Hi NXP,

 

We use one NAND flash memory.
Please teach us the recommended register value of the GPMI.
Please refer to the following register item.

 

The NAND flash memory is MT29F4G08ABADAWP-ITD(Micron).
After setting register value, we will measure and inspect control signals.
If necessary, we adjust the register value.

 

Best Regards,

 

Processor : MCIMX283DVM4B
