Regarding the recent PYNQ ZCU208 build that’s available on github, we have a need to have the usp_rf_data_converter appear in the PetaLinux device tree. Currently, when PYNQ 3.0.1 boots, the usp_rf_data_converter does not appear in the device tree. In order to use the APIs in the libxrfdc.so library directly (e.g. from C), the usp_rf_data_converter device needs to appear in /sys/bus/platform/devices. Can I just edit the .dtsi file in github (/ZCU208/petalinux_bps/meta-user/recipes-bsp/device-tree/files/system-user.dtsi), add the usp_rf_data_converter and rebuild Petalinux? The petalinux-config files aren’t in github (it would be nice if they were), so I can’t start from there. The usp_rf_data_converter entry in the user.dtsi file would look something like this:
usp_rf_data_converter: usp_rf_data_converter@80000000 { clock-names = "s_axi_aclk", "m2_axis_aclk", "s0_axis_aclk"; clocks = <&zynqmp_clk 71>, <&misc_clk_0>, <&misc_clk_1>; compatible = "xlnx,usp-rf-data-converter-2.6";
