no output about systemd information

[TONG369]

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?

In a meta-musl Yocto layer I would expect that systemd is not used at all. Did not look at the sources in detail, sorry. Last time I used Yocto in 2016.

[jsarenik]

Anyway. Note that there was no commit in this repository since Feb 10 2016. So I would highly suggest using it only in case you need to rebuild a system that was made for environment back then and you have all the needed dependencies.

[kraj]

@TONG369 if you are using latest yocto release then you do not need meta-musl because musl is already merged into core.

[TONG369]

I removed the meta-musl package according to your suggestion and use the musl that comes with yocto. However, this error still exists, still can't get into the console. How should I do to solve this problem ? I am looking forward to your reply! @jsarenik @kraj @armcc @tprrt
