I wanted to use 2.8V instead of 3.3V for VCC & VCCQ for Micron's MTFC8GLGDM-AIT Z EMMC v4.41 device. As the datasheet of EMMC card says it is JEDEC/MMC standard version 4.41-compliant, we came to know that 27V is okay.
The signal levels calculated for VCCQ= 2.8V are shown below in red-outlined boxes.
So, I wanted to know the I/O signal levels compatible with imx.6 to check if my 2.8V configuration is practical.
If anyone has previously used such voltage configurations, please do help me solve the issue.
