Hello all,

I plan to add metadata in my custom RFNoC block, reading the RFNoC specification I noticed that the rx_streamer and tx_streamer handles metadata. my question is:

Is this the same metadata specified in the context CHDR messages? if it is not, how can we read at the host side, the metadata added in the rfnoc block?

Thank you.

Hi,

metadata reading/writing in UHD is currently not implemented. If you think
this is a relevant feature, reach out to your NI USRP rep to bump its
priority.
