__ATTENTION! Upgrading firmware can lead to "bricking" your camera. Make sure you are prepared both morally and skillwise. Have your rescue SD card and/or UART adapter ready. Be prepared to desolder and reprogram flash chip as the last resort. Do not upgrade production cameras unless you really have to!__
### Upgrading from a TFTP server
[Set up a TFTP server](installation-tftpd.md).
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.
Extract content of the bundle into the root directory of your TFTP server.
On the camera run:
#### From Linux
```
soc=$(fw_printenv -n soc)
serverip=$(fw_printenv -n serverip)

### Flashing U-Boot via ymodem
Clean 320K of RAM amd load bootloader file into it:
```
mw.b ${baseaddr} 0xff 0x50000
loady
```
_(press "Ctrl-a" followed by ":", then type)_
```
exec !! sz --ymodem u-boot.bin
```
After the file if uploaded, write it into ROM:
```
sf probe 0
sf erase 0x0 0x50000
sf write ${baseaddr} 0x0 ${filesize}
```
