ARM Cross Compiler: GCC
Download and extract the ARM Cross compiler linaro gcc.
~/
wget -c https://releases.linaro.org/components/toolchain/binaries/5.4-2017.01/arm-linux-gnueabihf/gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf.tar.xz tar xf gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf.tar.xz export CC=`pwd`/gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
Test:

Bootloader: U-Boot
Download :
~/
git clone https://github.com/u-boot/u-boot cd u-boot/ git checkout v2017.03 -b tmp
Patches :
wget -c https://rcn-ee.com/repos/git/u-boot-patches/v2017.03/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch wget -c https://rcn-ee.com/repos/git/u-boot-patches/v2017.03/0002-U-Boot-BeagleBone-Cape-Manager.patch patch -p1 < 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch patch -p1 < 0002-U-Boot-BeagleBone-Cape-Manager.patch
Configure and Build :
~/u-boot
make ARCH=arm CROSS_COMPILE=${CC} distclean
make ARCH=arm CROSS_COMPILE=${CC} am335x_evm_defconfig
make ARCH=arm CROSS_COMPILE=${CC}
Linux Kernel
TI BSP
Download
~/
git clone https://github.com/RobertCNelson/ti-linux-kernel-dev.git cd ti-linux-kernel-dev/
For TI v4.4.x:
~/ti-linux-kernel-dev
git checkout origin/ti-linux-4.4.y -b ti-linux-4.4.y
Update GCC cross compiler path in system.sh
cp system.sh.sample system.sh
Update CC variable with path with GCC compiler path set above
nano system.sh CC=/home/yantrr/gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
Build
~/ti-linux-kernel-dev/
./build_kernel.sh
Update LINUX_GIT variable in system.sh
nano system.sh LINUX_GIT=/home/yantrr/ti-linux-kernel-dev/ignore/linux-src/
Change USB0 Mode :
For VIBE/VIBE2, very first you need to change the USB0 dr_mode from peripheral to host in Beaglebone Black kernel source file KERNEL/arch/arm/boot/dts/am335x-bone-common.dtsi while rebuilding the kernel
&usb0 {
status = "okay";
dr_mode = "host";
};
ZTE and Telit modems driver are already in Beaglebone Black kernel source version 4.4, so no need of any patch for it.
USB Driver configuration for SEW modems:
|
Only needed for SEW modems. |
nano KERNEL/drivers/usb/serial/option.c /* Yantrr Strongrising products */ #define YANTRR_VENDOR_ID 0x21f5 #define YANTRR_PRODUCT_VAYU3GH 0x2012 #define YANTRR_PRODUCT_VAYU3GC 0x2009 #define YANTRR_DONGLE_ID 0x20a6 #define YANTRR_DONGLE_PRODUCT 0x1105
/*Also, add entries in struct usb_device_id option_ids[]*/
{ USB_DEVICE(YANTRR_VENDOR_ID, YANTRR_PRODUCT_VAYU3GH) },
{ USB_DEVICE(YANTRR_VENDOR_ID, YANTRR_PRODUCT_VAYU3GC) },
{ USB_DEVICE(YANTRR_DONGLE_ID, YANTRR_DONGLE_PRODUCT) },
Rebuild Kernel
~/ti-linux-kernel-dev
./tools/rebuild.sh
Check for PPS support under Device Drivers ---> PPS Support
Final output on terminal :
