P1021 Large page NAND flashinng using Code warrior.

[safeerkt]

Hello,

We have a custom design based on P1021MDS.In our initial design, we were having a small page flash device which is 512Mb. We have upgraded the NAND device with a large page Micron device which is having 1Gb. We were not able to flash the new NAND before and we have changed some FCM related register in the config file. After this, it started flashing but the boot prints are not coming. It will be really appreciated if someone can share some thoughts on this.

Many Thanks,

Safeer

It is required to check the NAND Flash datasheet section "Error Management" to ensure that the device is supported by the FCM which is capable to correct only 1-bit error in a 512-byte data block.
