This board consist of Hi3516cv300 CPU and Sony IMX291 chip. Can be bought on AliExpress or other marketplaces.
This instruction is based on the information from OpenIPC project and with the help of it's community.
Currently not supported:
* Night mode (based on IR sensor and IR curtain shutter)
Download and put all the binaries in the TFTP folder:
openwrt-hi35xx-16cv300-u-boot.bin
Currently it is not possible to flash the board without UART access. Connect the UART terminal to the board.
Poweroff and turn on the board.
Press Ctrl+C in U-boot start
* From here on we will assume that the device will have 192.168.1.10 and TFTP server 192.168.1.254
Execute the following code in Uboot:
setenv ipaddr 192.168.1.10 setenv serverip 192.168.1.254 sf probe 0 mw.b 0x82000000 ff 2000000 sf read 0x82000000 0x0 0x2000000 tftp 0x82000000 fullflash.img 0x2000000
Check that TFTP server received the backup image.
NB! As the next step is important it is advised to run below mentioned commands in order they are grouped.
Also check that all binary images are downloaded successfully via TFTP.
Upon successful download there will be information of actually downloaded bytes. Example:
Downloading: ################################################# done Bytes transferred = 3967018 (3c882a hex)
setenv ipaddr 192.168.1.10
setenv serverip 192.168.1.254
