Does P5040 support MLC nandflash?BTW,if support ,8 bit or 24 bit ECC?

Question as my topic.

For ECC generation please look P5040 Reference Manual, Section 13.4.3.1.3 "Error correcting codes and the spare region"

P5040 has the older eLBC NAND controller, which only supports 1-bit hardware ECC, so MLC is not supported unless you use software ECC or on-die ECC (either of which would require some driver modifications to work, and would not provide ECC protection when booting firmware from NAND).  Our T-series chips (e.g. T1040, T2080, T4240) have the IFC NAND controller which supports 4, 8, 24, and 40-bit hardware ECC.

Hi Wood ,

Got it ,thanks a lot.

Also be aware that (unlike IFC) eLBC only supports page sizes of 512 or 2048 bytes.
