You would be better of with a $1.99 Serial console from the Pine shop.
Adding to my earlier advice. See what the Serial Console can do for you here : https://www.linuxjournal.com/content/handy-u-boot-trick
Why keep on guessing, if $1.99 will tell you what's going on ?
In the serial console normally, u-boot can be interrupted by hitting Escape during boot. You can then manually check the environment, check what's up and what's not, manually fatload (FAT) or ext2load (EXT2/EXT3) the kernel into memory and execute it with bootm or bootcmd or go (Windows).
But U-boot can be configured to not allow interruption.
Doesn't have to be the Serial Console as sold by Pine. The one from Adafruit for Pi will probably be compatible : https://www.adafruit.com/product/954
