if there is mediaroom running on the box (which is very likely) then you cannot get anywhere with the serial connection.
the only option is to patch the bootloader with JTAG during startup.


Thanks for the info. , but i found out that there's missing a resistor ( R428 ) in the JTAG_Enable Pin on the box that i have here. In this picture : http://www.t-hack.com/wiki/images/1/12/Pinout.jpg there's a 10Kohm for the JTAG-enable ( R428 ).
I will try again with JTAG and see if i can get any results.

I have here also a box  ( KMM 3010-PT )with this processor ( SMP8634LF REV. C ), i tried JTAG but nothing happen, doesn't seem to be working however i was able to get some output with serial port (RS-232). I was wondering if it's possible to do something with this type of hardware ( firmware change ) since these devices are locked to the ISP ?
