In this topic I got info on how to disable USB Host functionlity on Colibri VF61 with Win CE 6.
- remove SODIMM 137 jumper, USB_C_DET related circuitry
- set SODIMM 137 as GPIO output and 1
- set registry as shown in below
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\UFN] "Dll"="usbfn.dll" [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBOTG] "Dll"="_otg_vybrid.dll"
If I don’t need Host functionality, can I use SODIMM_129 (which is USBH_PEN for Colibri family) as a general purpose INPUT?
I configured in this way in the bootloader, but with an oscilloscope it seems that Win CE reconfigures it as a low output (standard behavior for USBH_PEN, I think).
Should I set something else on WinCE side?
