P1010/14 single bit ECC NAND

[renaud]

We are using a P1014 with a SLC NAND using 1-bit ECC. Hence, we do not use the hardware ECC support.

The Linux (v 3.14.0) driver  uses the random input command which is not supported in

the FSL IFC NAND driver.  This leads to an enormous amount of messages and ECC errors reported when using the

ubiformat command. I do not see any support for that command in newer version of Linux

Is there any information that could help me implement the command?

Looking at the other drivers for idea lead me to a silent ubiformat command but did not solve the issue with

ECC errors.

Please open a Service Request to investigate the issue in more detail.

A SR has been opened. I eventually implemented code to support the random data output command.

MTD testing (speedtest, torture, subpage) passed.  The system now boot from NAND.

Thanks to Freescale technical  support.

Please clarify how ECC is calculated in your case.
