Flash Memory Read-Write test
Tiktoshi Hello, there are already "NAND Test" in UFi eMMC ToolBox for such task. Kindly checked it there. B.R
Tiktoshi there is bad block management in the eMMC Controller, all the spare and ecc data is handled by the controller. There is smart or health report which may help. But that will be complicated task for "just usb" connection software.
Tiktoshi u need to pull up the chip and make it sure with putting it into emmc tool box equipment.
