Dont need vcc, vccq, simple usb cable connected to the board is enough. (Because it's qc cpu)

Sorry to say but it seems something wrong whit this pinout because Scan EMMC works now, but other operations not, and also tp finder finds D0 almost every resistor around CPU i connect...

this pinout is correct, removed the chip, and checked with multimeter, everything is the right place, i checked the EMMC after reball in EMMC socket and working fine, so i think cpu is makes some trouble between the communication of ATF <=> EMMC. Maybe... But the pinout is right.
