I am currently using vivado 14.2. My final target is to access memory mapped device in Programmable Logic from Linaro. I have cloned
u-boot(2014_R2),kernel(2014_R2) & hardware design(2014_R2), which are compitable with vivado 14.2. I want to use axi_dma but kernel version
2014_R2 doesn't have axi_dma drivers. In kernel version 2015_R1, axi_dma drivers are available.
I copied the axi_dma driver from kernel@2015_R1 in kernel@2014_R2 & built kernel@2014_R2, but kernel becomes panic at the booting time
I am new in kernel device drivers.Do you please help me to know how can I integrate axi_dma driver in kernel@2014_R2.
Thanks & Regards,
