| 1f9d1cf6 FE |
2 | ---------------------------------- |
| 3 | ||
| 4 | Required software on the host PC: | |
| 5 | ||
| 6 | - imx_usb_loader: https://github.com/boundarydevices/imx_usb_loader | |
| 7 | ||
| 8 | - dfu-util: http://dfu-util.sourceforge.net/releases/ | |
| 9 | ||
| a187559e | 10 | Build U-Boot for Warp: |
| 1f9d1cf6 FE |
11 | |
| 12 | $ make mrproper | |
| 13 | $ make warp_config | |
| 14 | $ make | |
| 15 | ||
| a187559e | 16 | This will generate the U-Boot binary called u-boot.imx. |
| 1f9d1cf6 FE |
17 | |
| 18 | Put warp board in USB download mode | |
| 19 | ||
| 20 | Connect a USB to serial adapter between the host PC and warp | |
| 21 | ||
| 22 | Connect a USB cable between the OTG warp port and the host PC | |
| 23 | ||
| 24 | Open a terminal program such as minicom | |
| 25 | ||
| 26 | Copy u-boot.imx to the imx_usb_loader folder. | |
| 27 | ||
| 28 | Load u-boot.imx via USB: | |
| 29 | ||
| 30 | $ sudo ./imx_usb u-boot.imx | |
| 31 | ||
| a187559e | 32 | Then U-Boot should start and its messages will appear in the console program. |

33 | |
| 34 | Use the default environment variables: | |
| 35 | ||
| 36 | => env default -f -a | |
| 68006aeb | 37 | => saveenv |
| 1f9d1cf6 FE |
38 | |
| 39 | Run the DFU command: | |
| 40 | => dfu 0 mmc 0 | |
| 41 | ||
| 42 | Transfer u-boot.imx that will be flashed into the eMMC: | |
| 43 | ||
| 44 | $ sudo dfu-util -D u-boot.imx -a boot | |
| 45 | ||
| a187559e | 46 | Then on the U-Boot prompt the following message should be seen after a |
| e719cdde | 47 | successful upgrade: |

| 52 | Remove power from the warp board. | |
| 53 | ||
| 54 | Put warp board into normal boot mode | |
| 55 | ||
| a187559e | 56 | Power up the board and the new updated U-Boot should boot from eMMC |
