Bugs/Implementation plan

1. (Not a bug) Backup operation with dry_run enabled generates a directory contains only ID.txt

This behavior works as intended. The partition images are not backed up because the program didn't touch the partitions at all.

2. (Improvement) Make writing a new profile easier

This is a good idea. It could be done by declaring a profile using a json file and write a script to parse it.

However, doing this makes the program lose its flexibility for partition manipulation. Currently there are still a lot of things have not been implemented(eg. manipulate UBI volumes). If it is implemented, it will be the very last thing to be implemented.

Roadmap

v1.0.0

• Complete support for NAND flash
  • Backup/restore UBI volumes
  • Bad block management for regular partitions

I flashed my Wyze v3 (T31x) via wz_flash-helper with:

• latest u-boot from @gtxaspec u-boot-ingenic repo
• openipc_t31x_kernel.bin and openipc_t31x_rootfs.bin from this post

The camera was booting but the sdcard reader and the wifi wasn’t working.

I thought setting the wlanssid wlanpass via setenv and saveenv would fix the wifi issue but unfortunately didn’t.

So I decided to flash a thingino firmware build from @themactep repo.

As both the sdcard reader and the wifi both weren’t working I actually did this by quickly desoldering the GD25B128C chip and flashing the file directly via CH341A. This worked perfectly fine but the sdcard reader and wifi still weren’t working. I assumed the problems exist due to missing or wrong configured GPIO settings and since @archandanime wrote here that the "SD card detect pin" should be set to 62 the first thing I tried was:

setenv gpio_mmc_cd 62
saveenv

This didn’t fix the sdcard reader problem so I took a closer look at the serial output and saw:

GPIO: gpio_mmc_power: No GPIO env settings provided

Unfortunatly I couldn’t find any information regarding the correct setting for this or even better for all GPIOs on wyze v3. Can anyone give me some information on this?

Here is also the full boot output:

I followed the guide on here to switch to OpenIPC. Booting to the card worked, I heard the audio prompts saying it was flashing then it said it was rebooting. After the camera rebooted it no longers boots. I checked the SD card and the log files are from the first boot, nothing from the second boot to run the script to set the env variables.

Wyze Cam V3 (t31x)

I used https://github.com/gtxaspec/u-boot-ingenic/releases/download/latest/u-boot-t31x.bin for U-Boot and https://github.com/OpenIPC/firmware/releases/download/latest/openipc.t31-nor-ultimate.tgz for the OpenIPC image.

Any thoughts?

v3 only reboots during backup using v0.6.1_t31.zip
