Hi Gerhard,I received your comments via github regarding my Kingst LA2016 open firmware submission [1]:

No, the sigrok-firmware repository is not a good location for the source code. It contains binaries only by design. If you got OpenSource firmware (new implementations or extensions to existing setups) then consider the sigrok-firmware-fx2lafw repository.
The sigrok-firmware repository was suggested by a member of your team, it seemed reasonable to me. Your suggestion of the sigrok-firmware-fx2lafw repo makes no sense at all, being for unrelated hardware and with very different firmware goals. Perhaps a new common sigrok-firmware repo would be better, containing both projects.

Am saying that without having looked at any other part of your submission. Because firmware extraction from the vendor software is required in any case to get the FPGA netlist blob. Have been using mainline sigrok in combination with vendor firmware from different v3.5.x versions (3.5.1 to 3.5.5 which all contained the same blobs). So no feedback from me on your MCU firmware here.
Are you saying that sigrok, an open source project, would prefer closed oem firmware over an open source drop in-replacement? My firmware has been well tested on LA1016 and LA2016, provides insight to the USB protocol and requires exactly zero extra user effort to install and use. Futhermore, it is a stepping-stone toward an open LA with high sampling speeds, using easily available and modestly priced commercial hardware. This is something sigrok currently lacks.
As I mentioned earlier, I have also made progress on an open fpga bitstream for Kingst LA2016/1016 and small captures can be made from PV using the Kingst driver. The ddr2 sdram controller and phy still need to be implemented but I see no point in continuing if using the oem firmware and bitstream is preferred by sigrok.
