Keystone SPI boot - Parameter Table Index

David Meixner
Expert 4010 points

The SPI boot mode for Keystone devices has a bit field "Paramter Table Index" with valid values of 0-3 (table 3-29 of SPRUGY5B).

Where are these 4 parameter tables defined and/or what should this value be set to?

Thanks,
David

    David,

    The MCSDK has the tiboot.h under \mcsdk_2_01_02_05\tools\boot_loader\ibl\src\device. This has all the boot parameter table for all the boot modes for different devices.

    Thanks,

    Arun.

    Hi Arun, I took a look at the source code, and I'm still unclear how the boot pins affect the SPI boot parameter table. Specifically, what does boot[0-3] "Paramter Table Index" relate to? I couldn't find anywhere in the code where the boot pins are read.

    Possibly, does this directly translate to Options in the SPI boot parameter table?

    Thanks,
    David
