Summary: characters is not shown correctly in u-boot jtag console test

Details:

In u-boot jtag console test, run command "echo test", it shows "echo test\n\rtest\n\rbfin>".

For jtag test in kernel, run the same command, it shows "echo test\r\ntest\r\nbfin>". Usually I get "\r\n" at the end of a line in log file, not "\n\r".

Follow-ups

--- Sonic Zhang 2010-10-12 06:13:13

I think both "\n\r" and "\r\n" are valid next line mark in

console. Vivi is better to change the test script to accept both.

--- Vivi Li 2010-10-15 03:56:14

OK, test script is updated in branch 2010r1 and trunk.

Close now.
