See instructions at below link for installing CCS on a Windows PC. 89http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Getting_Started# 90Installing_Code_Composer_Studio 91Use u-boot.bin from the build folder for loading and running u-boot binary 92on EVM. Follow instructions at 93K2HK http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup 94K2E http://processors.wiki.ti.com/index.php/EVMK2E_Hardware_Setup 95K2L http://processors.wiki.ti.com/index.php/TCIEVMK2L_Hardware_Setup 96 97to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode" 98and Power ON the EVM. Follow instructions to connect serial port of EVM to 99PC and start TeraTerm or Hyper Terminal. 100 101Start CCS on a Windows machine and Launch Target 102configuration as instructed at http://processors.wiki.ti.com/index.php/ 103MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS. 104The instructions provided in the above link uses a script for 105loading the u-boot binary on the target EVM. Instead do the following:- 106 1071. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D 108 is connected: Unknown)" at the debug window (This is created once Target 109 configuration is launched) and select "Connect Target". 1102. Once target connect is successful, choose Tools->Load Memory option from the 111 top level menu. At the Load Memory window, choose the file u-boot.bin 112 through "Browse" button and click "next >" button. In the next window, enter 113 Start address as 0xc001000, choose Type-size "32 bits" and click "Finish" 114 button. 1153. Click View -> Registers from the top level menu to view registers window. 1164. From Registers, window expand "Core Registers" to view PC. Edit PC value 117 to be 0xc001000. From the "Run" top level menu, select "Free Run" 1185. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as 119 below and type any key to stop autoboot as instructed := 120 121U-Boot 2014.04-rc1-00201-gc215b5a (Mar 21 2014 - 12:47:59) 122 123I2C: ready 124Detected SO-DIMM [SQR-SD3T-2G1333SED] 125DRAM: 1.1 GiB 126NAND: 512 MiB 127Net: K2HK_EMAC 128Warning: K2HK_EMAC using MAC address from net device 129, K2HK_EMAC1, K2HK_EMAC2, K2HK_EMAC3 130Hit any key to stop autoboot: 0 131 132SPI NOR Flash programming instructions 133====================================== 134U-Boot image can be flashed to first 512KB of the NOR flash using following 135instructions: 136 1371. Start CCS and run U-boot as described above. 1382. Suspend Target. Select Run -> Suspend from top level menu 139 CortexA15_1 (Free Running)" 1403. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000 141 through CCS as described in step 2 of "Load and Run U-Boot on K2HK/K2E/K2L 142 EVM using CCS", but using address 0x87000000. 1434. Free Run the target as described earlier (step 4) to get u-boot prompt 1445. At the U-Boot console type following to setup u-boot environment variables. 145 setenv addr_uboot 0x87000000 146 setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000> 147 run burn_uboot_spi 148 Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 149 to "SPI Little Endian Boot mode" as per instruction at 150 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1516. Power ON the EVM. The EVM now boots with u-boot image on the NOR flash. 152 153AEMIF NAND Flash programming instructions 154====================================== 155U-Boot image can be flashed to first 1024KB of the NAND flash using following 156instructions: 157 1581. Start CCS and run U-boot as described above. 1592. Suspend Target. Select Run -> Suspend from top level menu 160 CortexA15_1 (Free Running)" 1613. Load u-boot-nand.gph binary from build folder on to DDR address 0x87000000 162 through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM 163 using CCS", but using address 0x87000000. 1644. Free Run the target as described earlier (step 4) to get u-boot prompt 1655. At the U-Boot console type following to setup u-boot environment variables. 166 setenv filesize <size in hex of u-boot-nand.gph rounded to hex 0x10000> 167 run burn_uboot_nand 168 Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 169 to "ARM NAND Boot mode" as per instruction at 170 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1716. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash. 172
