Nancy Wang

Part Number: AM5728

Hi,

There is a SDRAM on TMDXIDK57X used as DDRECC, must it be used? What is the purpose? Is there any information for reference?

Hello Nancy,

Yes there is some more information available on the TRM Section 15.3.4.14.

The purpose for ECC on memory is protect against data corruption by automatically detecting and correcting errors.

I doesn't have to be used, one could enable/disable ECC via EMIF_ECC_CTRL_REG.

Please see the errata document for its use in AM572x devices.
