NAND at GPMC with DMA on AM335x under Linux 3.14/4.1

Hello,

Can you try the prefetch-dma with the latest AM335x SDK:

ti-processor-sdk-linux-am335x-evm-01.00.00.00/board-support/linux-3.14.26-g2489c02

Make sure also you are aligned with the below wiki page:
processors.wiki.ti.com/.../Linux_Core_NAND_User%27s_Guide

See also the below e2e thread:
e2e.ti.com/.../348712

Thanks for the answer. Unfortunately, it has the same behavior as with the other versions.
Do I need to set a special kernel configuration option or one I should not set?

Does the thread e2e.ti.com/.../348712 mean that I have to change the official TI NAND/GPMC driver by myself to get it to work with DMA?

Hello,

Did you use mainline kernel of 4.1.y ?

What is the configuration you chose to compile it ?

Yes, 4.1.y is mainline.
I always used more or less the same configuration, our own.

DMA-Engine is now enabled, I also tested it without.

Hi urs1,

I have downloaded the kernel from https://www.kernel.org/

The latest statble one is 4.1.1

But I am not able to compile it with the above provided configuration.

Can you attach .config file used for 4.1.1 compilation ?

Regards,
Lyf

Hi lyfi,

thanks for testing, I appended the configuration for the Linux 4.1.1 kernel below.

1057.bytepanel_defconfig.tar.gz

Regards

Urs

Do you have solved the DMA problem?

I encounter the same problem.

Unfortunately not, but I did not had time to work on it.
As it is not yet solved, I will do some investigation from time to time.
