I haven't got it set up, but my numbers say 2 lanes. hdmi_line_freq = 148500000 / (1920+528+44+148) = 56250 (56.250kHz matches HDMI spec for VIC 31). csi2_data_rate = 1920 *...

waveshare35c is not an overlay that forms part of our kernel tree, therefore I'm afraid we can offer no support for it. You're also using ``` hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt...

@nsc-de Nice diagrams, but a couple of comments. The Pico runs on 3.3V, but the standard MAX485 is a 5V device. You want to be using a [MAX3485](https://www.analog.com/en/products/max3485.html) when running...
