### Upgrade HI3536 NVR board to OpenIPC FPV firmware

- download actual [firmware](https://github.com/OpenIPC/firmware/releases/download/latest/openipc.hi3536dv100-nor-fpv.tgz) from OpenIPC site
- unpack firmware archive to your TFTP server
- connect UART adapter to NVR board
- go to u-boot (press Ctrl+C)
- execute a set of commands each line separately, changing the ip address of the nvr board and the ip address of your tftp server

```
