I tried to make a start on kernel 4.8 yesterday but got interrupted when I'd only just started downloading the source. I wonder if we need to move the arm_bx_hook_init to earlier in the boot, I was going to try it at arch_initcall and see if that might help. I don't know if you already tried that Stefan?

@Joval: I'm not sure if we'll be able to get the suspend working or not...

Re the "white screen on shutdown issue" - how does that look like? ....

Hi Timob0 : Thanks for your response. The suspend issue is not a priority...more icing on the cake...gotta bake the cake first ie, kernal work, sound work, usb etc. I just appreciate there may be that option someday. My primary interest is in getting usb working because I want to get one of those mini wifi dongles working...there are linux drivers available. I just received one of these https://www.amazon.com/TP-Link-wireless-network-Adapter-SoftAP/dp/B0...

The white screen is, as you point out...really just an issue with the incorrect contrast setting --- something to do with, I assume, the bios or bootloader ( I'm guessing here as I know little about WInCE bios or bootloader) and not the winCE registry because the latter should revert to normal screen if restoring from backup...as registry is restored therein. I wonder if there is a registry tweak that might restore normal contrast... I'll have to take a look and play around with registry settings and see if anything changes. Simple enough, I'm just bouncing the idea off you for pointers as to where to look... in the registry ?

Hi Joval,

I'm on board with the USB dongle. I found some on Amazon which support both bluetooth and Wifi and are really tiny. So I asked Stefan for the soldering points on the motherboard to wire up the USB. I'm thinking of dismantling the USB dongle and connecting directly to the mobo with wires as short as possible to minimize electrical issues.
In case that works it would give built in Wifi/BT freeing up the PCMCIA slot. Re. the drivers, munchhausen is making an effort to get a more recent kernel running, this should help with the USB/Wifi stuff I think.

Re. the brightness/contrast setting, what I've seen is that if I remove all power sources, leave it for a few seconds and power it up again, the screen is back to normal. I believe that Linux leaves the screen in some state on shutdown which is unexpected by the factory installed software. Obviously that state is cleared back to normal when the device is unpowered. Also I don't think it's fixable in WinCE since that isn't running yet when cold starting the machine and, when I reach CE I can't really set the contrast/brightness back to normal values, since the sliders on the control panel don't seem to have much effect then. However, navigating to the linux loader and bringing Linux up again gives normal brightness/contrast there.

Cheers,
timo
