Hi Vamsi - It looks like you're doing everything correctly for building
& installing your OOT & GR itself.


If I had to guess, I'd think that, somehow, the 2 argument to "map" is
being provided either directly or indirectly in the "top_block.py"
script & clearly doesn't support iteration & needs to be able to do so.
Since I don't have the code it's kinda hard to say anything more about
what's going on.


I'm not sure how to test the gateway block, whatever it provides.
If you can send me example code off-list I'll give it & try & see
what I can do.


Cheers! - MLD

Hi cdl - Which USRP are you using? USRP1, B200, B210? Might make a
difference ... - MLD
