Choose the approved EMMC seat,don’t use the third-party seat,the sign of the chip should be in the direction of lower left.(EMMC must be planted beads,and be cleaned up or it will make the mistake easily)  Clickto choose the printing letter,the default is EMMC_AUTO_4BIT.Can also input “EMMC”in the “Enter chip printing”.  EMMC_AUTO_4BIT:Slow-speed reading,but with high stability, higher successful rate,software default. EMMC_AUTO_8BIT:High-speed reading,suitable for most of the EMMC chips. If read and write on line,please choose EMMC_AUTO_ISP. Click “Setting” then the dialog box in the middle pop up.  The left is the 5 partitions of EMMC,the “USER” is the user area,“RQMB”is the encryption area,the data in it can not come out so don’t have to be chosen. The right is VCCQ power supply choice,it’s 3V generally,very few chip need to choose 1.8V. The success hint of reading chips:  The software will create a folder automatically after EMMC already read the data,there will be the data of corresponding area,it’s alright to save the whole folder.  (When the capacity of EMMC is more than 4G,the file read be divided into 2 parts automatically,it is normal that there will be 5 files.) When writing EMMC,drag just an icon into the display area of software then all the file will be loaded to the software.
