TRK-MPC5634M (rev B) - no virtual serial port

[jonr]

I have this MPC5634 board - great deal.  One issue is that no virtual serial port appears in Windows.  I upgraded the Windows drivers, no change.  I tried to update the OSJTAG firmware, but putting a jumper on J35 (OSJTAG BootloaderEnable) causes the board to not power up at all.   Any suggestions?

FreeScale support hasn't been any help either.  I'll probably have to add a real serial port with a USB to RS232 ttl adapter.

P&E support was helpful in using a Multilink to upgrade the OSBDM firmware (J35 didn't work) - I now see the serial port in Windows even if I don't see any characters coming in.

Unfortunately, most Windows program do not see these virtual serial ports.  You can run "P&E Terminal Window Application" but nothing else.   Evidently virtual serial ports are pretty much worthless.
