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 :=

172
173 Load and Run U-Boot on keystone EVMs using UART download
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
184 Load and Run U-Boot on K2G EVMs using MMC
185 ========================================================
186
187 Open BMC and regular UART terminals.
188
189 1. Set the SW3 dip switch to "ARM MMC Boot mode" as per instruction at
190 http://processors.wiki.ti.com/index.php/66AK2G02_GP_EVM_Hardware_Setup
191 2. Create SD card partitions as per steps given in Hardware Setup Guide.
192 3. Copy MLO to Boot Partition.
193 4. Insert SD card and Power on the EVM.
