| 11 | Building U-boot for Hummingboard |
| 12 | -------------------------------- |
| 13 | |
| 14 | To build U-Boot for the Hummingboard Solo version: |
| 15 | |
| 16 | $ make hummingboard_solo_config |
| 17 | $ make |
| 18 | |
| 19 | Flashing U-boot into the SD card |
| 20 | -------------------------------- |
| 21 | |
| 22 | - After the 'make' command completes, the generated 'u-boot.imx' binary must be |
| 23 | flashed into the SD card: |
| 24 | |
| 25 | $ sudo dd if=u-boot.imx of=/dev/mmcblk0 bs=1k seek=1; sync |
| 26 | |
| 27 | (Note - the SD card node may vary, so adjust this as needed). |
| 28 | |
| 29 | Also, a more detailed explanation on how to format the SD card is available |
| 30 | at doc/README.imximage. |
| 31 | |
| 32 | - Insert the micro SD card into the slot located in the bottom of the board |
| 33 | |
| 34 | - Connect a 3.3V USB to serial converter cable to the host PC. The MX6 UART |
| 35 | signals are available in the 26 pin connector as shown at: |
| 36 | http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware |
| 37 | (Check for "26 pin header layout"). |
| 38 | |
| 39 | - Power up the board via USB cable (CON201) and U-boot messages will appear in |
| 40 | the serial console. |
