What is the login username and password of freedom-u-sdk?

Hi,
What is the login username and password of freedom-u-sdk? How to configure it? I’m debugging on vc707.
Thank you very much!

The old buildroot version is root/sifive. I don’t know if that has changed.

FWIW, the README.md mentions root and no password.

The root password will depend on what rootfs you are using. The buildroot root passwd was sifive as Bruce mentioned. This was specified in the buildroot config file in the conf directory, before we switched to open embedded. If you are using a Debian or Fedora rootfs with u-boot, then the root password is riscv. That is hardcoded into those root filesystems. If you are using an open embedded rootfs, then the default is no password for root. The current sources default to open embedded rootfs, and the README.md file does say that there is no password for root. This was added September 19.
