john@john-virtual-machine:~/Vitis/Vitis/2019.2/platforms$ sudo apt install ./xilinx-u200-xdma-201830.2-2580015_18.04.deb
Please flash card manually by running below command:
sudo /opt/xilinx/xrt/bin/xbutil flash -a xilinx_u200_xdma_201830_2 -t 1561465320
john@john-virtual-machine:~/Vitis/Vitis/2019.2/platforms$ sudo apt install ./xilinx-u200-xdma-201830.2-dev-2580015_18.04.deb

第二章 操作软件
john@john-virtual-machine:~/vitis/getting-started-rtl-kernels$ vitis
在这里插入图片描述
在这里插入图片描述
package_xo -xo_path /home/john/vitis/getting-started-rtl-kernels/rtl_ke_t2/vivado_rtl_kernel/Vadd_A_B_ex/exports/Vadd_A_B.xo -kernel_name Vadd_A_B -ip_directory /home/john/vitis/getting-started-rtl-kernels/rtl_ke_t2/vivado_rtl_kernel/Vadd_A_B_ex/Vadd_A_B -kernel_xml /home/john/vitis/getting-started-rtl-kernels/rtl_ke_t2/vivado_rtl_kernel/Vadd_A_B_ex/imports/kernel.xml
第三章 问题及解决
- rtl_ke_t2文件找不到
/home/john/vitis/getting-started-rtl-kernels/rtl_ke_t2_system/rtl_ke_t2_system
这是因为没有build, build即可
- libstdc++.so.6: version版本不对，将版本调至libstdc++.so.6: version
/home/john/vitis/getting-started-rtl-kernels/rtl_ke_t2_system/rtl_ke_t2/Emulation-HW/rtl_ke_t2: /home/john/Vitis/Vitis/2019.2/lib/lnx64.o/Default/libstdc++.so.6: version `CXXABI_1.3.11’ not found (required by /opt/xilinx/xrt/lib/libxilinxopencl.so.2)
sudo find ./ -name libstdc++.so.6.0.25
./xic/lib/lnx64.o/Ubuntu/18/libstdc++.so.6.0.25
删掉软链接和libstdc++.so.6
sudo cp /home/john/Vitis/Vitis/2019.2/lib/lnx64.o/Ubuntu/18/libstdc++.so.6.0.25 /home/john/Vitis/Vitis/2019.2/lib/lnx64.o/Default/

sudo rm libstdc++.so
sudo ln -s libstdc++.so.6.0.25 libstdc++.so
出现第二例，同上修复错误即可。
sudo cp /home/john/Vitis/Vitis/2019.2/lib/lnx64.o/Ubuntu/18/libstdc++.so.6.0.25 /home/john/Vitis/Vitis/2019.2/lnx64/tools/gcc/lib64/
