## Erasing Flash Settings
The flash settings are stored in the last flash sector(ID: 11) of bank 0 of stm32f405. You can erase it with JTAG/SWD adapter or by putting the device in Dfu mode. You may find it useful if you have set network settings incorrectly.

With JTAG/SWD adapter connected, issue the following command:
```shell
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c "flash init; init; halt; flash erase_sector 0 11 last; reset; exit"
