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-dtb.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 87K2L http://processors.wiki.ti.com/index.php/TCIEVMK2L_Hardware_Setup 88 89to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode" 90and Power ON the EVM. Follow instructions to connect serial port of EVM to 91PC and start TeraTerm or Hyper Terminal. 92 93Start CCS on a Windows machine and Launch Target 94configuration as instructed at http://processors.wiki.ti.com/index.php/ 95MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS. 96The instructions provided in the above link uses a script for 97loading the U-Boot binary on the target EVM. Instead do the following:- 98 991. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D 100 is connected: Unknown)" at the debug window (This is created once Target 101 configuration is launched) and select "Connect Target". 1022. Once target connect is successful, choose Tools->Load Memory option from the 103 top level menu. At the Load Memory window, choose the file u-boot-dtb.bin 104 through "Browse" button and click "next >" button. In the next window, enter 105 Start address as 0xc001000, choose Type-size "32 bits" and click "Finish" 106 button. 1073. Click View -> Registers from the top level menu to view registers window. 1084. From Registers, window expand "Core Registers" to view PC. Edit PC value 109 to be 0xc001000. From the "Run" top level menu, select "Free Run" 1105. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as 111 below and type any key to stop autoboot as instructed := 112 113U-Boot 2014.04-rc1-00201-gc215b5a (Mar 21 2014 - 12:47:59) 114 115I2C: ready 116Detected SO-DIMM [SQR-SD3T-2G1333SED] 117DRAM: 1.1 GiB 118NAND: 512 MiB 119Net: K2HK_EMAC 120Warning: K2HK_EMAC using MAC address from net device 121, K2HK_EMAC1, K2HK_EMAC2, K2HK_EMAC3 122Hit any key to stop autoboot: 0 123 124SPI NOR Flash programming instructions 125====================================== 126U-Boot image can be flashed to first 512KB of the NOR flash using following 127instructions: 128 1291. Start CCS and run U-Boot as described above. 1302. Suspend Target. Select Run -> Suspend from top level menu 131 CortexA15_1 (Free Running)" 1323. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000 133 through CCS as described in step 2 of "Load and Run U-Boot on K2HK/K2E/K2L 134 EVM using CCS", but using address 0x87000000. 1354. Free Run the target as described earlier (step 4) to get U-Boot prompt 1365. At the U-Boot console type following to setup U-Boot environment variables. 137 setenv addr_uboot 0x87000000 138 setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000> 139 run burn_uboot_spi 140 Once U-Boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 141 to "SPI Little Endian Boot mode" as per instruction at 142 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1436. Power ON the EVM. The EVM now boots with U-Boot image on the NOR flash. 144 145AEMIF NAND Flash programming instructions 146====================================== 147U-Boot image can be flashed to first 1024KB of the NAND flash using following 148instructions: 149 1501. Start CCS and run U-Boot as described above. 1512. Suspend Target. Select Run -> Suspend from top level menu 152 CortexA15_1 (Free Running)" 1533. Load MLO binary from build folder on to DDR address 0x87000000 154 through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM 155 using CCS", but using address 0x87000000. 1564. Free Run the target as described earlier (step 4) to get U-Boot prompt 1575. At the U-Boot console type following to setup U-Boot environment variables. 158 setenv filesize <size in hex of MLO rounded to hex 0x10000> 159 run burn_uboot_nand 160 Once U-Boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 161 to "ARM NAND Boot mode" as per instruction at 162 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 1636. Power ON the EVM. The EVM now boots with U-Boot image on the NAND flash. 164 165Load and Run U-Boot on keystone EVMs using UART download 166======================================================== 167 168Open BMC and regular UART terminals. 169 1701. On the regular UART port start xmodem transfer of the u-boot-dtb.bin 1712. Using BMC terminal set the ARM-UART bootmode and reboot the EVM 172 BMC> bootmode #4 173 MBC> reboot 1743. When xmodem is complete you should see the U-Boot starts on the UART port 175
