Part Number: AM5728

Hi,

Customer want to connect 8 nand flash by GPMC. But GPMC_CS4 pinmux with gpmc_ben0, can we use gpio simulate chip selection signal?

Hi,

We don't think it would be possible to simulate CS with GPIO.

Is it 8 NAND flash or 8-bit NAND flash?

Hi,

There are 8 nand flash. So he needs eight chip select signals. He want to use GPIO to achieve chip selection due to pin conflict.

Hi,

We don't have support in software for GPIO based CS and also we have not tested or tried more than one NAND devices.
