.2+UHD as a binary package (from http://gnuradio.org/redmine/projects/gnuradio/wiki/DebianPackages) on clean Ubuntu 11.04.

2) Installing GNU/Radio 3.3+UHD on clean Ubuntu 11.04 following the instructions from http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall#Building-GNU-Radio-on-Ubuntu-Linux

3) Using the Marcus Leech's script (from http://www.sbrac.org/files/build-gnuradio) to install GNU/Radio 3.3+UHD on Ubuntu 10.04 LTS (previously upgraded from Ubuntu 8.10)

 

All three systems receive 150 Mhz from BasicRX beautifully and produce same error message after trying to access the TVRX2.

 

With BasicRX in RXA slot and TVRX2 in RXB slot the uhd_usrp_probe output is as follows:

linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.002.003-1df3e9b

If the solution requires burning the EEPROM, please advise on the steps - we weren't able to find a step-by-step procedure.

 

Any help is greatly appreciated.
