Part Number: TMS320C6657
We are currently seeing some issues where there is "bit rot" of the intermediate bootloader (IBL) programmed into a NAND flash device attached to the DSP. From the KeyStone Architecture DSP Bootloader User Guide section 3.11 it seems to imply that the RBL should be doing some ECC but we are not seeing that.
In our investigation (pulling the data from the NAND device) we see that one bit has been flipped (corrupted) in the intermediate bootloder image residing in teh NAND device. This one bit corruption prevents the IBL from running and our sytem from booting.
So the question is, "does the RBL strapped to NAND boot actually run ECC?"
