Hi,
I follow the instructions in the PCIe root complex design 2014.2 on the mini-ITX board in order to build the Linux kernel. But I have two problems now.
First, I download the kernel from
git://github.com/Xilinx/linux-xlnx.git
I check the kernel version and it is 3.14
After i have applied the patch,
git am zynq_rc_nwl_drivers.patch
the kernel version is changed to 3.9,
so is it a correct result that the kernel version changes?
Second, since i want to use this PCIe RC design to control a solid state disk, i add the SATA and ACHI drivers in the menuconfig as follows,
make ARCH=arm zc706_rc_defconfig
make ARCH=arm menuconfig
after i have added the SATA drviers, I build the kernel by
make ARCH=arm uImage -j 4 UIMAGE_LOADADDR=0x8000
However, a lot of options jump out as follows:
hadoop@cubiemaster:~/kernel/linux-xlnx$ git apply --check zynq_rc_nwl_drivers.patch
hadoop@cubiemaster:~/kernel/linux-xlnx$ git am zynq_rc_nwl_drivers.patch

It seems that it is not config properly...
I don't know if i have made any operations incorrectly?
Any suggestions will be appreciated!
Thank You!
