### Flashing full image from TFTP
Before you start, [prepare the enviroment](#prepare-the-enviroment).
Download [full image binary for your SoC](https://openipc.org/supported-hardware/)
and place it in the root directory of your local FTFP server.
Start the session and boot into the bootloader console interrupting booting
routine with a key combo. When in the console, set up parameters of your local
network, if needed.
```
setenv ipaddr 192.168.1.10
setenv netmask 255.255.255.0
setenv gatewayip 192.168.1.1
setenv serverip 192.168.1.254
```
Use the following commands to reflash your camera with the full image:
Example for 8MB:
```
mw.b ${baseaddr} 0xff ${flashsize}
tftpboot ${baseaddr} openipc-${soc}-lite-8mb.bin
sf probe 0; sf erase 0x0 ${flashsize}; sf write ${baseaddr} 0x0 ${filesize}
reset
```
Example for 16MB:
```
mw.b ${baseaddr} 0xff ${flashsize}
tftpboot ${baseaddr} openipc-${soc}-ultimate-16mb.bin
sf probe 0; sf erase 0x0 ${flashsize}; sf write ${baseaddr} 0x0 ${filesize}
reset
```
At the first boot, sign in into the bootloader shell once again and remap
partitioning running `run setnor16m` command.
