Ezynq

Decription

Ezynq project is started to create a bootloader for systems based on the Xilinx Zynq SoC without the inconvenience of the non-free tools and/or files. The goal is not just to "free" the code, but to provide users with the higher degree of flexibility in fine-tuning of the configuration parameters.

"Free" the code part

Ezynq addresses the potential legal problems with distribution of a product/software based on Zynq platform:

• FSBL is under Xilinx's copyright
• The current (2014/02/23) official SPL implementation in the u-boot-xlnx master-next 54fee227ef141214141a226efd17ae0516deaf32 branch is FSBL-less but it requires to use the files (ps7_init.c/h) that come under Xilinx's copyright which makes u-boot noncompliant with its GPL license.

• For a new board you still have to run an extra Xilinx program to generate ps7_init.c/h.

• u-boot-xlnx master-next branch is removed long ago - so the link above is broken

as of 2016/06/25...

• ezynq depends on original u-boot instead of u-boot-xlnx

Supported boards
