DaVinci PSP 03.22.00.06 NOR Driver

Other Parts Discussed in Thread: OMAPL138

Hi,

we are working about "DaVinci PSP 03.22.00.06", in the document "DaVinci PSP 03.22.00.06 Device Driver Features and Performance Guide" in the chapter "NAND flash driver architecture" you describe the driver about hardware interface : Async EMIF. In the chapter "NOR flash driver architecture" you describe the driver but not hardware interface . Can you confirm that NOR flash driver works with Async EMIF hardware interface ?

Hi,
We can also interface NOR flash through EMIFA interface.

Yes, the OMAPL138 can connect NOR flash through EMIFA interface , I agree.

But "DaVinci PSP 03.22.00.06 Device Driver" for NOR Flash use EMIFA interface or for example SPI interface ?

Sergio.

Hi,
OMAPL138 EVM board has parallel NOR flash not serial NOR (SPI) so we have to enable the EMIFA NOR driver.
