8.2. Encoder Application
The fw_update application allows you to update microcontroller firmware. To update microcontroller's firmware you should switch your microcontroller to firmware mode and connect it to USB. The fw_update application supports the following commands(Table 8.3, “Fw_update commands”):
Table 8.3. Fw_update commands
| Short Command | Full Command | Description |
|---|---|---|
| -w | -write | Write data to device. |
| -r | -read | Read data from device. |
| -v | -verify | Verify device memory. |
| -e | -erase | Erase device memory. |
| -ver | -version | Display versions of fw_update and Bootloader if present. |
| -h | -help | Displays the supported commands and options description. |
The fw_update application supports the following options(Table 8.4, “Fw_update options”):
Table 8.4. Fw_update options
| Short Option | Full Option | Parameter Value | Description |
|---|---|---|---|
| -m | -memory | MEMORY TYPE | Memory type for read, write and verify operations. Possible values: flash, eeprom, id, all. Default: flash. |
| -vid | -vendorid | VID | Device vendor ID. |
| -pid | -productid | PID | Device product ID. |
| -t | -reset | YES | NO | Reset device after operation is finished. Default: YES |
| -s | -size | SIZE | The data size for read, write and verify operations. |
| -a | -address | ADDR | The start address for read, write and verify operations. Default: 0x800 for flash, 0x00 for other memory types. |
| -ix | -image_hex_in | FILENAME | Image file in Intel Hex Format for write and verify operations. |
| -ib | -image_bin_in | FILENAME | Image file in Binary Format for write and verify operations. |
| -ox | -image_hex_out | FILENAME | Image file in Intel Hex Format for read operation to save data. |
| -ob | -image_bin_out | FILENAME | Image file in Binary Format for read operation to save data. |
| -d | -data | DATA | Immediate mode - actual byte(s) specified in the command line. Data for write and verify operations must be provided as string of two hex digits per byte (like 01202040ac). For read operation data is printed on screen. |
For instanse, we need to perform microcontroller firmware update. The command line for such operation is:
fw_update -e -w -v -vid 0x04D8 -pid 0xFF04 -ix example_encrypted.hex
