etcher | Flash OS images to SD cards & USB

My question is about Lichee Pi Zero board (based on Allwinner/Sunxi V3s SoC).

Initially I used pre-built Linux image (kernel 4.10.02), it has no built-in Wi-Fi support (for Realtek 8327BS chip), so I downloaded the latest kernel version from here and built it with the default settings.

LCD is ok, Wi-fi looks good too (LED is blinkikng), but I cannot use keyboard anymore - there is no reaction from OS, when I connect something to USB (no message and no input from keyboard).

Hardware is OK and works good with the old Linux image. I have also tried the latest kernel from kernel.org with the same bad result.

Please help to understand the reason. I suppose bad settings, but HID supoort is enabled.

Update 1. I establish connection through UART. As I see, some USB features are detected during boot:

I'm able to load some drivers using insmod also: Unfortunately, Linux still does not recognize any USB Device. I have connected mouse, keyboard, hub, mass storage and got no reaction from OS. It looks like devices do not get power (there is no light from mouse).

Update 2. The best way I have found at the moment is to use buildroot-licheepi-zero. It's very easy to use:

While using the BalenaEtcher software, It somehow killed my USB stick.

Recovery using the Windows' Disk Management Proved to be impossible as any operation done on the said disk would result in an unexpected error thrown by Windows.

Trying to Recover it using Balena's guide to recovering broken devices -which is a guide on using diskpart to clean the device- proved useless as well.

I have been trying to put turtle in tkinter using the canvas feature. I want to be able to make a turtle etcher sketcher thing so that I can control the turtle with arrow keys. I cannot seem to get it to work and don't understand the error it spits out:

NameError: name 'Screen' is not defined

Here is my code:

I cannot use the official Pi camera(s) using either the official Raspberry Pi "Buster" disk image or the Pi disk image provided by Gumstix:

Disk image referenced here--> https://store.gumstix.com/raspberry-pi-cm-fast-flash.html

Note: The Gumstix Pi image would "hang" on the rainbow colored splash screen during boot, using the image above. I am using the "fast flash" board to write the images, and have been able to repeatedly (successfully) install the standard Raspbian OS. FYI I have been using Balena Etcher, and it has worked with my other boards.

Also, I followed the official instructions to add camera support in an attempt to understand what I am doing wrong. vcgencmd initially reported no support or detection in raspbian. I was able to add camera support using the blobs mentioned here (I compliled manually and also used the precompiled variant):

https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-camera.md

Final result:

vcgencmd get_camera : supported=1 detected=0

Lastly, yes the camera is enabled, and I have tested the cam/cable on other systems with no issues. I suspect the pin GPIO settings may be to blame, but based on the information in front of me (for this board) I should not be expecting to manually adjust those params. Thanks for any insight….hopefully this is an I-D-10-T error.
