Problem with NAND flash!!!

Other Parts Discussed in Thread: OMAP3530

          Hello,

I was following the OMAP 3530 Software Development Guide. I created an SD card image and then i tried to do this :

 

How to copy boot loaders to NAND flash
This section explains the procedure required for copying boot loaders (x-loader and u-boot) on NAND flash.
The steps assumes that you have a working SD card image.
1. Boot the OMAP3530 EVM with SD card. See #How to create an SD card
2. Halt the u-boot auto boot process and enter the following commands to copy x-loader (i.e MLO) and
u-boot from SD card to NAND flash.

nand erase 0 20000
nand erase 80000 40000
nandecc hw
mmc init
fatload mmc 0 0x81600000 MLO       at this point I made a syntax mistake and than everything FAIL. Now i can't connect to Beagle Board!
nand write.i 0x81600000 0 20000
nandecc sw
fatload mmc 0 0x81600000 u-boot.bin
nand write.i 0x81600000 80000 40000

3. Power OFF the EVM and remove the SD card.
4. Set the SW4 switch to boot from NAND (1 = "On" position on the switch):
SW4 = 00101010 (high to low, i.e. SW4.1 = 0)
5. Power ON the EVM.
What can I do now? I will be would be grateful if somebody Help me, because I have to made a diploma thesis.

    Your MMC/SD boot mode should be still working fine, you can again reboot the system through MMC/SD boot and follow above steps again. If SD card got corrupted (which is unlikely) you may want to try formatting the card, restore the images and try booting again.

    Thanks,

    I must configure minicom again or something with Beagle Board is not right ? Thanks in advance...
