Testing Hexagon SDK 6.x example on rubikpi3

Hi everyone, I am trying to run the Hexagon SDK 6.x calculator example on rubikpi3, but got the error after executing all these commands.

make tree V=UbuntuARM_Debug_aarch64
make make tree V=hexagon_Debug_dynamic_toolv84_v68

Then I transfer the files UbuntuARM_Debug_aarch64\ship\calculator , UbuntuARM_Debug_aarch64\ship\libcalculator.so to /vendor/bin and hexagon_Debug_toolv87_v69\ship\libcalculator_skel.so to /vendor/lib/rfsa/adsp/ on rubikpi sbc. Error log after running the /vendor/bin//calculator -r 0 -d 3 -n 1000 -U 0 on sbc,

- Starting calculator test on domain 3
src/rpcmem_android.c:38:dummy call to rpcmem_init, rpcmem APIs will be used from libxdsprpc

- allocate 4000 bytes from ION heap
- creating sequence of numbers from 0 to 999
- compute sum on domain 3
- retry attempt unsuccessful. Timing out....

ERROR 0x72: Failed to find max on domain 3

Does anyone know how to fix the domain 3 DSP communication or what might be missing on the board?

Dear customer,
we are currently syncing this issue internally.

Dear customer,
May I inquire which version you are currently using—Android, Linux, or Debian?
Have you attempted to rebuild using the toolchain that matches the SDK?
If the issue persists, please provide a complete dmesg log.

Sorry, I mistakenly mentioned the 6.x SDK, but it’s actually 4.2.3 downloaded from(https://docs.qualcomm.com/bundle/publicresource/topics/80-77512-1/hexagon-dsp-sdk-getting-started.html?product=1601111740010422) Qualcomm, and here is my os info.

Dear customer,
we will check it and feedback soon

Hey guys any update on this?

Dear customer,
Please run the following command:
export LD_LIBRARY_PATH=/usr/lib
When it has completed, proceed with your original operations.

Hi, I tried this too. I used SDK version 6.4.0, following the directions cited in the SDK: 6.4.0.0/docs/examples/calculator/index.html
After building examples/calculator

sudo mkdir -p /usr/lib/rfsa/dsp/sdk
sudo chmod 777 /usr/lib/rfsa/dsp/sdk
Copy libcalculator_skel.so to /usr/lib/rfsa/dsp/sdk
Copy UbuntuARM_ReleaseG_aarch64/ship to /tmp/ship (also copy UbuntuARM_ReleaseG_aarch64/libcdsprpc.so to /tmp/ship)

export EXE_PATH=/tmp/ship
export LD_LIBRARY_PATH=/usr/lib:/tmp/ship
export DSP_LIBRARY_PATH=/usr/lib/rfsa/dsp/sdk

./calculator -r 0 -d 0 -n 1000 -U 0

Starting calculator test

ERROR 0xffffffff: FastRPC Capability API failed. Falling back to signed pd.Unsigned PD is not supported on domain 3.
ERROR 0x1: Calculator example failed

I had to check the SDK documentation to get the ARM-GCC tools installed they are not present by default. I followed the OS build support page’s directions to get them loaded.

Here are my system details (freshly flashed)
Kernel : 6.8.0-1054-qcom
Ubuntu Release: VERSION=“24.04.3 LTS (Noble Numbat)”

BTW I tried every combination of domain/signed/unsigned, but -d 3 is for the CDSP according to the help.

Try using -r 1 it works for me.

Yes -r 1 will work but I wanted to try using the CDSP, so I was using -r 0 which gave errors.

I was missing the fastrpc package, this is the fix:
sudo apt-get install qcom-fastrpc1

This didn’t fix everything so I did the following:

  • Still see the following error:
    • ./calculator -r 0 -d 3ERROR 0xffffffff: FastRPC Capability API failed. Falling back to signed pd.Unsigned PD is not supported on domain 3.
      ERROR 0x1: Calculator example failed
  • Download fastrpc from github and build. I downloaded to my SDK tree: Qualcomm/Hexagon_SDK/6.5.0.0/fastrpc
    • Note: The configure of this is tricky you must install yaml on the rubikpi-target and copy the development headers and libraries to your cross build environment.
      • The cross tools you installed in the SDK need the following:
        • Hexagon_SDK/6.5.0.0/tools/gcc_tools_64/aarch64-none-linux-gnu/lib64
          • libyaml-0.so.2
            libyaml-0.so.2.0.9
            libyaml.a
            libyaml.so
        • Hexagon_SDK/6.5.0.0/tools/gcc_tools_64/aarch64-none-linux-gnu/libc/usr/include
          • yaml.h
  • Once configured and built I did the following:
    • make DESTDIR=/tmp/frpc
    • Carefully copy the install artifacts over to the target
      • Everything in /usr/local is fine
      • For artifacts in /lib/systemd/system I did the following
        • sudo cp cdsprpcd.service orig-cdsprpcd.service
        • copy new cdsprpcd.service to /lib/systemd/system
          • Change this line:
            • ExecStart=/usr/bin/cdsprpcd
            • to
            • ExecStart=/usr/local/bin/cdsprpcd
  • Reboot
    • export DSP_LIBRARY_PATH=/home/ubuntu/calculator/hexagon_Debug_toolv84_v68
    • export LD_LIBRARY_PATH=/usr/local/lib:/home/ubuntu/calculator/UbuntuARM_Debug_aarch64
  • Run:
  • ./calculator -d 3 -r 0 -n 100Starting calculator test
