Anton Aftakhov got a reaction from Igor in Cubietruck can't boot from sd card after dist-upgradeAfter upgrade I have some problem with boot, but I managed to fix it. USB TTL help this a lot.
Problem was, that symlink 'dtb' was linked to deleted 'dtb-4.11.4-sunxi'. I changed symlink to 'dtb-4.11.5-sunxi' and also renamed 'sun7i-a20-cubietruck.dtb.dpkg-new' to 'sun7i-a20-cubietruck.dtb' (don't know why this folder contains only *.dpkg-new files, maybe because I was trying fix boot without ttl console before).
Now all works ok (maybe until next upgrade), thanks a lot for help.

Most likely your SD card did not survived upgrade. Do you have another (good and quality) SD card, that we can rule out this the most common issue - SD card failure.
It's very very common.
Edit: BTW in last 1-2 years I trashed Samsung EVO 32, Sandisk Ultra 8, Sandisk Extreme PRO and few no name which I use for testing.

You have some old build but still - it should work.
Remove "console=ttyS0,115200" from uboot.cmd and rebuild it.
For verbosity - you only need to create an empty file /boot/.verbose ... even u-boot should put something out on the HDMI screen, at least logo? If we don't have anything on the screen, this could look like u-boot trouble. With serial console we would already solve the problem
Try updating it manually, from some archive one. http://apt.armbian.com/pool/main/l/linux-u-boot-cubietruck-next/

USB OTG can't handle this.
Debugging without serial console is hard ... it cost around 1 USD and will save you a lot of time. Get one, get exactly this one.
One option is to edit /boot/armbianEnv.txt on your SD card and change verbosity to 9 and console to display and boot. Than make a photo with your mobile and attach it here. We still might see something.

We haven't notice any problems - I am running Cubietruck with 4.11.5 for test, I made upgrade to latest kernel 4.11.6 and install to USB drive.
http://sprunge.us/RePh Everything is o.k.
Try to get some verbose logs from serial console - without is hard to find what went wrong.
