iMX 8M mini processor

[pantarun_92]

Hi, 

In our design if we are not using a NOR flash like done in EVK board for iMX 8M mini, what to do with the NAND interface PINS used for FLASH connectivity?

Shall we leave them unconnected, no such guide is present in IMX8MMHDG,please recommend usage

Also, CLKIN1, CLKIN2, CLKOUT1, CLKOUT2, is there any clock signal available there, what is the frequency, can we use it to clock some other peripheral device?

Standalone SOM board can support eMMC/SDHC3 boot, by populating R71, R72, R75, R76, R79, R95, R97! Can this be used to boot from eMMC directly without setting the boot switches SW1101 & SW1102 or without the baseboard, any documentation on this

Please write back,

thanks,

Arun

they can be left unconnected.

> CLKIN1, CLKIN2, CLKOUT1, CLKOUT2, is there any clock signal available there

these clocks are programmable, description can be found in sect.5.1.8.38 PLL Clock Output for Test Enable and Select Register (CCM_ANALOG_ANAMIX_PLL_MNIT_CTL)

i.MX 8M Mini Applications Processor Reference Manual

>Can this be used to boot from eMMC directly without setting the boot switches SW1101 & SW1102 

not sorry.
