There is command available 35to install this image from u-boot. 36 37The port related files can be found at following folders 38 keystone2 SoC related files: arch/arm/cpu/armv7/keystone/ 39 EVMs board files: board/ti/k2s_evm/ 40 41Board configuration files: 42include/configs/k2hk_evm.h 43include/configs/k2e_evm.h 44 45As u-boot is migrating to Kconfig there is also board defconfig files 46configs/k2e_evm_defconfig 47configs/k2hk_evm_defconfig 48 49Supported boot modes: 50 - SPI NOR boot 51 - AEMIF NAND boot 52 53Supported image formats: 54 - u-boot.bin: for loading and running u-boot.bin through Texas instruments 55 code composure studio (CCS) 56 - u-boot-spi.gph: gpimage for programming SPI NOR flash for SPI NOR boot 57 - u-boot-nand.gph: gpimage for programming AEMIF NAND flash for NAND boot 58 59Build instructions: 60=================== 61Examples for k2hk, for k2e just replace k2hk prefix accordingly. 62Don't forget to add ARCH=arm and CROSS_COMPILE. 63 64To build u-boot.bin 65 >make k2hk_evm_defconfig 66 >make u-boot-spi.gph 67 68To build u-boot-spi.gph 69 >make k2hk_evm_defconfig 70 >make u-boot-spi.gph 71 72To build u-boot-nand.gph 73 >make k2hk_evm_defconfig 74 >make u-boot-nand.gph 75 76Load and Run U-Boot on keystone EVMs using CCS 77========================================= 78 79Need Code Composer Studio (CCS) installed on a PC to load and run u-boot.bin 80on EVM. See instructions at below link for installing CCS on a Windows PC. 81http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Getting_Started# 82Installing_Code_Composer_Studio 83Use u-boot.bin from the build folder for loading and running u-boot binary 84on EVM. Follow instructions at 85K2HK http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup 86K2E http://processors.wiki.ti.com/index.php/EVMK2E_Hardware_Setup 87to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode" 88and Power ON the EVM. Follow instructions to connect serial port of EVM to 89PC and start TeraTerm or Hyper Terminal. 90 91Start CCS on a Windows machine and Launch Target 92configuration as instructed at http://processors.wiki.ti.com/index.php/ 93MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS. 94The instructions provided in the above link uses a script for 95loading the u-boot binary on the target EVM. Instead do the following:- 96 971. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D 98 is connected: Unknown)" at the debug window (This is created once Target 99 configuration is launched) and select "Connect Target". 1002. Once target connect is successful, choose Tools->Load Memory option from the 101 top level menu. At the Load Memory window, choose the file u-boot.bin 102 through "Browse" button and click "next >" button. In the next window, enter 103 Start address as 0xc001000, choose Type-size "32 bits" and click "Finish" 104 button. 1053. Click View -> Registers from the top level menu to view registers window. 1064. From Registers, window expand "Core Registers" to view PC. Edit PC value 107 to be 0xc001000. From the "Run" top level menu, select "Free Run" 1085. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as 109 below and type any key to stop autoboot as instructed := 110 111U-Boot 2014.04-rc1-00201-gc215b5a (Mar 21 2014 - 12:47:59) 112 113I2C: ready 114Detected SO-DIMM [SQR-SD3T-2G1333SED] 115DRAM: 1.1 GiB 116NAND: 512 MiB 117Net: K2HK_EMAC 118Warning: K2HK_EMAC using MAC address from net device 119, K2HK_EMAC1, K2HK_EMAC2, K2HK_EMAC3 120Hit any key to stop autoboot: 0 121 122SPI NOR Flash programming instructions 123====================================== 124U-Boot image can be flashed to first 512KB of the NOR flash using following 125instructions: 126 1271. Start CCS and run U-boot as described above. 1282. Suspend Target. Select Run -> Suspend from top level menu 129 CortexA15_1 (Free Running)" 1303. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000 131 through CCS as described in step 2 of "Load and Run U-Boot on K2HK/K2E EVM 132 using CCS", but using address 0x87000000. 1334. Free Run the target as described earlier (step 4) to get u-boot prompt 1345. At the U-Boot console type following to setup u-boot environment variables. 135 setenv addr_uboot 0x87000000 136 setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000> 137 run burn_uboot_spi 138 Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 139 to "SPI Little Endian Boot mode" as per instruction at 140 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1416. Power ON the EVM. The EVM now boots with u-boot image on the NOR flash. 142 143AEMIF NAND Flash programming instructions 144====================================== 145U-Boot image can be flashed to first 1024KB of the NAND flash using following 146instructions: 147 1481. Start CCS and run U-boot as described above. 1492. Suspend Target. Select Run -> Suspend from top level menu 150 CortexA15_1 (Free Running)" 1513. Load u-boot-nand.gph binary from build folder on to DDR address 0x87000000 152 through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM 153 using CCS", but using address 0x87000000. 1544. Free Run the target as described earlier (step 4) to get u-boot prompt 1555. At the U-Boot console type following to setup u-boot environment variables. 156 setenv filesize <size in hex of u-boot-nand.gph rounded to hex 0x10000> 157 run burn_uboot_nand 158 Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 159 to "ARM NAND Boot mode" as per instruction at 160 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1616. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash. 162
