35There are only 2 eth port installed on the boards.
36
37There are separate PLLs to drive clocks to Tetris ARM and Peripherals.
38To bring up SMP Linux on this board, there is a boot monitor
39code that will be installed in MSMC SRAM. There is command available
40to install this image from u-boot.

83Load and Run U-Boot on keystone EVMs using CCS
84=========================================
85
86Need Code Composer Studio (CCS) installed on a PC to load and run u-boot.bin
87on EVM. See instructions at below link for installing CCS on a Windows PC.
88http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Getting_Started#
89Installing_Code_Composer_Studio
90Use u-boot.bin from the build folder for loading and running u-boot binary
91on EVM. Follow instructions at
92K2HK http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup
93K2E  http://processors.wiki.ti.com/index.php/EVMK2E_Hardware_Setup
94K2L  http://processors.wiki.ti.com/index.php/TCIEVMK2L_Hardware_Setup
95
96to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode"
97and Power ON the EVM.  Follow instructions to connect serial port of EVM to
98PC and start TeraTerm or Hyper Terminal.
99
100Start CCS on a Windows machine and Launch Target
101configuration as instructed at http://processors.wiki.ti.com/index.php/
102MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS.
103The instructions provided in the above link uses a script for
104loading the u-boot binary on the target EVM. Instead do the following:-
105
1061. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D
107   is connected: Unknown)" at the debug window (This is created once Target
108   configuration is launched) and select "Connect Target".
1092. Once target connect is successful, choose Tools->Load Memory option from the
110   top level menu. At the Load Memory window, choose the file u-boot.bin
111   through "Browse" button and click "next >" button. In the next window, enter
112   Start address as 0xc001000, choose Type-size "32 bits" and click "Finish"
113   button.
1143. Click View -> Registers from the top level menu to view registers window.
1154. From Registers, window expand "Core Registers" to view PC. Edit PC value
116   to be 0xc001000. From the "Run" top level menu, select "Free Run"
1175. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as
118   below and type any key to stop autoboot as instructed :=

131SPI NOR Flash programming instructions
132======================================
133U-Boot image can be flashed to first 512KB of the NOR flash using following
134instructions:
135
1361. Start CCS and run U-boot as described above.
1372. Suspend Target. Select Run -> Suspend from top level menu
138   CortexA15_1 (Free Running)"
1393. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000
140   through CCS as described in step 2 of "Load and Run U-Boot on K2HK/K2E/K2L
141   EVM using CCS", but using address 0x87000000.
1424. Free Run the target as described earlier (step 4) to get u-boot prompt
1435. At the U-Boot console type following to setup u-boot environment variables.
144   setenv addr_uboot 0x87000000
145   setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000>
146   run burn_uboot_spi
147   Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
148   to "SPI Little Endian Boot mode" as per instruction at
149   http://processors.wiki.ti.com/index.php/*_Hardware_Setup.
1506. Power ON the EVM. The EVM now boots with u-boot image on the NOR flash.
151
152AEMIF NAND Flash programming instructions
153======================================
154U-Boot image can be flashed to first 1024KB of the NAND flash using following
155instructions:
156
1571. Start CCS and run U-boot as described above.
1582. Suspend Target. Select Run -> Suspend from top level menu
159   CortexA15_1 (Free Running)"
1603. Load u-boot-nand.gph binary from build folder on to DDR address 0x87000000
161   through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
162   using CCS", but using address 0x87000000.
1634. Free Run the target as described earlier (step 4) to get u-boot prompt
1645. At the U-Boot console type following to setup u-boot environment variables.
165   setenv filesize <size in hex of u-boot-nand.gph rounded to hex 0x10000>
166   run burn_uboot_nand
167   Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
168   to "ARM NAND Boot mode" as per instruction at
169   http://processors.wiki.ti.com/index.php/*_Hardware_Setup.
1706. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash.
