ARM Cross Compiler: GCC

This is a pre-built (64bit) version of Linaro GCC that runs on generic linux, sorry (32bit) x86 users, it's time to upgrade...

TI BSP

WARNING: do not use if you are not use to re-basing git branches, as this is based onhttp://git.ti.com/gitweb/?p=ti-linux-kernel/ti-linux-kernel.git;a=shortlog;h=refs/heads/ti-linux-4.1.y
instead of a stable kernel branch. Thus you will have to do: (git checkout master -f ; git branch -D tmp ; git pull ; git checkout origin/ti-linux-4.1.y -b tmp) often..

Setup microSD card

For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.

Erase partition table/labels on microSD card:

Install Bootloader:

~/

Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.

sfdisk

sfdisk >= 2.26.x

sfdisk <= 2.25.x

Format Partition:
With mkfs.ext4 1.43, we need to make sure metadata_csum and 64bit are disabled, as U-Boot CAN NOT currently handle these newer ext4 options.

mkfs.ext4 -V

mkfs.ext4 >= 1.43

mkfs.ext4 <= 1.42

Mount Partition:
On most systems these partitions may will be auto-mounted...

Backup Bootloader

This version of MLO/u-boot.img will be used on the "eMMC" flasher script on this page.

~/

Dealing with old Bootloader in eMMC

If you don't want to clear out the old Bootloader in eMMC add this uEnv.txt to /media/rootfs/

~/uEnv.txt

~/

Install Kernel and Root File System

To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.

Copy and paste that "export kernel_version=4.X.Y-Z" exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.

Temp Script:

HDMI

This sections assumes you have already installed your favorite xorg based window manager, such as lxde, xfce, kde, gnome, etc... These are packages that need to be installed on top of your selected windows manager and an xorg.conf needed to correctly setup
the video interface.
Note: If the cursor doesn\'t show up right away, first hit: ctlr-alt-f1 then: ctrl-alt-f7 after which it \'should\' show up...

Make sure to install, modesetting driver and xrandr utilities:

/etc/X11/xorg.conf

xrandr:

xrandr (over serial/ssh)

eMMC

Script to copy your microSD card to eMMC: (this will need these packages installed: initramfs-tools dosfstools rsync)

SGX

Build SGX modules/userspace (must be done on an x86, due to the TI 5.01.01.02 blob extractor)
