Hi All,

I am referring datasheet of DM814x (SPRS647B).

InTable 4-2. XIP (on GPMC) Boot Options there are two terms used (M0) & (M1) in the first column.

Can anyone pls clarify  the meaning of these.

 

Thanks in advance.

    Would be nice to have some explanation of M0 and M1.

    Datasheet do not tell anything.

    Table 4-2 is not clear how to read this option M0, M1. Would be nice to know which DSP pins should be use with option M0 and which with option M1?

      

    Address assignment */GPMC_A[1:12]/* (M0) / */GPMC_A[1:12]/* (M1)

     

    For example: what should be done to use pins T23, H26……….., and when pins J28, K27, M24 can be used?

    I like to use pins T23-GPMC_A[1], H26-GPMC_A[2]……… what should be done to boot the DSP using this pins assignment?  

    What is the meaning of the DEFAULT in this table?
