REG Driving Low a non GPIO pin

Shradhanand Mahendraker

Hi,

The problem iam facing is that i need to configure pins which need to drive low to activate few pins of NAND (which are active low like NAND_WE, NAND_WRITE,NAND_NCS0,NAND_OE) these are to be configure using standard pins not GPIO's.

Can i drive low these pins in some way. if it is GPIO its easier for me and i can do it using the GPIOPinWrite(). But i need to follow my custom schematic. can i do the same for dedicated pins (other than GPIO config in mode 7)?

Regards,

Hi Shradhanand,

You can interface with the NAND using the GPMC of the AM335x SoC. The nand signals like CLE, ALE, CE,CS etc can be controlled using the GPMC interface, as per the NAND timing requirements.

Please refer the StarterWare example for NAND which demonstrates interface with NAND using GPMC on GP EVM board.
