FYI, rfnoc-devel is up to date with master, but currently has an issue with respect to the E310. This particular issue mentioned above, however, is resolved. > Unfortunately, my simple radio code to transmit (even bypassing all DUC > operation and talking to the radio directly, expecting underflows) was > not successful at all.

One thing you can do is use something like tx_samples_from_file, and specify skip_duc=1,skip_dram=1 in the device args, and it'll tx straight to the radio. If you want to do this successfully, you need to resize the input buffers to the radio block. -- M _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
