Where to get IFT tool?

What processor is this for?  In the OMAP PSP releases there is a tool called signGP for signing the x-loader.

The excerpt from this link discusses how to sign the xloader .bin file.  Depending on which PSP package you are using you will find the signGP in the host-tools directory. 

This is example is from the AM37x and may not apply to your specific board.

Signing x-load.bin

The file x-load.bin needs to be signed before it can be used by the ROM bootloader. The signGP tool required for signing is available in the release package under the folder - host-tools/linux.

To sign the X-Loader binary:

$ signGP x-load.bin

Processor is Omap3530.

What does signing that file actually do?

The boot ROM needs to know where to load the x-loader into internal RAM and how big the image is.  Signing really just adds two words to x-load.bin: An image size and a load address.  Below is a small hexdump of a signed x-load.bin:

00000000  dc 47 00 00 00 08 20 40  12 00 00 ea 14 f0 9f e5  |.G.... @........|
00000010  10 f0 9f e5 0c f0 9f e5  08 f0 9f e5 04 f0 9f e5  |................|
00000020  00 f0 9f e5 04 f0 1f e5  60 09 20 40 78 56 34 12  |........`. @xV4.|

Notice that  the image size is 0x000047dc and the load address is 0x40200800.

This was very helpful.

I have an Om aap4430 Blaze and was wondering the image size and load address for this device. Any help would be appreciated.
