SD Card not Detecting


I installed ubuntu mate on SD card and after that installed the OS to emmc through USB drive through DD, and formatted the SD Card.

Now i am able to boot from emmc, but if sd card is installed then it doesn’t boot, and if i boot and then insert the SD card it is not showing in fdisk

What is the procedure to enable the sd card because after installing ubuntu mate only 400MB space is remaining and need to store the video files for operation

No buddy and there is no support from @sinovoip also
