I am trying the calculator example on HDK8250 using Hexagon SDK 3.5.4.

I followed the step by step guide to building, loading and executing the calculator example on Android. Everything seems OK, the example run on CPU passed while on DSP failed with no debug info except for `Error: compute on DSP failed`.

Does anyone meet the same problem? I am pleased to disscus with you.

kona:/vendor/bin # ./calculator 1 1000

---Starting calculator test

---Allocate 4000 bytes from ION heap

---Creating sequence of numbers from 0 to 999

---Compute sum locally

---Sum = 499500

---Success

kona:/vendor/bin # ./calculator 0 1000

---Starting calculator test

---Allocate 4000 bytes from ION heap

---Creating sequence of numbers from 0 to 999

---Compute sum on the DSP

---Error: compute on DSP failed, nErr = 44

---Usage: ./calculator <1/0 run locally> <uint32 size>

Have you generate the testsig for the device ? if not, please follow the steps in sdk.

..../Hexagon_SDK/3.5.1/docs/Tools_Signing.html#TestSigs

if yes, pleaes search key world"fastrpc" in logcat, let me know any error with dsp.

Thanks,

Xiaofeng

I have the same problem as you. Have you solved it

1. Hexagon_SDK version 3.5.4, CPU Qualcomm 8155

2. Compile calculator demo, make tree V=android_Release_aarch64 CDSP_FLAG=1, make tree V=hexagon_Release_dynamic_toolv83_v66 VERBOSE=1

push the compiled file to the android device for execution,

calculator 0 100

---Starting calculator test

---Allocate 400 bytes from ION heap

---Creating sequence of numbers from 0 to 99

---Compute sum on the DSP

---Error: compute on DSP failed, nErr = 44

---Usage: calculator <1/0 run locally>

I checked the source code to AEEStdErr.h file

44 Error codes are defined in the source file as follows:

AEE_EBADHANDLE 44 invalid handle

May I ask if error 44 or above means that my chip does not support dsp function?
