To start with ThreadX, we observed that SMP port is available for Cortex A53 & not available for Cortex R5(SMP). For reference we thought of building SMP RTOS for ARM Cortex A53 by referring this link.
Command Used:-
cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_a53_smp.cmake -GNinja
But it is building for non-SMP Cortex A53 & we observed that there is no .bat file to build SMP Cortex A53. Can you pls let us know whether we are missing something.
Can you pls share the command to build helloworld application (sample_threadx.c) for CortexA53 SMP ThreadX RTOS.
Regards,
Karthik

Hello @Karthik Thangavel Are you referring to this sample file?
threadx/ports_smp/cortex_a53_smp/ac6/example_build/sample_threadx/
Yes i'm referring to that sample_threadx.c which you mentioned.
Ok, thanks for confirming!, Let me check on this! Community SMEs on this topic or our team will review your scenario and circle back at the possible earliest time.

Karthik,
The project has been created with ARM DS, you can use the latest ARM DS to open it, compile it and run it on the simulator.

Hi Andres,
This is Ajay from Xilinx.
Based on above reply, Downloaded ARM-DS and tried to compile Cortex-A53_SMP and facing below issues. Attaching the snapshot of Toolchain Settings. Can you please help me in addressing the issue.

You should be using the armclang compiler. This is what my build output for one of those files looks like when building the Cortex-A53 SMP sample:
armclang.exe --target=aarch64-arm-none-eabi -mcpu=cortex-a53 -I"C:\test\common_smp\inc" -I"C:\test\ports_smp\cortex_a53_smp\ac6\inc" -O0 -g -MD -MP -c -o "GICv3_gicd.o" "../GICv3_gicd.c"
Did you make any changes at all to the project settings?
Hi Scott,
Thanks for the Reply .
In the previous experiment i haven't included the Includes. Now i have included and done changes and still facing the below issue
armclang.exe --target=aarch64-arm-none-eabi -mcpu=cortex-a53+nocrypto -I"C:\Users\threadx-master\common_smp\inc" -I"C:\Users\threadx-master\ports_smp\cortex_a53_smp\ac6\inc" -O0 -g -MD -MP -c -o "GICv3_gicd.o" "../GICv3_gicd.c"

armclang: error: Your installation could be misconfigured or corrupted.
And i observe here that you are compiling for ac6 not for gnu. Any difference in between gnu and ac6 ?
Can you please tell us the required changes to be done in the project settings.
Tool Chain Im using is : ARM Compiler for Embedded 6.
There should be nothing you need to change in the project or files to get it to build when you import the projects into ARM DS. Both the AC6 and GNU projects can be built in ARM DS. If building for GCC, you just need to make sure you have the GNU 8.3.0 tools installed. The error you are getting looks like there is something wrong with your tool install. You may want to reinstall and/or contact ARM about it.
