I built ti-processor-sdk-linux-am57xx-evm-03.00.00.04.
And ran AM572xEVM by TFTP and NFS.
The minicom display following.

Arago Project http://arago-project.org am57xx-evm ttyS2

Arago 2016.05 am57xx-evm ttyS2

am57xx-evm login: root

Login incorrect
am57xx-evm login:


I type 'root' for login.
But, Login error occurred.


And I try SSH login to AM572xEVM.
On the other hand, I succeeded in login by 'root' user name.


Why dose it fail?
I want advice.
Thank you.

    Hi,

    Are you working with TI AM572x GP EVM or a custom board? If you're using the EVM, do you have problems with the prebuilt images?

    Can you share the content of /etc/shadow?

    Best Regards,
    Yordan

    Hi,

    I'm having almost the same problem, except I cannot login using  root or 'root' at the am57xx-evm login: prompt.  In each case, it says login incorrect.

    I'm booting via a network boot.  My NFS server doesn't have a shadow directory under /etc..

    Thanks,

    Jeff

    correction, I do have an /etc/shadow file.

    The contents of the shadow file on the host FS over NFS appear to be consistent with the original file contained in the sdk zip file (ti-processor-sdk-linux-am57xx-evm-03.01.00.06)..

    Also, I'm not able to SSH into the EVM, but am able to ping it when the arago prompt comes up on console.

    When SSHing, I get, ssh_exchange_identification: read: Connection reset by peer.

    Thanks!

    Also, I started with the pre-built binaries when installing the SDK. I ran the startup script, and allowed that to unpack the targetNFS.

    ** I have not yet attempted to build/compile any of the components in the SDK on my own ***

    ** Does it matter if I start with the pre-built binaries/fs in the SDK or do I need to re-build the kernel and FS first before attempting to deploy it to the target??

    ** FYI - I was able to get past the login as root issue by adding "no_squash" settings to the exported directory in /etc/exports **
