Running on FPAG U55C

[honweg4-jpg]

I installed the 32-bit and 64-bit toolchains separately according to the project tutorial, and generated and programmed the bitstreams for the FPGA——u55c platform in the build directories respectively, referring to fpga_setup.md. (My XRT version is 2025.1, and I have not modified any configuration files such as VX_config.vh) Running the tests in the project on the board in both the 32-bit and 64-bit build directories, the demo passes, but /opencl/conv3, /opencl/vecadd, and others all show the computation values as zero.

1. I would like to ask why this situation occurs?
2. When implementing Vortex on Xilinx FPGA, in which configuration file is the operating frequency modified?
