We are replacing the NAND flash on our custom board from feature set 'D' to 'B' is the ti8148 nand driver compatible with this feature set ?
Thanks And Regards,
Mike

Hi Pavel,
Yes I am planning to boot from NAND and also have the UBIFS file system into it.
Regarding feature set it can be found at [1] earlier it was 4Gb with feature set D
and now we are planning to use 8Gb with feature set B (MT29F8G08ABABAWP-ITX:B).
The links which you shared dont talk about feature sets.
Any pointers on

Thanks And Regards,

Then your NAND flash chip should be compatible with the DM814x ROM code, see DM814x TRM, section 4.7.3 NAND

Up to 64Gb (64Gbit/8GByte) capacity is supported by the ROM Code, so this 4Gb to 8Gb update should not be a problem.

Yes because feature set is not the important thing here, the important things are capacity, ONFI support, device ID, bus width, page size, etc.

The latest linux kernel supports BCH16:
