Windows 8.1 preview and i.MX28

Hi everyone,

Since Windows 8.1 is coming out in about 2 months, we have loaded up our hardware based on the i.MX28 and connected it to Windows 8.1 Preview and we were very surprised to see it not even recognized by Device Manager. Our USB driver is based on the gadget zero driver, so I also tried the g_zero, g_filestorage, and g_serial, to see if any of those would appear to Windows 8.1 like they do in Windows 7 and none of them work! Very surprising.

I then tried the board in Freescale ROM Recovery mode, and it also doesn't appear!

Has anyone else tried an i.MX28 board on Windows 8.1 yet? I've opened up a ticket, so I'm still waiting on hearing from Freescale support on this, but I think this is pretty important to figure out given that 8.1 is releasing so soon, in 2 months.

The MFG application is verified on WIN7 32bit/64bit and WINXP Professional.
It is not verified on other windows platforms.

The i.MX23, i.MX28, and i.MX508 ROM devices enumerate as HID devices and use

the built-in Microsoft drivers. There are no special considerations needed for these

devices on a 64-bit OS.

Basically MFG sources are available (if needed to adapt it to Win 8) :

Hi, thanks for the response, however, the PC side support of the MfgTool is

not the issue here. It is the fact that the device doesn't even show up to

Windows 8.1 Preview at all, regardless of whether you're using MfgTool or

not. Can you please try to reproduce this?

Looks like the problem relates to USB3 options.

The MFG for i.MX28 on the Web does not support USB3.

Some MFG problems relate to the general USB3 support under OS and issues may be solved,

when USB3 ports are disabled in Win 7 / 8.
