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,
