Ingenic Halley2, First problem

I assembled an initial stand for experiments. It has one communication interface UART.
I didn't find information about settings of interface. But analyzing of Phoenix board schematic gave me follow info.
In Halley2 UART2 port is used for debugging purposes. Speed of interface is 115200 8N1.

When I boot stand for the first time I got follow:

I tried to read from flash chip with Uboot commands, but get 0x44 value from different areas.

I decided that it is a problem with incorrect software. Bootloader is for Phoenix board.
