which Petalinux version do you use? Uarlite IP right? Look to your srec file and
look at CR-LF and try combinations. I think in latest svn version should work
any combination.

I think that work. Just console doesn't work.
cat linux-2.6.x/System.map | grep __log_buf
0xXXXXXXXX __log_buf

in U-boot md 0xXXXXXXXX


The second test could be if you use emaclite or ll_temac -> try to  connect
through telnet.
