|
|
|
||

============
|
||
|
|
|
||
|
|
- Put warpboard in USB download mode by closing the j2 jumper on the
|
||
|
|
daugther board
|
||
|
|
|
||
|
|
- Load u-boot.imx in the WarpBoard by using the imx-usb-loader host utility:
|
||
|
|
|
||
|
|
$ ./output/host/bin/imx_usb -c output/host/etc/imx-loader.d/ output/images/u-boot.imx
|
||
|
|
|
||
|
|
- U-Boot will appear in minicom
|
||
|
|
|
||
|
|
- Reset the U-Boot environment to its default:
|
||
|
|
=> env default -f -a
|
||
|
|
=> saveenv
|
||
|
|
|
||
|
|
- Run the DFU command in U-Boot:
|
||
|
|
=> dfu 0 mmc 0
|
||
|
|
|
||
|
|
- Transfer U-Boot into flash by running this command in host side:
|
||
|
|
|
||
|
|
$ sudo ./output/host/bin/dfu-util -D output/images/u-boot.imx -a boot
|
||
|
|
|
||
|
|
- remove power and put the WarpBoard back into normal boot mode by
|
||
|
|
opening the j2 jumper.

||
|
|
|
||
|
|
Update linux & rootfs
|
||
|
|

|
||
|
|
|

|
|
Run the 'ums' command from the U-Boot prompt to mount the eMMC as USB mass
|
||
|
|
storage:
|
||
|
|
|
||
|
|
=> ums 0 mmc 0
|
||
|
|
|
||
|
|
And then flash the sdcard.img into the eMMC:
|
||
|
|
|
||
|
|
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
|
||
|
|
|
