Hello all,

Logistical Updates:

- Board arrived last Thursday

Progress Updates:

- GR. Most of last week was spent digging through gnuradio-runtime to  
understand where we can modify things to allow direct buffer  
manipulation.  
Played around with modifying trondeau’s branch and guruofquality’s  
legacy  
(GR 3.6) branch on inplace buffers so I can learn more about how the  
buffers are modified. On hold for now but please let me know  
suggestions/recommendations or related projects!

- K2. The recommended way to communicate with the keystone is with a  
TFTP  
server since it has NO SD. I was able to setup the environment and get  
into  
a terminal so next step is cross compiling GNU Radio with the help of  
Philip and his expertise in embedded stuffs.

Not much working code yet but it’s coming! Again further details on the  
wiki. I try to update it regularly so I don’t forget steps

Thanks!
