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
NAND Flash Memory : MT29F4G08ABADAWP-ITD(Micron)

Hi 貴博 石川 

simple way to check registers with baremetal obds tests (folder drivers/nand):
