Hi Chanchal,

Which TI device do you use? Which Linux kernel version do you use?

Hi,

My Linux kernel version is 4.15.0-162-generic and TI device is AM3359 processor. Basically I want to transfer the data by using GPMC interface from AM3359 Sitara Processor to FPGA using NAND Flash. Please help me in providing GPMC code with all dependency files of Linux kernel and driver which will be required for transferring data from Processor to FPGA and compilation steps for generating .ko file.

Thanks

Hi Chanchal,

It seems the kernel version you use is not provided by TI.
The GPMC and NAND drivers are already included in the Processor SDK kernel, please refer to the AM335x GPEVM devicetree and kernel defconfig tisdk_am335x-evm_defconfig for details.
