6140 - Crosslink: Is there any CSI-2 test pattern generator?
In Crosslink IP, Lattice do not have color bar pattern generator except for cmos-to-dphy IP but you may try to check MIPI CSI-2 Transmit Bridge Reference Design for other Lattice FPGA devices. Here's the link: https://www.latticesemi.com/products/designsoftwareandip/intellectualproperty/referencedesigns/referencedesign03/csi2tx
User may check on the documentation section 'Reference Design'. There are a lot of project folder but user may try to explore for instance MachXO3 YUV422 8b 4L. Please find colorbar_gen.v under RTL folder for guidance and refer to top.v on how it was instantiated. This section should aid user in generating a CSI-2 test pattern.
