aarch64-linux-gnu-gcc vs aarch64-poky-linux for IMX8M Mini based custom hardware

sreedhar_appala — Wed, 25 Mar 2020 00:12:58 GMT

Hi,

We are working with IMX8M Mini based custom hardware.

when we are working with IMX8M Mini EVK, we build the toolchain and

for cross compiling and building our test application we sourced the following tools.

$ . /opt/fsl-imx-xwayland/4.9.51-mx8-ga/environment-setup-aarch64-poky-linux

our build is fine.

My question is IMX8M Mini is ARMv8 - 64bit arcchitecture.

We believe we can cross-compile and build our test application using aarch64-linux-gnu-gcc also.

we believe efficiency of the output file may vary.

considering the developmet hardware is IMX8M Mini based platform. Could you please suggest and recommend which cross compiler to use and why.

Thanks in Advance,

Sreedhar

Hello,

Recent Linux BSP L4.19.35 supports the GCC 8.3 toolchain.

https://www.nxp.com/webapp/Download?colCode=L4.19.35_1.1.0_LINUX_DOCS

Generally it is possible to use different toolchains for simple applications, but using

the SDK approach is more preferable, since it provides proper environment for development.

Have a great day,

Yuri

Hi Yuri,

Thank you for the quick reply and details.

We are using linaro toolchain "gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu" earlier.

Do you have any benchmark details for the different tool chains atleast for the linaro based toolchains and SDK based environment.

My question is very generic, kindly let me know.

Thank you, Sreedhar

Hello, sreedhar.appalayagari@sony.com

I've not found internal comparison considerations about the toolchains, sorry :-(

Regards,

Yuri.

Hi @sreedhar_appala @Yuri I am also working on iMX8M embedded board.

I have compiled the image and and cross compiling tool-chain for the same successfully using the bitbake meta-toolchain which has generated fsl-imx-xwayland-glibc-x86_64-meta-toolchain-aarch64-toolchain-4.14-sumo.sh to use for cross-compiling .c based project.

But I am not aware of how I can use it in makefile based project. Here is my simple make file which is generating .exe file for me.

# Compiler CC = gcc # Path to static library source (testlib.a) LDFLAGS=-L../../testLIB/lib LIBS=-lpthread # C compiler flags (-c -Wall) CFLAGS= -g -Wall ifeq ($(OS),Windows_NT) RM=cmd \/C del else RM=rm -f endif # Source files SRCS = $(wildcard *.c) # Object Files OBJS = $(SRCS:.c=.o) # Executable File EXECUTABLE = targetImage.exe .PHONY: depend clean all: myprog myprog: $(OBJS) $(CC) $(CFLAGS) -o $(EXECUTABLE) $^ $(LDFLAGS) $(LIBS) # Clean .o and .exe files form the respective directories # make clean clean: $(RM) $(OBJS) $(EXECUTABLE) # Read source files and create dependencies depend: $(SRCS) makedepend $(INCLUDES) $^

But now I want to update it to generate .exe which can be run on yocto board. Can you please guide my what I can I do to achieve the same Or if you can share me some examples or documents which I can refer to understand the same would be great help. Thanks in advance to both of you. Please let me know if I missed to add any other required info. I am very new to this and I am stuck with this step.

can you please share how to install "environment-setup-aarch64-poky-linux" toolchain for iMX 8M mini
