Hi Champs:

We cannot find any documents / codes related to the GPMC for AM64/65.

May someone help us?

THanks.

Hi Rio,

The device TRM has a chapter for GPMC.

Linux has kernel driver for GPMC.

Hi Bin:

I try to grep any GPMC keyword in the kernel, but I cannot find any clue.

May you point out the path?

BTW, do we have the wiki/ document to address how to test the GPMC and performance?

THAnks.

Some questions:

#1. the k3 dts has no mentioning regarding the AM64/65 GPMC pinmux.

#2. is the drvier/memory/omap-gpmc.c the one as your saying?

Hi Rio,

Sorry for my misleading information in my first response above.

I just learned that GPMC is not currently supported in Linux for any K3 device, including AM65x and AM64x.
