how can user add missing ftdi_sio.ko kernel module #205

Closed dragniko closed 8 years ago

dragniko commented 8 years ago

Is it possible to modify your red-pitaya-notes scripts that build RP image (uname -r returns Linux 4.0.0 Xilinx) by users in order to include "ftdi_sio.ko" module. Or where one can find necessary kernel headers and source files to compile ftdi module directly on RP board? Thanks for your time and effort, Dragan

You can reconfigure and rebuild Linux kernel with the following commands:

cd tmp/linux-xlnx-xilinx-v2015.4
make mrproper
make ARCH=arm xilinx_zynq_defconfig

make ARCH=arm menuconfig

make ARCH=arm CFLAGS="-O2 -mtune=cortex-a9 -mfpu=neon -mfloat-abi=softfp" CROSS_COMPILE=arm-xilinx-linux-gnueabi- UIMAGE_LOADADDR=0x8000 uImage
cp arch/arm/boot/uImage ../../

I've added CONFIG_USB_SERIAL=y and CONFIG_USB_SERIAL_FTDI_SIO=y to linux-xlnx-xilinx-v2015.4.patch. It's currently in the develop branch: https://github.com/pavel-demin/red-pitaya-notes/blob/develop/patches/linux-xlnx-xilinx-v2015.4.patch
