I'd rather not change the source directory since that's probably less clear for people newer to this code moving forward... https://github.com/kratsg/meta-l1calo/commit/169090e527a5f350ff4d9649bcdbd136a97def2e *Slight question: how does it know to look under files/<MACHINE>/*.dts if I only append the "files/" or "boards/" as an extrafilespath?* Now when I run this, I found a few interesting things: - only works with windows-based line-endings (CLRF screws this up) - I get a complaint about the system.dts file ( https://github.com/kratsg/meta-l1calo/tree/master/recipes-bsp/device-tree/files/gfex-prototype3) which is interesting, but maybe expect. This is fine if I combine both of my dts files here -- but I should point out that this was automatically generated from Xilinx, so I wonder why there are two dts files.
