Wyze integration

This is where we'll be writing down our guide to flashing new devices and reports on our experiments.

Current issues

  • Exposure does not work well https://github.com/OpenIPC/majestic/issues/102
  • SD card does not work in the U-Boot (power is available) fixed
  • Problem with loading u-boot from an microSD card. It doesn't reach the promt. Not only on wyze v3 (https://t.me/openipc_modding/179369), but also on another board T31L (https://t.me/openipc/47739). Most likely it will be IMPOSSIBLE, because in the camera there is a microSD power management MOSFET, which must be turned on BEFORE booting from the card (the experiment with not fully loaded u-boot was possible due to direct power supply to the microSD card, bypassing the transistor). Please confirm my version if it is not possible otherwise. impossible without modification (direct 3.3V power supply to the microSD card reader)

Known camera modifications

  • WYZE Cam v3 and WYZE Cam Pan v3

OpenIPC installation

  • Disassemble camera and connect UART adapter or your camera should be already connected to network.

  • Backup

Downgrade original firmware version to (Jun 2021 w-o internet)demo_wcv3_4.36.2.5.bin (WYom20200 Jun 2021 w-o internet)demo_wcv3_4.36.2.5.bin.zip

Login with user root password WYom20200 via telnet or UART console. Insert microSD card to camera and issue command:

for mtd in $(ls /dev/mtdblock*); do dd if=${mtd} of=/media/mmc/${mtd##/*/}.bin; done

Output sample:

If there wasn't errors, then you backed up such partitions:

[root@WCV3:~]# cat /proc/mtd

Check if files on microSD card with command ls -la /media/mmc/

Save and keep this files in safe place. In case of any errors you should perform this operation once again, probably with microSD card replacement.

  • Determine SoC model

Download ipctool-mips32 to microSD card (https://github.com/OpenIPC/ipctool/releases/download/latest/ipctool-mips32) and insert microSD card in camera. Login to camera and issue command /media/mmc/ipctool-mips32 There should be something like model: T31ZX in console output. Important part is ZX

Output sample:

[root@WCV3:~]# /media/mmc/ipctool-mips32

  • Flash OpenIPC U-boot

Open https://openipc.org/cameras/vendors/ingenic and choose appropriate SoC model from list.

In this case our choice Ingenic T31X.

In Downloads section find OpenIPC Bootloader for Ingenic T31X and download it.

https://github.com/OpenIPC/firmware/releases/download/latest/u-boot-t31x-universal.bin

Copy u-boot-t31x-universal.bin to microSD card and insert microSD card in camera.

telnet would be unavailable after the command below (flashcp) !

Login to camera and issue command: flashcp -v /media/mmc/u-boot-t31x-universal.bin /dev/mtd0

Output sample:

[root@WCV3:~]# flashcp -v /media/mmc/u-boot-t31x-universal.bin /dev/mtd0
Erasing block: 8/8 (100%) 
Writing kb: 242/242 (100%) 
Verifying kb: 242/242 (100%)

Now your camera flashed with OpenIPC U-boot, but whole system is still stock. So, next re/boot will load OpenIPC U-boot only (in cycling mode, until stop with Ctrl+C in UART console).

  • Flash kernel and rootfs

Since we identified our chip as Ingenic T31X open https://openipc.org/cameras/vendors/ingenic and choose T31X.

In Downloads section find OpenIPC Linux (Lite) for Ingenic T31X and download it.

https://github.com/OpenIPC/firmware/releases/download/latest/openipc.t31-nor-lite.tgz

Power off the camera.

Extract and copy rootfs.squashfs.t31 uImage.t31 to microSD card. Insert microSD card in camera.

Power on the camera.

During power on the camera press Ctrl+C several times until it shows OpenIPC prompt like this OpenIPC #

Then issue command run setnor16m

After you press the Enter key the camera will almost immediately restart and you will have to catch the prompt again.

Then issue command:

mw.b ${baseaddr} ff 1000000; fatload mmc 0:1 ${baseaddr} uImage.${soc} ; sf probe 0; sf erase 0x50000 0x300000; sf write ${baseaddr} 0x50000 ${filesize}

and next:

mw.b ${baseaddr} ff 1000000; fatload mmc 0:1 ${baseaddr} rootfs.squashfs.${soc} ; sf probe 0; sf erase 0x350000 0xa00000; sf write ${baseaddr} 0x350000 ${filesize}

Output sample:

OpenIPC # mw.b ${baseaddr} ff 1000000; fatload mmc 0:1 ${baseaddr} uImage.${soc} ; sf probe 0; sf erase 0x50000 0x300000; sf write ${baseaddr} 0x50000 ${filesize}

If everything went well, issue the command reset and camera should start boot OpenIPC.
