can not set --model-large

[zaoshang67dian]

[env:STC8G2K64S4]
platform = intel_mcs51
board = STC8G2K64S4
board_build.f_cpu = 35000000L
build_flags =
--model-large

I get the error:
?ASlink-Warning-Conflicting sdcc options:
"-mmcs51 --model-large" in module "main" and
"-mmcs51 --model-small" in module "_startup".
*** [.pio/build/STC8G2K64S4/firmware.hex] Error 1

what "_startup" is ?

been a long time since I looked at this, but have a look at the SDCC User Guide
section 3.3.6 MCS51 Options

--model-large Generate code for Large model programs, see section Memory Models for more details. If this
option is used all source files in the project have to be compiled with this option. It must also be used
when invoking the linker

also must pass this option to linker
might be -Wl ?

the option of SDCC -Wl i have tried。 but unfortunatly it does not work.
config:
build_flags =
--model-large
-Wl,--model-large
