AFAIK, that linker option isn't implicitly added by LDC.

With -link-internally, LDC uses the builtin LLD; we don't 
recommend it on the cross-compile Wiki for non-Windows targets 
(and a C compiler like clang instead). LLD comes with different 
driver flavors (usually determined by the LLD executable 
filename, e.g., lld-link.exe and ld.lld.exe) with differing CLI; 
plain lld as used for non-Windows targets with -link-internally 
apparently expects `--format=elf` instead of `--oformat`. So 
either use something like `-link-internally -L--format=binary` or 
`-gcc=clang -Xcc=-target -Xcc=armv7em-none-eabi -linker=lld 
-L--oformat -Lbinary`.

I think I should describe the error,
What I want to describe is that the parameter "oformat" cannot be 
passed

我想应该是我描述错误,
我想描述的是"oformat"这个参数无法传递

Yes, sure. But you are specifying that parameter, and it simply doesn't 
exist for that flavour of LLD. It would be different if LDC itself added 
a parameter that then couldn't be found. In that case, it would be a bug 
in LDC. In your case, however, it isn't.

After re-reading the code, I confirmed that the way I passed the 
parameters was incorrect, thanks to David and Kinke for the 
explanation

重读代码后确认了我传递参数方式不正确,感谢David和kinke的说明

Thanks for the answer

ld.lld:
ld.lld --oformat=binary"

ldc2:
