SDRAM ECC

Hello teams.

We designed an i.MX RT1171 custom board and connect it to the SDRAM on the SEMC bus.
Please tell us how to enable ECC.

We enabled XECC_SEMC[ECC_CTRL] bit2-0 and address settings, but it doesn't work.
Must be set to the eFUSE 0x840[3] bit?
Is there any other settings ?

Best regards.

eFUSE 0x840[3] bit should be burnt to enable XECC module, or XECC is inactive by default.

See my blog for XECC enablement.
