i.mx8MM ddr4 board nand flash size change ?

[weikeng-jimmy]

Hi Sir,

            I write NAND boot image into NAND flash (64G) and switch the mode to NAND boot , the Imx8mm EVK can boot up successful.  I will change NAND flash size from 64G (MT29F64G08CBABBWP) to 8G (MT29F8G08ABACA) , it's not boot up.  I try to switch the "pages in block to 01-64" , but it's still not boot up .

Did I lose any steps or moves?

Hi @weikeng-jimmy!

I'm having the same issue you had with your NAND flash. I'm also using an 8Gbit NAND and I couldn't boot the i.MX8MM using it yet.

What is the patch you had to use to fix the problem? Could you help me with that? 

Thanks!
