Hi Dennis & Jon and once again thanks for your support.
Well Dennis, my first act was to install the IoT 2018 image, as recommended
by Seeed, but not a character was output from HDMI cape, since the first
boot.
Of course me too I was sure that at least a simple graphical iface was yet
present in the OS, but anyway I've installed lxqt as indicated in the Seeed
installation guide, with same no luck.
After a while I've installed the 2020 IoT release (sure a kernel 4.4.x),
and the following history is well known...I've tried your suggestions but
no way to arrange the stuff.
And no, not yet tried the way of the Seeed Community: of course I'll follow
the last suggestions of Dennis, before to approach to Seeed (with no big
hope, let me say...).
If all would fail again I must suppose that the cape hardware has some
fault, or the 1.2 HDMI protocol declared onboard is not suitable here.
Otherwise I can't imagine how, and how longtime, Seeed would continue to
sell an hardware surely NOT Plug & Play knowing the problem.
Get in
touch and stay tuned, in the meantime have both my best wishes for a
(finally..!) happy 2021
Luigi
