ARMNN v21.05: Building library using DS-5 toolset #631

Closed supratimc239 closed 2 years ago

supratimc239 commented 2 years ago

Hi,

I have previously built and executed my TF-lite model on ARMNN on Android device. Now I need to port my ARMNN based solution to evaluation board running on Linux.

I was told that the board uses Cortex-A32 and we need to build executable using ARM compiler 6 license from ARM DS-5 tool. While I have ARM compiler 6 license and downloaded already ARM DS IDE 2020.0, I am not sure how to build my model using ARM DS-5 for Cortext-A32 processor.

Any help will be really appreciated.

Kind regards Supratim

Hi,

Could someone please let me know what changes needs to be done in scons/cmake and source code for Compute Library and ARMNN in order to cross compile it for ARM DS-5 for Cortex-A32 processor.

Kind regards Supratim

Have you try to follow the cross compilation guide?: https://arm-software.github.io/armnn/22.02/md__build_guide_cross_compilation.xhtml

or the quick start guide https://arm-software.github.io/armnn/22.02/md_delegate__delegate_quick_start_guide.xhtml

@TeresaARM ,

Thank you for response. I have already used the first link to cross compile. I also now looked into the second link you have shared. But none of them provide information on how to cross compile armnn for ARM DS-5.

Thanks

@TeresaARM https://arm-software.github.io/armnn/22.02/md__build_guide_cross_compilation.xhtml basically cross compiles for arm64. I am trying cross compile ARMNN for armclang. Could you please let me know if there is any link that describe necessary changes?

Thanks

Hi @supratimc239

We don't have a guide specifically for DS-5. Or for compiling for 32bit arm processors at all, the Cortex-A32 predates ArmNN and very few of our optimisations are likely to result in a performance increase. In theory though, if you did want to try and compile ArmNN for your board, you could use the cross compilation guide @TeresaARM linked above, but replace the instances of CXX=aarch64-linux-gnu-g++ CC=aarch64-linux-gnu-gcc with your version of armclang which is included with DS-5. This is likely to run into problems with dependencies and libraries so I make no guarantees.

Sorry for the lack of support in this case. Regards, David
