how to cross-compile XRT for edge #6143

Open oimasa5 opened 2 years ago

oimasa5 commented 2 years ago

I referred to https://github.com/Xilinx/XRT/issues/2841, but it seemed to be about self-building for the edge. I would like to know how to cross-compile XRT for a ZCU102 board using Ubuntu on an x86 machine without Petalinux. Is it possible to make for edge by adding the -driver option to build.sh in build directory?

Add the -driver option to build.sh, change CPU = uname -m to CPU = aarch64, and ran ./build.sh -driver.

The following error occurred

It sounds that you did not define the FPGA manager options for the Linux Kernel. And, the ZOCL module requires a Xilinx linux kernel, linux-xlnx, to build . Mainstream kernels doesn't provide the suitable fpga-manager interfaces over edge boards (like zynqmp).
