 101 Start CCS on a Windows machine and Launch Target
 102 configuration as instructed at http://processors.wiki.ti.com/index.php/
 103 MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS.
 104 The instructions provided in the above link uses a script for
 105 loading the U-Boot binary on the target EVM. Instead do the following:-
 106
 107 1. 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".
 110 2. 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 0xc000000, choose Type-size "32 bits" and click "Finish"
 114    button.
 115 3. Click View -> Registers from the top level menu to view registers window.
 116 4. From Registers, window expand "Core Registers" to view PC. Edit PC value
 117    to be 0xc000000. From the "Run" top level menu, select "Free Run"
 118 5. 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 :=

 174 ========================================================
 175
 176 Open BMC and regular UART terminals.
 177
 178 1. On the regular UART port start xmodem transfer of the u-boot.bin
 179 2. Using BMC terminal set the ARM-UART bootmode and reboot the EVM
 180    BMC> bootmode #4
 181    MBC> reboot
 182 3. When xmodem is complete you should see the U-Boot starts on the UART port
 183

 185 ========================================================
 186
 187 Open BMC and regular UART terminals.
 188
