DDR_SDRAM_CFG[ECC_EN] ECC Enable/Disable

DDR_SDRAM_CFG[ECC_EN] ECC Enable/Disable:

Can this register value be enabled/disabled during run time?

Can anyone show insight on this?

Thanks.

Hello Kaurnakar HV

Yes, you can change that. But it's not recommend to do this on-the-fly. Based on experience from our engineer, this could be problematic to guarantee the pipeline of DDR transactions will not cause a read to data with uninitialized ECC.

Have a great day,
Lunmin
