Try to borrow a USB-TTL Serial from a friend ...

You should get equipped with a USB-TTL Serial dongle and attach it to the serial debug port of the OPiOne, you will then see all the logs at boot time and we will be able to figure out with you.
 

Assuming you have "dtc" installed (and keep a backup of the original /boot/dtb/sun8i-h2-plus-orangepi-zero.dtb :
dtc -I dtb -O dts -o sun8i-h2plus-orangepi-zero.dts-4.11.12 /boot/dtb/sun8i-h2-plus-orangepi-zero.dtb Edit the DTS with "nano sun8i-h2plus-orangepi-zero.dts-4.11.12" and add 'ethernet0 = "/soc/ethernet@1c30000"; ' in the "aliases" section.
Then, recompile the DTB :
dtc -I dts -O dtb -o /boot/dtb/sun8i-h2-plus-orangepi-zero.dtb sun8i-h2plus-orangepi-zero.dts-4.11.12

If you wish to update applications without updating u-boot/kernel due to problems faced, you can use "apt-mark" to disable some unwanted updates.
 

How do you use "dd" for that ?
You can not use "dd" directly with /dev/spidevX-X, since it doesn't handle SPIFlash commands ...
Either you use "flashrom" utility to write whole image or use python pyspiflash library and manage sector/page erase/read/write yourself.
Don't expect been able to use it as filesystem, first because MTD partition kernel driver is probably not in Legacy builds, and second because those SPIFlash are pretty small.
Those SPIFlash are ususally present to place U-Boot bootloader to allow booting from other devices such USB Storage or Network share.
 

Thanks, @balbes150 !
I so used to play with Mainline, that I feel like a newbie and playing with Legacy ...
The "modprobe dhd" worked.

After installing the above python library, simply run this python script :

And there is one small change in description - Armbian is now noted as "supported OS"

Obviously, I've missed the clearly visible 8198FTV, I was searching for the AP6212A

If you have an USB-TTL Serial dongle attached, it would be easier to figure out since you will see all the booting phase logs.
 

Isn't that reversed : it is the lower that was working but not the upper ...
This is now fixed with this commit : https://github.com/armbian/build/commit/cc4e1ccc8e236b0a3eadabaa9c7b74af43065512

The first one ! u-boot AND rootfs from eMMC.
( the second means u-boot only on eMMC and rootfs on SATA/USB )
 

Did you use either internal PullUp or external PullUp to 3.3V ?
If not, the wire is acting as an antenna with random states.
 

There is no real PMIC on OPiZero, this means the power supply still plugged on the SoC, even after shutdown command.
 

The way you are reading the serial port is ugly since you try to read(1000) without even checking if there is something to read, and yes 0.1ms is waste of time, especially if serial is empty, you should make it longer.
You should is serial.inWaiting() > 0 to check if at least one char has come in...
 

Although I didn't raad the whole thread and links, why are you trying to do ssh on port 2222 while standard port is 22 ?

Leave the PA13 as SPI_CS, and choose any other free GPIO for the IRQ, could be the original PA7.

PA13 : single pin cannot be IRQ and SPI_CS at the same time ...

Using "truncate" with the "endsect" number shown by fdisk after gparted shrinking.
Here is the sequence :
sudo modprobe loop sudo losetup -f sudo losetup /dev/loop0 myimage.img sudo partprobe /dev/loop0 sudo gparted /dev/loop0 sudo losetup -d /dev/loop0 fdisk -l myimage.img sudo truncate --size=$[(endsect+1)*512] myimage.img  

You will need to ask that to Raspberry forum, because here, in the Armbian forum, there is NO support for Raspberries.
 

Good luck ! This part isn't easy to find in bulk, none on eBay or AliExpress ...
 
EDIT : Oh ! instead of searching PST73118BETV like schematic says, TI has some TPS73118, some on eBay.
 
Lucky Guy ! I found that MCP1824 on AliExpress in abundance, and it seems to be pin compatible, some sellers offer them at $4 for lot of 10.

BTW, Raspbian != Armbian ...

To my knowledge, HDMI Output cannot be used as input...
 

Yes ! Your second card doesn't have u-boot !
You should do a 'dd' between cards but only the first 1M.
Then, with 'fdisk' on the new card, delete partition and re-create it to match size of the card, followed with 'mkfs.ext4' for reformatting.
After that, you can tar or rsync the rootfs filesystem.
