How to Update U-Boot on Warp7 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/ (if you are in a
|
|
Debian distribution then you can get it via libdfu-dev package)
|
|
|
|
- libusb: http://libusb.org/ (if you are in a Debian distribution
|
|
then you can get it via libusb-dev and libusb-1.0-0-dev)
|
|
|
|
In U-Boot folder, build U-Boot for Warp7:
|
|
|
|
$ make mrproper
|
|
$ make warp7_config
|
|
$ make
|
|
|
|
This will generate the U-Boot binary called u-boot-dtb.imx.
|
|
|
|
Put warp7 board in USB download mode:
|
|
|
|
Remove the CPU board from the base board then put switch 2 in the upper
|
|
position
|
|
|
|
Connect a USB to serial adapter between the host PC and warp7
|
|
|
|
Connect a USB cable between the OTG warp7 port and the host PC
|
|
|
|
Copy u-boot-dtb.imx to the imx_usb_loader folder.
|
|
|
|
Load u-boot-dtb.imx via USB:
|
|
|
|
$ sudo ./imx_usb u-boot-dtb.imx
|
|
|
|
Then U-Boot should start and its messages will appear in the console program.
|
|
|
|
Open a terminal program such as minicom
|
|
|
|
Use the default environment variables:
|
|
|
|
=> env default -f -a
|
|
=> saveenv
|
|
|
|
Run the DFU command:
|
|
=> dfu 0 mmc 0
|
|
|
|
Transfer u-boot-dtb.imx that will be flashed into the eMMC:
|
|
|
|
$ sudo dfu-util -D u-boot-dtb.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 warp7 board.
|
|
|
|
Put warp7 board into normal boot mode (put the switch 2 in the lower position)
|
|
|
|
Power up the board and the new updated U-Boot should boot from eMMC
