Hi,
The custom board which we have built with AM3894 processor keep having the USB D+ line going high and the USB D- stays at low right after u-boot, when it is at kernel mode where some form of configuration are going on.
From what I have mentioned above, it looks to me that our CPU is behaving more like in device mode rather than host mode. Upon checking with the linux configuration menu, it shows that the build is set to compile the USB code as host mode. This kernel code was brought over to run on the EVM but does not exhibit any problem of detecting a USB device.
Anyone has seen this before, care to share with me your findings?
Thanks and regards,
