Hi all
New version of Matrix V23 using four pins switch which is more good than before, the switch control can be use like this
EMMC 1111
SD2 1000
SD3 0100
For the older version matrix using 8 pins switch control can be use like this:
EMMC 11100110
SD2 10000010
SD3 01000010
if your matrix is the first version of matrix you can boot from SATA
SATA 00100110
Thanks
Kind Regards
steven
