HI,
Hi.. I am trying to rebuild FINN using build_custom command for resenet50 targeting Alveo U250 board.

Vitis - 2020.1
Ubuntu - 18.04
Board - Alveo 250

I given following commands,
export FINN_XILINX_PATH=/tools/Xilinx/
export FINN_XILINX_VERSION=2020.1
export PLATFORM_REPO_PATHS=/opt/xilinx/dsa/
export XRT_DEB_VERSION=xrt_202010.2.6.655_18.04-amd64-xrt
export VITIS_PATH=tools/Xilinx/Vitis/2020.1
FINN_EXAMPLES=/home/test/finn-examples
./run-docker.sh build_custom /home/test/finn-examples/build/resnet50/

I am getting assertion error - Vitis .xclbin file not created- in the 11th step (bitstream generation). Herewith I am attaching terminal screen short as well as V++.log file error.

Thanks in advance!!
