Compiling and Linking Host Code for Bare-Metal - 2024.1 English

To build the PS application for the bare-metal flow, use the platform generated in the prior step. You need the PS application (main.cpp), and the bare-metal AI Engine control file (aie_control.cpp), which is created by the AI Engine compiler and can be found in the ./Work/ps/c_rts folder.

Compile the main.cpp file using the following command:

aarch64-none-elf-gcc -I.. -I. -I../src \
-I./vck190_baremetal/export/vck190_baremetal/sw/vck190_baremetal/standalone_domain/bspinclude/include \
-g -c -std=c++17 -o main.o main.cpp

where, vck190_baremetal is the user-defined platform name.

Compile the aie_control.cpp file using the following command:

aarch64-none-elf-gcc -I.. -I. -I../src \
-I./vck190_baremetal/export/vck190_baremetal/sw/vck190_baremetal/standalone_domain/bspinclude/include \
-g -c -std=c++17 -o aie_control.o ../Work/ps/c_rts/aie_control.cpp

Link the PS application using the two compiled object files:

aarch64-none-elf-gcc main.o aie_control.o -g -mcpu=cortex-a72 -Wl,-T -Wl,./lscript.ld \

-L./vck190_baremetal/export/vck190_baremetal/sw/vck190_baremetal/standalone_domain/bsplib/lib  \
-ladf_api -Wl,--start-group,-lxil,-lgcc,-lc,-lstdc++,--end-group -o main.elf
