[SOLVED]Use SDCard rather then internal memory - MIkrotik hex s RB760iGS[SOLVED]

Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 2048 246417407 246415360 117.5G 83 Linux partition1
/dev/mmcblk0p2 246417408 249737215 3319808 1.6G 83 Linux partition2

I want OpenWRT to use SDCard partition 1 (117.5G) rather than internal storage of 16MB. Is this possible?

Thanks. Get finally to move overlay to sdcard.
