Another way:
Set .mybss as "@nobits!".

Code:

__attribute__((section(".mybss, \"aw\", @nobits!")))

If you want only copy section, you can use -j option
-j --only-section <name> Only copy section <name> into the output

Only output specific section .section1 from .adx file to .bin file.

Only section command:
nds32le-elf-objcopy -S -O binary -j .section1 "cut-section-remove.adx" output/only-section1.bin

The output "only-section1.bin" will be 0x000004d2 = 1234.
