LogicLoader for the OMAP35x Torpedo SOM

Hello,

So, I put the MLO and the lboot.elf file on a SD card and am trying to erase /dev/nand0 from the terminal. However, I keep getting that the area is protected and once I tell 'y' to proceed it comes up with an unknown error -1.

Thank You.

That would be expected if you were booting from NAND.  Here is an example below showing the expected output when booting from NAND memory.

If you find that you are booting from NAND, you might consider format your SD Card with the HP 2.0.6 formatting tool also available on the product website.  This has proven to be more reliable.

You are about to erase one or more protected areas.  This area

I also received the "error: erase: unknown error: -1" error when I didn't enter 'confirm' after having selected 'y' to erase the NAND.



Once I entered 'y' and 'confirm' I was able to successful erase the NAND memory.

The confirm suggestion didn't work. I still get unknown error.

I am trying the HP formatting tool. So, with that I should just format the SD card as FAT32 file system and then put MLO and the .elf files, right?

That is correct.

Have you confirmed that your system was booting from NAND? If you can provide a similar output log with the following commands I can try to determine why you are not able to erase NAND memory.
