Flashing the SD card image
|
||
|
|
==========================
|
||
|
|
|
||
|
|
To install the image on a SDCard simply copy sdcard.img to the storage (e.g. SD, eMMC)
|
||
|
|
|
||
|
|
$ sudo dd if=output/images/sdcard.img of=<your-sd-device>
|
||
|
|
|
||
|
|
|
||
|
|
Preparing the board
|
||
|
|
===================
|
||
|
|
|
||
|
|
* Connect a serial line to the board
|
||
|
|
* Insert the SD card
|
||
|
|
* Power-up the board
|
||
|
|
|
||
|
|
|
||
|
|
Booting the board
|
||
|
|
=================
|
||
|
|
|
||
|
|
By default the bootloader will search for the first valid image, starting
|
||
|
|
with the internal eMMC. To make sure the bootloader loads bootscript from
|
||
|
|
the correct location (SD card) set the boot_targets environment variable:
|
||
|
|
|
||
|
|
$ setenv boot_targets mmc1
|
