If you are using the common Linux components that are provided by AMD perform the following to run an acceleration application on the platform:

  1. To the SD card, write the sd_card.img generated by the Vitis compiler command v++ --package.
  2. Boot the board.
  3. Run the command cd /mnt/sd-mmcblk0p1/.
  4. Run the command source
  5. Run acceleration application. For example, for vector addition, run ./vadd ./binary_container_1.xclbin.

Acceleration application uses Xilinx Runtime (XRT) to communicate with acceleration kernels. To set up the environment for XRT, run This command does the following:

  • It sets the environment variable XILINX_XRT to /usr to allow the application to find the XRT environment.
  • It copies platform_desc.txt to /etc/xocl.txt to inform XRT which platform it is running on.
Note: This was done automatically for embedded platforms in the 2019.2 release of Vitis. Because automatically running may introduce security breaches, common Linux rootfs did no run by default.
Note: If the sd_card.img file has already been written to the SD card and you are only updating the application, you can save time in the debugging phase by copying all files from <Vitis System Project>/Hardware/package/sd_card to FAT32 partition on SD card to replace existing files. The Ext4 partition does not change in sd_card.img.
