How to Update U-boot on Warp board
|
|
----------------------------------
|
|
|
|
Required software on the host PC:
|
|
|
|
- imx_usb_loader: https://github.com/boundarydevices/imx_usb_loader
|
|
|
|
- dfu-util: http://dfu-util.sourceforge.net/releases/
|
|
|
|
Build U-boot for Warp:
|
|
|
|
$ make mrproper
|
|
$ make warp_config
|
|
$ make
|
|
|
|
This will generate the U-boot binary called u-boot.imx.
|
|
|
|
Put warp board in USB download mode
|
|
|
|
Connect a USB to serial adapter between the host PC and warp
|
|
|
|
Connect a USB cable between the OTG warp port and the host PC
|
|
|
|
Open a terminal program such as minicom
|
|
|
|
Copy u-boot.imx to the imx_usb_loader folder.
|
|
|
|
Load u-boot.imx via USB:
|
|
|
|
$ sudo ./imx_usb u-boot.imx
|
|
|
|
Then U-boot should start and its messages will appear in the console program.
|
|
|
|
Use the default environment variables:
|
|
|
|
=> env default -f -a
|
|
=> saveenv
|
|
|
|
Run the DFU command:
|
|
=> dfu 0 mmc 0
|
|
|
|
Transfer u-boot.imx that will be flashed into the eMMC:
|
|
|
|
$ sudo dfu-util -D u-boot.imx -a boot
|
|
|
|
Then on the U-boot prompt the following message should be seen after a
|
|
successful upgrade:
|
|
|
|
#DOWNLOAD ... OK
|
|
Ctrl+C to exit ...
|
|
|
|
Remove power from the warp board.
|
|
|
|
Put warp board into normal boot mode
|
|
|
|
Power up the board and the new updated U-boot should boot from eMMC
