AM625: about aarch64-none-linux-gnu-gcc

hao teng

Part Number: AM625

Tool/software:

Based on AM625-SDK8.6-rtlinux, I used aarch64 to cross-compile other files but some errors occurred. The operation command process is as follows:

source /home/linux/ti-processor-sdk-linux-rt-am62xx-evm-08.06.00.42/linux-devkit/environment-setup

aarch64-none-linux-gnu-gcc -o codesyscontrol ../main.c MainLinux.c.o -Wl,--whole-archive *.cmp.a -Wl,--no-whole-archive Packages/*/*.3rdp.a -lc -lm -lpthread -ldl -lrt -I../../../Components -I../

How can I resolve these soft connections？

thanks

What are you trying to compile? Codesyscontrol is commercial software received as binary from Codesys.

Hi Pekka

I found that the cross compiler in sdk8.6 does not have some atomic operations such as __aarch64_cas4_acq_tel. I transplanted the ligcc.a library file of linaro11. I am not sure whether it will affect other compilations. Is there a solution supported by ti? To supplement the library of skd cross compiler.

There's currently a large backlog of support cases so it probably won't be until next week before I can look into this.

Regards, Andreas

First recommendation is to use the latest release SDK 10.0. It looks like gcc has moved to version 13.3 from 9.2 that was in SDK 8.6.

Prebuilt binaries come from Arm (https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads ) , back in 8.6 I think they still came from Linaro. I would not mix and match libraries from another release.
