Hi,

 

we have an iMX6 custom board running under linux 3.0.35. The board has installed a Spansion 3.3V / 8bit / 512MB nand flash. Linux recognizes the chip and reads the ID (what make us think that all the "pad to pad" connections are right) but is unable to initialize the memory. This is the log:

-----------------------------------------------------------------------------

ONFI flash detected

ONFI param page 0 valid

NAND device: Manufacturer ID: 0x01, Chip ID: 0xdc (AMD S34ML04G1)

failed in set feature of mode : 4

Chip scan failed

gpmi-nand: probe of imx6q-gpmi-nand.0 failed with error -22

GPMI NAND driver registered. (IMX)

-----------------------------------------------------------------------------

 

Any advice?

 

Regards,

Manuel.
