TI Keystone Linux Overview¶

Introduction¶

Keystone range of SoCs are based on ARM Cortex-A15 MPCore Processors and c66x DSP cores. This document describes essential information required for users to run Linux on Keystone based EVMs from Texas Instruments.

Following SoCs & EVMs are currently supported:-

K2HK SoC and EVM¶

a.k.a Keystone 2 Hawking/Kepler SoC TCI6636K2H & TCI6636K2K: See documentation at

EVM:: https://www.einfochips.com/index.php/partnerships/texas-instruments/k2e-evm.html

K2L SoC and EVM¶

a.k.a Keystone 2 Lamarr SoC

K2L - TCI6630K2L:

See documentation at: http://www.ti.com/product/TCI6630K2L/technicaldocuments
EVM:: https://www.einfochips.com/index.php/partnerships/texas-instruments/k2l-evm.html

Configuration¶

All of the K2 SoCs/EVMs share a common defconfig, keystone_defconfig and same image is used to boot on individual EVMs. The platform configuration is specified through DTS. Following are the DTS used:

K2HK EVM:
k2hk-evm.dts

K2E EVM:
k2e-evm.dts

K2L EVM:
k2l-evm.dts
