Hello,

      I'm trying to biuld a uboot to detect the DDR data error on my B4860QDS board.And from the datasheet I learn that the ERR_DETEC,ERR_DISABLE,ERR_INT_EN registers that I can read them to get the error informaition.So I short-circuit two data signals of DDR to the ground deliberately,but the board can startup properly without generating a interrupt or set other error flags.I wonder if it is possible to get these DDR data error information and how to realize this in uboot?Furthermore ,it is possible to get DDR address error information?

 

Thanks.
