Dear all,
My company just decided to throw away their "room manager" system called EVOKO room manager ERM1001 (ARM32 processor). These devices are really nice as they act as a wall mounted tablets to control meeting booking.
After some investigation I realized these equipment's are based on Windows 5 CE. I wanted to transform them in IOT controls with "homme assistance".
But sadly, even installing a web browser seems to be mission impossible. I have already tried Openamini5 , but when i run the program I've the error message: "Operamini5 is not a valid CE application", well, probably a dll issue or a non compatible application with my system.
I read some post advising the use of "zetakey" browser (trial version) for Windows CE devices but for some reason I can only open their demo webpage , I cant browse freely, not even open a google page web, weird.
I have several of these devices (you can google to see them) and I'm willing to send you one for free if someone can help me to build a new Windows CE with the missing dlls, or to successfully launch a browser, or to build an app to access Homme assistance, or so propose another interesting solution (maybe install raspbian on them?)
Thanks and Regards

Seems to be some sort of ARM9 chip, so probably either the ARM9TDMI (ARMv4T) or the ARM9E (ARMv5TE) the latter of which would make it XScale equivalent.

Your best bet is likely to try and get hold of the missing Internet Explorer files and see if you can get them to register.

Indeed it has a Samsung ARM926EJ-S processor (32/16-bit RISC architecture). Thanks for the advise I will try to obtain the dlls for IE. Else, do you think I could install RISC OS maybe? I dont have much experience with Windows CE. I dont know if I can force the device to boot from USB for example.
Regards

I have no specific idea about the device, but as a general rule, you can run anything you like on it, provided you are able to write the necessary boot code onto the device... which likely requires ASM in most cases (or create a boot strap function for it, usually in C), plus arrange a driver package for it. In the vast majority of cases, this renders it outside the ability of all but the most low level and die hard users.

If you can ascertain what SOC or BSP it is based on, you might get lucky and find that it already exists. If you can find a BSP, you could even in theory recompile a new CE image for it with everything you want.
