U-Boot port for Texas Instruments XTCIEVMK2X
|
|
============================================
|
|
|
|
Author: Murali Karicheri <m-karicheri2@ti.com>
|
|
|
|
This README has information on the u-boot port for XTCIEVMK2X EVM board.
|
|
Documentation for this board can be found at
|
|
http://www.advantech.com/Support/TI-EVM/EVMK2HX_sd.aspx
|
|
|
|
The board is based on Texas Instruments Keystone2 family of SoCs : K2H, K2K.
|
|
More details on these SoCs are available at company websites
|
|
K2K: http://www.ti.com/product/tci6638k2k
|
|
K2H: http://www.ti.com/product/tci6638k2h
|
|
|
|
Board configuration:
|
|
====================
|
|
|
|
Some of the peripherals that are configured by u-boot are:-
|
|
|
|
1. 2GB DDR3 (can support 8GB SO DIMM as well)
|
|
2. 512M NAND (over ti emif16 bus)
|
|
3. 6MB MSM SRAM (part of the SoC)
|
|
4. two 1GBit Ethernet ports (SoC supports upto 4)
|
|
5. two UART ports
|
|
6. three i2c interfaces
|
|
7. three spi interfaces (only 1 interface supported in driver)
|
|
|
|
There are seperate PLLs to drive clocks to Tetris ARM and Peripherals.
|
|
To bring up SMP Linux on this board, there is a boot monitor
|
|
code that will be installed in MSMC SRAM. There is command available
|
|
to install this image from u-boot.
|
|
|
|
The port related files can be found at following folders
|
|
keystone2 SoC related files: arch/arm/cpu/armv7/keystone/

Load and Run U-Boot on K2HK EVM using CCS
|
|
=========================================
|
|
|
|
Need Code Composer Studio (CCS) installed on a PC to load and run u-boot.bin
|
|
on EVM. See instructions at below link for installing CCS on a Windows PC.
|
|
http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Getting_Started#
|
|
Installing_Code_Composer_Studio
|
|
Use u-boot.bin from the build folder for loading annd running u-boot binary
|
|
on EVM. Follow instructions at
|
|
http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup
|
|
to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode"
|
|
and Power ON the EVM. Follow instructions to connect serial port of EVM to
|
|
PC and start TeraTerm or Hyper Terminal.
|
|
|
|
Start CCS on a Windows machine and Launch Target
|
|
configuration as instructed at http://processors.wiki.ti.com/index.php/
|
|
MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS.
|
|
The instructions provided in the above link uses a script for
|
|
loading the u-boot binary on the target EVM. Instead do the following:-
|
|
|
|
1. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D
|
|
isconnected: Unknown)" at the debug window (This is created once Target
|
|
configuration is launched) and select "Connect Target".
|
|
2. Once target connect is successful, choose Tools->Load Memory option from the
|
|
top level menu. At the Load Memory window, choose the file u-boot.bin
|
|
through "Browse" button and click "next >" button. In the next window, enter
|
|
Start address as 0xc001000, choose Type-size "32 bits" and click "Finish"
|
|
button.
|
|
3. Click View -> Registers from the top level menu to view registers window.
|
|
4. From Registers, window expand "Core Registers" to view PC. Edit PC value
|
|
to be 0xc001000. From the "Run" top level menu, select "Free Run"
|
|
5. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as
|
|
below and type any key to stop autoboot as instructed :=

SPI NOR Flash programming instructions
|
|
======================================
|
|
U-Boot image can be flashed to first 512KB of the NOR flash using following
|
|
instructions:-
|
|
|
|
1. Start CCS and run U-boot as described above.
|
|
2. Suspend Target. Select Run -> Suspend from top level menu
|
|
CortexA15_1 (Free Running)"
|
|
3. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000
|
|
through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
|
|
using CCS", but using address 0x87000000.
|
|
4. Free Run the target as desribed earlier (step 4) to get u-boot prompt
|
|
5. At the U-Boot console type following to setup u-boot environment variables.
|
|
setenv addr_uboot 0x87000000
|
|
setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000>
|
|
run burn_uboot_spi
|
|
Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
|
|
to "SPI Little Endian Boot mode" as per instruction at
|
|
http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup.
|
|
6. Power ON the EVM. The EVM now boots with u-boot image on the NOR flash.
|
|
|
|
AEMIF NAND Flash programming instructions
|
|
======================================
|
|
U-Boot image can be flashed to first 1024KB of the NAND flash using following
|
|
instructions:-
|
|
|
|
1. Start CCS and run U-boot as described above.
|
|
2. Suspend Target. Select Run -> Suspend from top level menu
|
|
CortexA15_1 (Free Running)"
|
|
3. Load u-boot-nand.gph binary from build folder on to DDR address 0x87000000
|
|
through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
|
|
using CCS", but using address 0x87000000.
|
|
4. Free Run the target as desribed earlier (step 4) to get u-boot prompt
|
|
5. At the U-Boot console type following to setup u-boot environment variables.
|
|
setenv filesize <size in hex of u-boot-nand.gph rounded to hex 0x10000>
|
|
run burn_uboot_nand
|
|
Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
|
|
to "ARM NAND Boot mode" as per instruction at
|
|
http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup.
|
|
6. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash.
