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)
  • 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.

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 Issue commands line by line, not all together:

dd if=/dev/mtd0 of=/media/mmc/mtd0.bin

dd if=/dev/mtd1 of=/media/mmc/mtd1.bin

dd if=/dev/mtd2 of=/media/mmc/mtd2.bin

dd if=/dev/mtd3 of=/media/mmc/mtd3.bin

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"

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.
