Other Parts Discussed in Thread: DM3730

I've downloaded OMAPPSP_04.02.00.07 xloader.

What configuration should I choose for compiling xloader for dm3730?

Does the this xloader support booting from ROM flash?

Thanks,

Hi Tal,

You should choose omap3evm_config for compiling x-loader for DM3730.

You could read more details in the AM35x-OMAP35x-PSP 04.02.00.07 UserGuide at the following link:

Hi

Thanks allot for your reply.
What about NOR flash? Does the omap3evm_config support running the xloader from NOR flash?
I saw there is some support for NOR flash when using omap3evm_config but don't yet understand the xloader code completely to answer that.
I've got another question after reading the link you've send regarding the xloader. It says there that the xloader should be signed.
Is it mandatory?
Does it change the binary itself?
It says that the after signing "x-load.bin.ift" is created. Should it be used somehow?

Thanks again,
Tal

You should not need an x-loader to boot from NOR. NOR is XIP so the boot ROM will configure GPMC and then jump to address 0x08000000 (the beginning of the NOR flash). If your u-boot supports NOR boot that's what should be flashed. I have not looked at NOR in a while so I'm not sure if u-boot supports it for omap3evm.

OK. Thanks.

What about the xloader signing. Is it essential?

Best regards,

The signing process is essential to make xloader completed. Signing process adding some security keys to the xloader which allow the processor to decrypt and execute it.
