Is eMMC on Orande PI plus accessible from the system running from a SD card?

It doesn't seem so, as only SD card volumes are mounted:
[root@OrangePi linux-3.4]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p2   15G  4.7G  9.3G  34% /
/dev/mmcblk0p1   63M   53M   11M  84% /media/boot

Is there a way to access the eMMC at the same time as the SD card so that it could be worked with from the running system?

sudo fdisk -l

here is an output corresponding to my eMMC:

/media/root/57f8f4bc-abf4-655f-bf67-946fc0f9f25b2 - is my mount point of the 5G partition at eMMC

I’m impressed, I have to admit. Actually rarely do you encounter a weblog that’s both educative and entertaining, and let me tell you, you’ve got hit the nail to the head. Your thought is outstanding; the catch is something inadequate individuals are speaking intelligently about. We are happy i always found this during my search for some thing relating to this.        radiofrequency facial machine
