It seems there is some problem … what does this messages mean ??

These are more like warnings, mmc1 is related to the SD card and persistent storage, the BT may have happened in case of some miscommunication or some paired device going out of range. the HDMI errors only should be worried about if you’re using it and the audio is not working.
