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-cl...
but in my case rebuilding with the latest version didn't solve the
problem.

Any suggestions ? Below is detailed listing of the output.

Pawel

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.

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.
