Original question:

TMS320C6657: IBL programming instruction

TMS320C6657: NOR booting with IBL

Part Number: TMS320C6657

I am trying to load and boot my own code from the NOR flash. From the PSDK document, I come across the following.

Just want to confirm on the regions in the L2 memory that my custom app can not use when it is loaded by the IBL.

By the way, where can I find the source code of the demos that are loaded on the 6657EVM?

Thanks.

    I think I found the source code for the POST demo in the PSDK. From the map file of the demo, it looks like it left out the first 0x30000 of the L2 memory and that was it.
