**IMPORTANT NOTE: THIS REPOSITORY SEEMS TO BE OBSOLETE.** **THE CURRENT GM8135S BOARDS NOW COME WITH A DIFFERENT UBOOT VERSION THAT NO LONGER SUPPORTS THE FLWRITE COMMAND.** **USE AT OWN RISK !** Customized Firmware for cheap chinese ip-cameras with GM8135S chipset --------------------------------------------------------------------- Most of the GM8135S cameras usually come with firmware V4.02.R12.00017502.10010.042399.00000 The problem with this firmware is that it does not have a web-interface or has any alternative way to update firmware or change settings, so it makes the camera quite useless. I modified the firmware (based on fw-image: General_HZXM_IPC_GM8135S__50V10PL-S_V4.02.R12.Nat.OnvifS..20160407.bin) and made the following changes: - telnet service on port 23 ( username: root ; password: xmhdipc ) - web-interface, so the camera can be fully configured and accessed. to upload the modified files you need to connect via UART (usually located on the 3 blamk connection pins on top of the camera board) once connected through UART and you can see the boot process, disrupt boot (camera ip will be 192.168.1.10) start a tftp server on ip 192.168.1.107 and serve the xxx.cramfs.img files on a pc > on the camera enter the following (at the uboot prompt): # setenv appSystemLanguage English;setenv bootdelay 5;saveenv > install modified firmware files: # tftp 0x2000000 custom.cramfs.img;flwrite;tftp 0x2000000 user_web.cramfs.img;flwrite > do not disconnect power to restart or reboot, as this may cause corruption or other unwanted problems. > it's best to enter the following command after uploading the files and/or to reboot the camera: # run bootcmd > alternatively, if you need a semi full restore/recovery > important note : uboot (on partition mtd0) must still work !! otherwise camera will be dead and can not be recovered ! # tftp 0x2000000 custom.cramfs.img;flwrite;tftp 0x2000000 romfs-x.cramfs.img;flwrite # tftp 0x2000000 user-web.cramfs.img;flwrite;tftp 0x2000000 web-x.cramfs.img;flwrite # run bootcmd ---------------------------------------------------------------------------------------------------------- details: http://www.grain-media.com/html/8136S_8135S.htm
