Hello,
I am new on dm6446 and I meet a problem that I can't use root account to login dm6446evm.
My host OS is Ubuntu 9.10 and use the latest montavista toolchain from TI website.
I had read the link http://e2e.ti.com/support/embedded/f/354/t/102161.aspx and tried all the suggestions, but the problem is not resolved.
Please help me because I have been stuck with this problem for weeks.
The following is the message output from dm6446evm:
