Relationship between LS1024A CS2 and NAND FLASH(MT29F16G08CBACAWP)

h201668 — Wed, 14 Sep 2022 23:04:00 GMT

This time I am a beginner using NXP for the first time.

I am using LS1024A for the first time

Similar to LS1024ARDG, the circuit is configured and used.

When NAND Flash (MT29F16G08CBACAWP) is used with CS2, an ECC error occurs in NAND flash.

Nand flash is normal when not using CS2.

It is necessary to check whether there is a pin that controls CS2 and whether CS2 and nand flash are related.

In the first picture, the nand cs signal is partially abnormal.

If cs2 is used, the nand cs signal is strange in picture 1.

If cs2 is not used, the nand cs signal comes out normally.

In the LS1024A, CS2 and NAND flash have nothing to do with each other, which is more confusing.

Please refer to the photo below.

I need a lot of help.

1.CS2 with NAND flash ECC error signal

2.NAND flash signal without cs2
