RE: [microblaze-uclinux] opb_mdm JTAG Uart -- No input

["Vasanth Asokan" <vasanth.asokan@xxxxxxxxxx>]

It is recommended to connect Hyperterminal/Teraterm or any standard
terminal program to the MDM JTAG UART rather than the simple TCL
terminal that XMD opens. This can be done by issuing the command,

terminal -jtag_uart_server <portno>

This opens up a TCP port at <porno> to which you can connect your
terminal program. Thus you can get standard terminal behavior via MDM
UART. Please try this to see if it helps.
