no output about systemd information

I followed this link to do https://github.com/kraj/meta-musl. This link provides the application of musl-libc library set on OpenEmbedded/Yocto.I added the layer to bblayers.conf and also added TCLIBC = “musl” to local.conf I initialized the environment and then run bitbake core-image-full-cmdline. I got a core-image-full-cmdline-freedom-u540. wic and write to uSD card. Set MSEL to mode 1111. Start HiFive Unleashed development board and get the following output:

But there is no output about systemd information,what should i do?
