| Found something odd:
|---------------------
| When jumping pins for FEL mode all systems think the usb device
| is not an allwinner device. In fastboot mode allwinner is shown,
| but shortly after it disconnects.
|
| FEL mode shows:
| Onda (unverified) V972 tablet in flashing mode [02B3]
|
| I flashed the chip and its working in a very basic way. No wifi
| or bluetooth, but at least its working. The root file system is
| not the correct size to build the entire system like an original
| chip. Yocto root file system is 2GB where a stock CHIP has a 4GB
| root file system.
|
| I used: Poky (Yocto Project Reference Distro) 1.8.2 chip Still
| testing. I used Ubuntu 18.0.4 LTS VM running in VirtualBox.

Uhg .. I don't want to stop working on this and get my exercise
(bike ride), there is a wind advisory, and its freaken cold out.
If I don't go now I'll not go today and I'll feel like crap.

------------------------------------------------------------
I had to go back to the VM and reconnect the USB device (the
CHIP), otherwise it would not finish flashing due to a timeout
somewhere in the script > chip-flash-chip.sh
------------------------------------------------------------
I found a post on reddit who sent a boot image to his chip via
UART and U-boot.
This gave me an idea. I have another chip, I can use to copy the
kernel and other boot items off of and attempt to load
everything via UART.
------------------------------------------------------------
Lots to learn here:
------------------
1) Find a CHIP server image.
2) Attempt to flash using server image?
