sdbuild flow dependency on sdx unclear #754

Closed hzappen closed 5 years ago

hzappen commented 5 years ago

I ran into problems during image building, because the Makefile checks if 'sdx' is present. Before, i ran the setup_host.sh script successfully. The documentation and the readme file in the sdbuild subdirectory do not mention this dependency explicitely.

What am i supposed to install here? I could only find out that sdx somehow belongs to the Xilinx SDAccel application? Is this really neccessary to build a basic image for a custom board, because afaik this software is only available as a paid license version. In version 2.2 of PYNQ is was able to build an image without installing this software.

Thanks, Hendrik

sdx mean SDSoC here. Though it's not total free, you can have a trial in www.xilinx.com/getlicense

To build 2.4 of PYNQ, you need 2018.3 version of Vivado\SDK\SDx\Petalinux, of which the first 3 is involved in SDSoC installation. So it is better to download a single installer of SDSoC.

Maybe we should mention that even SDSoC is not required now; Vivado is required to build z1 and z2 bsp's. That is perhaps all you need.

The image building for non-z1/z2 boards only requires petalinux. The image building for z1/z2 boards needs petalinux + vivado.
