Free Run the target as described earlier (step 4) to get U-Boot prompt 165 5. At the U-Boot console type following to setup U-Boot environment variables. 166 setenv filesize <size in hex of MLO rounded to hex 0x10000> 167 run burn_uboot_nand 168 Once U-Boot prompt is available, Power OFF the EVM. Set the SW1 dip switch 169 to "ARM NAND Boot mode" as per instruction at 170 http://processors.wiki.ti.com/index.php/*_Hardware_Setup. 171 6. Power ON the EVM. The EVM now boots with U-Boot image on the NAND flash. 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. 194 The EVM now boots with U-Boot image from SD card. 195
