Hi, I'm comparativley new to Vivado and FPGA programming. I wanted to test this framework and just tried to run the example dnnweaver2-tutorial-notebook. I ran into some problems and tried to figure out what's wrong. I got stuck at Part 1 Step 3 of the notebook with an IOError during the initialization of the FPGAManager - "No such file or directory: '/dev/xdma0_user'". Well I see that this file is not there - but where does it come from or where do I generate it? Do I have to run the Vivado part described in the Hardware Readme first?

Hi! I ran into the same situation as yours. Have you solved this problem? As far as I know, the file /dev/xdma0_user is the interface between the dnnweaver2 and the hardware, and if you connect the FPGA board and load the driver correctly, it should be in there. However, I just have /dev/xdma0_h2c and /dev/xdma0_c2h and some other xdma0_events files in this path. Do you know what's going on?
