### 2.2 Upgrade via dfu-util
|
||
|
|
|
||
|
|
1. Navigate to the root directory of the dfu-util executable file:
|
||
|
|
`dfu-util-0.11-binaries\win64` or `dfu-util-0.11-binaries\win32`, depending on your Windows version. The following instructions are for the win64 version.
|
||
|
|
|
||
|
|
2. Enter the command `dfu-prefix.exe --version`
|
||
|
|
|
||
|
|
3. Receive the prompt "please report bugs to http://sourceforge.net/p/dfu-util/tickets/" to indicate success.
|
||
|
|
|
||
|
|
4. Copy the firmware to be upgraded into the `dfu-util-0.11-binaries\win64` directory.
|
||
|
|
|
||
|
|
5. Enter the command: `dfu-util -e -d 4000 -a 1 -D example_ffva_ua_adec_upgrade.bin`
|
||
|
|
Note that `example_ffva_ua_adec_upgrade.bin` is a placeholder and should be replaced with the actual firmware file name you wish to upgrade.
|
||
|
|
|
||
|
|
6. After running, **you will receive the following prompts indicating a successful upgrade**:
