Am designing i.MX UL processor based board. The media is NAND Flash.
There are 24 Boot Configuration Pins(BOOT_CFG1[7:0],BOOT_CFG2[7:0],BOOT_CFG3[7:0]). I found only the status of BOOT_CFG1[7:0] for NAND Boot.
Please let me know the what should be the status(Pull up/Pull down) of BOOT_CFG2[7:0],BOOT_CFG3[7:0] during board boot.
