Hello all !!!
I have Some issues while formatting my SD Card that too with only one partition, of type vfat...I hope u can help me in this case..
I have used below shown script to format my SD Card..On Executing this script it works fine.It will format the SD Card with One partition of
type vfat...After that i copied all my binary images such as MLO u-boot.bin boot.scr to that partition..
The problem occurs when i try to boot up the omap4 based board, in my console i was able to see some graphical characters printing..
I changed my UART then i tried ,then also i was able to see the same... I doubts in my code ....Can u help in resolving this...
