Vitis-Tutorials XRT Error: No Device Found

Hello everyone,

I followed steps which is example of vitis-ai for zcu104, however all steps passed until putting the sdcard to the board.

In version 2020.2 https://github.com/Xilinx/Vitis-Tutorials/blob/2020.2/Vitis_Platform_Creation/Introduction/02-Edge-AI-ZCU104/step4.md,

When the step 2 of test 2 have been run the code as ./vadd binary_container_1.xclbin, i would get following error on board interface console

[XRT] ERROR: No device found
Error: Unable to find Target Device [XRT] ERROR: device is nullptr

thanks for answer

Hi, @nrllhclb From my experience, this kind of error "[XRT] ERROR: No device found Error: Unable to find Target Device [XRT] ERROR: device is nullptr" may be caused of lacking ZOCL node which is a device tree node to be used to bind the ZOCL driver. Without this driver, XRT can not communicate with the PL side IPs. As a result that kind of error would occur. So please convert your system.dtb file to system.dts file to check whether it has the ZOCL node or not. If there is no ZOCL node please refer to step2 to update the DTS file.
