Sorry for such delay - I was fighting against this problem. Your suggestion was hopeful but it didn't help me. I hope your suggestion will help other people who will face this kind of problem.
I've suddenly noticed that I can see correct symbols of bootloader output on the baud rate 120000 (instead of expected 115200). However, the baud rate of the kernel has to remain 115200. Firstly I thought that it is a manufacturing defect but I've noticed such a thing on the few devices. Also, I've entered into the console mode of the bootloader: the expected baud rate is 115200 (variable baudrate=115200).

I'm using Omega2+ devices. What is the reason for this bug? I'm a little bit confused about how to deal with this problem. I hope for your understanding.
