GPMI Documentation

briannorman — Mon, 05 May 2014 20:55:48 GMT

Is there any documentation or reference manual for the GPMI module on the IMX6? I have the iMX6 ref manual, but the GPMI section is lacking any documentation on how to use it. I'm creating a driver in Green Hills and without the linux libraries, the linux drivers are not too helpful. All i need to do is interface existing ONFI board interface calls with the GPMI controller, ie send_cmd, write_page, read_page, etc.

There is no much additional information about the GPMI, nevertheless

the following may be helpful.

Also, please refer to examples in the Platform SDK. Please take a look at

Chapter 13 (Configuring the GPMI Controller) of "iMX6_Firmware_Guide.pdf".

The SDK link :

"Bare-metal SDK for the i.MX 6 series, including reusable drivers and tests for

many peripherals, and much example code. Also includes register definition

headers files, and register definitions for debuggers"

Have a great day,
Yuri

The Platform SDK, linked earlier, contains doc folder.
