1. In the Table 8-10 of i.MX6ULL reference manual <http://nxp.com/doc/imx6ullrm>, BOOT_CFG2[4:3] for boot search count. Are 00, 01 both for two boot search count?

2. In the Table 5-7 of i.MX6ULL reference manual <http://nxp.com/doc/imx6ullrm>, there are some reserved pins for NAND boot, like BOOT_CFG2[0]. What is the recommended status for these reserved pins when booting? NC, pull-up, pull-down?

Hello,

 

1.- Yes, you're a correct

2.- You may place a pull-down resistor to this reserved pins, if planning to use fuses please do not burn these, as the behavior may be unpredictable.

 

Hope this helps,

Best regards,

Aldo.
