AM2431: I don't know how to handle an address error in TRM "8.1.4.4 Address Alias ​​Prevention"

Hi 

I am looking at your query. Please expect reply in a day or two.

The DDR wrapper has the SDRAM_IDX and REGION_IDX parameters to describe the physical size of the DDR on the board.  This helps the wrapper determine if an out of range address is trying to be accessed, and can flag it in the AERR bit interrupt register

For example, if you have a 2GByte DDR on the board, the SDRAM_IDX=0xF and REGION_IDX=0xF (ie, the V2A_CTL_REG = 0x1EF).  The DDR register configuration tool https://dev.ti.com/sysconfig/?product=Processor_DDR_Config&device=AM64x has parameters to set these appropriately based on your system settings.
