Dear all,

After following [1] (testing OOT gain block from example code),
uhd_usrp_probe outputs:

[...]
[WARNING] [RFNOC::BLOCK_FACTORY] Could not find block with Noc-ID 0xb16, 0xffff
[...]
|   |   * 0/Block#0
|   |   * 0/DDC#0
[...]

and in C++:

auto gain_blocks =
graph->find_blocks<rfnoc::example::gain_block_control>("");

is empty, while:

rfnoc::example::gain_block_control::sptr gain_ctrl =
graph->get_block<rfnoc::example::gain_block_control>("0/Block#0");

failed with:

"Error: LookupError:
This device does not have a block of type
rfnoc::example::gain_block_control with ID: 0/Block#0"

Does anyone know what am I missing?
