Links to instructions for installing TrueNAS with front panel display capability on some ReadyNAS

Thanks both.

portalman: the hwmon renumbering is fixable. Don't reference the hwmon numbers at all, look the device up by name. The number changes between boots but the name doesn't:

find_hwmon() {

  for h in /sys/class/hwmon/hwmon*; do

    [ -r "$h/name" ] || continue

    [ "$(cat "$h/name")" = "$1" ] && echo "$h"

  done

}

IT="$(find_hwmon it8622 | head -n1)"

Then write to "$IT/pwm2" instead of a fixed path. Worth retrying for a minute at boot too, since the module can register late. That's what tools/it87-fancontrol.sh in the repo does.

No argument on the rest. An offline box that just serves files can stay on OS6. And I've got nothing for the Pro6, I don't even know if its panel is the same design. If you want to find out, tools/rn-probe.sh is read-only and would tell me what's in there (read the safety note at the top first). A negative result still helps.

Sandshark: can you confirm those CPUs for the 526/8 and 626/8, the Pentium D1508 and Xeon D-1521? If that's right, my README is wrong.

I've been claiming the driver covers the RN526 and RN626X because they share the front board with my 426. That holds for the buttons, which really are on the front board. It doesn't hold for the LCD. The LCD never goes through the front board at all, my code drives its pins on the CPU itself, at addresses hard-coded for the Atom C3538 in the 426. On a different CPU those addresses point at nothing and the display just sits on "Booting...", which is what the RN524X owner reported in June.

I only have the 426 so I can't test this myself. I opened an issue rather than quietly editing the README: https://github.com/riplatt/truenas-rn426-panel/issues/4

If you get a 526 or 626 out of storage, rn-probe.sh output settles it. The CPU model line alone is enough. Run that before the gpio_ich test from my last post, if you only run one thing.
