| |
| There are only 2 eth port installed on the boards. |
| |
| There are separate 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 |

| |
| Build instructions: |
| =================== |
| Examples for k2hk, for k2e, k2l and k2g just replace k2hk prefix accordingly. |
| Don't forget to add ARCH=arm and CROSS_COMPILE. |
| |
| To build u-boot.bin, u-boot-spi.gph, MLO: |
| >make k2hk_evm_defconfig |
| >make |
| |
| Load and Run U-Boot on keystone EVMs 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 and running U-Boot binary |
| on EVM. Follow instructions at |
| K2HK http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup |
| K2E http://processors.wiki.ti.com/index.php/EVMK2E_Hardware_Setup |
| K2L http://processors.wiki.ti.com/index.php/TCIEVMK2L_Hardware_Setup |
| K2G http://processors.wiki.ti.com/index.php/66AK2G02_GP_EVM_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 |
| is connected: 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 0xc000000, 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 0xc000000. 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/K2E/K2L |
| EVM using CCS", but using address 0x87000000. |
| 4. Free Run the target as described 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/*_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 MLO 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 described 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 MLO 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/*_Hardware_Setup. |
| 6. Power ON the EVM. The EVM now boots with U-Boot image on the NAND flash. |
| |
| Load and Run U-Boot on keystone EVMs using UART download |
| ======================================================== |
| |
| Open BMC and regular UART terminals. |
| |
| 1. On the regular UART port start xmodem transfer of the u-boot.bin |
| 2. Using BMC terminal set the ARM-UART bootmode and reboot the EVM |
| BMC> bootmode #4 |
| MBC> reboot |
| 3. When xmodem is complete you should see the U-Boot starts on the UART port |
| |
| Load and Run U-Boot on K2G EVMs using MMC |
| ======================================================== |
| |
| Open BMC and regular UART terminals. |
| |
| 1. Set the SW3 dip switch to "ARM MMC Boot mode" as per instruction at |
| http://processors.wiki.ti.com/index.php/66AK2G02_GP_EVM_Hardware_Setup |
| 2. Create SD card partitions as per steps given in Hardware Setup Guide. |
| 3. Copy MLO to Boot Partition. |
| 4. Insert SD card and Power on the EVM. |
| The EVM now boots with U-Boot image from SD card. |
