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

### 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](https://github.com/OpenIPC/wiki/files/10755387/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:
```
[root@WCV3:~]# for mtd in $(ls /dev/mtdblock*); do dd if=${mtd} of=/media/mmc/${mtd##/*/}.bin; done

If there wasn't errors, then you backed up such partitions:
```
[root@WCV3:~]# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00008000 "boot"
mtd1: 001f0000 00008000 "kernel"
mtd2: 003d0000 00008000 "rootfs"
mtd3: 003d0000 00008000 "app"
mtd4: 001f0000 00008000 "kback"
mtd5: 003d0000 00008000 "aback"
mtd6: 00060000 00008000 "cfg"
mtd7: 00010000 00008000 "para"
```
Check if files on microSD card with command `ls -la /media/mmc/`
```
[root@WCV3:~]# ls -la /media/mmc/
drwxr-xr-x 7 root root 8192 May 14 01:52 .

-rwxr-xr-x 1 root root 65536 May 14 01:52 mtdblock7.bin
```
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:
```bash
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:
```bash
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:
```shell
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.
