Executable Usage:
To execute single file for decompression :
./build/xil_zlib -cx ./build/xclbin_<xsa_name>_<TARGET mode>/compress.xclbin -c <compressed file_name>To decompress multiple files :
./build/xil_zlib -cx ./build/xclbin_<xsa_name>_<TARGET mode>/compress.xclbin -cfl <files.list><files.list>: Contains various file names with current path
The usage of the generated executable is as follows:
Usage: application.exe -[-h-d-sx-l] --help, -h Print Help Options Default: [false] --decompress, -c Decompress --decompress_xclbin, -cx Decompress XCLBIN --file_list, -cfl List of Input Files
