Hi all;
I tried by changing the omap3 board file,for nand at chip select 7,
arch/arm/mach-omap2/board-omap3beagle.c file:
modified chip select 0 to chip select 7!!!!!!!!
when i'm booting , below error i got?
How to come out of this error , anyone did configuration in kernel to access the nand at chip select 7, other than the chip select 0 (which is default)
omap2-nand driver initializing
