Oh, I forgot to mention, that I do not have the original firmware dump, because first I managed to brick the camera when I tried to update it through some firmware update tool, via ETH, and only then I bought a UARTtoUSB stick and 'wired' the camera's port.

Hi, Please help me with a dump of the SPI for IPCAM HI3516EV200 with IMX307 sensor (1080P/ 2MP Sony), SD card and WiFi. I connected the camera through UART to my desktop. I can write OpenIPC on it, but I would like to put back the 'original' firmware, because it was easier to use. I remember...

I set these values for bootargs and bootcmd: setenv bootargs 'mem=40M console=ttyAMA0,115200 panic=20 root=/dev/mtdblock3 rootfstype=squashfs init=/init mtdparts=hi_sfc:256k(boot),64k(env),2048k(kernel),5120k(rootfs),-(rootfs_data)' setenv bootcmd 'sf probe 0; sf read 0x42000000 0x50000...

It finally worked. I found these hard to find instructions: https://github.com/OpenIPC/openipc-2.1/wiki/install_hisi and I updated bootargs, bootcmd Now I need to find and restore some kind of 'original' firmware. Is it posible to use the tftp and manufacturer's update tools?

Thanks for the quick reply. I am not sure what I am doing there. I copied the mtdparts from some other printenv-s, from different forums. uImage has 1.77 MB (1,857,096 bytes) rootfs.squshfs has 4.81 MB (5,046,272 bytes) So, in fact , after the failed firmware upgrade, I messed up bootcmd...

Hello again, I managed to copy on SPI NOR uImage and rootfs, like this: And then setenv: bootargs=mem=40M console=ttyAMA0,115200 root=/dev/mtdblock3 rootfstype=squashfs bootcmd=sf probe 0;sf read 0x42000000 0x50000 0x250000;bootm 0x42000000 mtdparts=hi_sfc:256K(boot),2M(kernel),5M(rootfs)...

Hi. I am having trouble unbricking my IPCam. I tried upgrading the firmware by renaming a different package to V20.1.23.6.x, as my original release was. I connected UART to CH340G chip and I have access to U-Boot: (pass HI2105CHIP) U-Boot 2016.11 (Apr 03 2019 - 18:54:33 +0800)hi3516ev200...

Hi, I ended up here after, of course, bricking my chinese camera. Hi3516 V200 chip. https://www.aliexpress.com/item/33050505819.html?spm=a2g0s.9042311.0.0.27424c4ddKBfAN It had firmware V20.1.23.6.5 or something. It did not have "Humanoid alarm" option and I tried to put a different firmware. I...
