I wish the Sony protocol was open source. It is impossible for a hobbyist to work with SLVS-EC.

- kanetw 4y agoI can't say much because NDA, but it's not the most difficult protocol to reverse engineer. Also, if we decide to make our own RX IP for it, there's a good chance I can open source it. Will have to have a lawyer look over the licensing/NDA terms to make sure we're not messing anything up in that case.
- snops 4y agoIts (presumed) competitor, MIPI-CSI is not open source either. SLVS-EC looks easier to interface with an FPGA at least, presumably the voltage levels are closer to standard, unlike MIPI D-PHY's exotic dual level switching that either requires an external IC, a passive resistor network of borderline compliance, or an FPGA (e.g. Lattice CrossLink) with the correct special inputs.
- kanetw 4y agoSLVS-EC has some very minor issues when interfacing (DC offset compliance) which requires a hack in detecting when the link is up. And yeah, MIPI D-PHY is a royal pain unless you have native support (Xilinx, Lattice, Intel Agilex 5). C-PHY even more so. C-PHY is so incredibly fucked up.
