We have incorporated the EMX module onto a base board that we have developed but I am currently unable to talk to the bootloader via the USB. We seem to have all of the JTAG, reset, and USB signals configured in the same fashion as the development board (which does work). Basically when I connect the USB port the PC does not see it at all. We are not user Ethernet. Could it be that the Ethernet is preventing the board from running? Is there some way the pins should be configured? Does anyone have any tricks to see if the processor on the board is in fact running (since it is a BGA there is no easy access to the pins)?
Thanks for any help anyone can provide in getting our board to power on.
