Part Number: TMS320DM8168
Hi,
I was going through the EVM of DM8168 and has a doubt regarding NAND booting. Please clarify it.
As per the datasheet to select NAND booting, setting BTMODE[3:0] is enough, which can be set via SW3 on EVM. But in EVM SW4 is also used to select NAND booting.
Actually, in EVM based on SW4(active low) input, AH7 pin of dm8168 is connected to the 9th pin /CE of NAND Flash via a 74CBTLV1G125CR (Lo-Vltg Single FET Bus Sw).
My doubt is if i can connect AH7 pin of dm8168 is to the 9th pin /CE of NAND and then by setting BTMODE[3:0] i can select NAND booting. In this way i can remove 74CBTLV1G125CR.
Actually i am not understanding the necessity of 74CBTLV1G125CR.
Please help me out with this..
Regards,
Shyama
