Blackfin JTAG console: no output in u-boot and in Linux Kernel

Hi,

 

I've a problem configuring the JTAG CONSOLE feature of U-boot and Linux kernel: I'm obtaining no output in both modes.

I have followed with attention all the guides in http://docs.blackfin.uclinux.org , expecially these:

 

http://docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:jtagconsole

http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:jtag-console

 

I'm using gnICE+ JTAG Adapter, which I think is well configured because I'm using for debug purposes the couple gdb<->gdbproxy without any problem. Gdbproxy creates correctly the two ports on the host linux PC:

I'm using these toolset:

U-boot: 2010.06 (ADI-2010R1-RC2)

uClinu-dist: 2010R1, Nov. 17, 2010

 

JTAG Console output on host: jtagconsole helper, netcat and telnet: no one works.

 

 

Thank you for your help!
