Hi, I have several eMMC KLMAG1JETD chips, and they are all readable, but one chip behaves strangely!
The error looks like this :

Init EMMC... OK!    ( ( OR register: C0FF8080 )
Reading ECSD : Succeeded
Authentication Key not yet programmed, RPM not used
Switch to USER AREA Error!
The EMMC version is lower, Testing  frequency <= 20MHZ

I exclude bad contact, the programmer sees the flash memory, but cannot read it.

Please help me!
