U-Boot for SolidRun Hummingboard
--------------------------------
This file contains information for the port of U-Boot to the Hummingboard.
For more details about Hummingboard, please refer to:
http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware
(Carrier-One was the previous name of Hummingboard).
Building U-boot for Hummingboard
--------------------------------
To build U-Boot for the Hummingboard Solo version:
$ make hummingboard_solo_config
$ make
Flashing U-boot into the SD card
--------------------------------
- After the 'make' command completes, the generated 'u-boot.imx' binary must be
flashed into the SD card:
$ sudo dd if=u-boot.imx of=/dev/mmcblk0 bs=1k seek=1; sync
(Note - the SD card node may vary, so adjust this as needed).
Also, a more detailed explanation on how to format the SD card is available
at doc/README.imximage.
- Insert the micro SD card into the slot located in the bottom of the board
- Connect a 3.3V USB to serial converter cable to the host PC. The MX6 UART
signals are available in the 26 pin connector as shown at:
http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware
(Check for "26 pin header layout").
- Power up the board via USB cable (CON201) and U-boot messages will appear in
the serial console.
