Problem with DBSRX rev 2.1: "No class defined to handle daug

GNU Radio

I have DBSRX rev 2.1,
after burning eeprom with the command ./burn-db-eeprom -t dbsrx2 -A -f
an error appears when I try to use the daughterboard
“ValueError: No class defined to handle daughterboard (dbid = 13)”

Similar problem was addressed in
http://www.nabble.com/Problem-with-RFX1800:-“No-class-defined-to-handle-daughterboard”-t2068897.html
but in my case rebuilding with the latest version didn’t solve the
problem.

Any suggestions ? Below is detailed listing of the output.

It works ok now, thanks Matt.

I burned eeprom because earlier I got a message “Invalid EEPROM
contents”
It seems now that it wasn’t necessary.

You don’t need to burn the eeproms – I do that when I test the boards
before shipping.

You need to re-burn your board as a dbsrx, not a dbsrx2. There are no
dbsrx2 boards.
