We are using MCHStreamer boards for the characterization of MEMS microphones which output a PDM signal. We are currently using two boards, one programmed with the "MCHStreamer_16i0o_sn19_PDM_v1.6_up.bin" Firmware and one with the "MCHStreamer_16i0o_sn20_PDM_v1.6_up.bin" Firmware. This works fine so far. We would like to upscale the setup to use 4 boards. This failed so far and I believe the reason is that I cannot flash the additional boards with another serial number as there are only two Firmware variants available for download. When we tried to setup two boards, we had the exact same issue (I think it was a "Invalid Input Device" error) until we flashed distinctive variants of the firmware. So my question is: would it be possible to obtain 2 more Firmware variants for PDM, e.g. with serial number 21 and 22?
