I am using iMX6UL in one of my custom board design and interfaced µSD card to uSDHC2 port on iMX6UL LCD port pins. I have not used LCD in my design. LCD port is used as uSDHC2 port here.
I am not able to boot from µSD card though all boot config resistor and boot mode setting resistors are correctly loaded on board.
By referring paragraph in iMX6UL reference manual page # 273, SD card can be connected to any uSDHC port and can be booted by copying 4Kbyte of data from SD card to internal RAM.
So can i boot from uSDHC2 port on LCD port pins.?
