TDA4AL-Q1: MCUSS Demo Application : CAN Profiling Application operate in Tx only or External Loopback and Polling mode or interrupt mode all failure.

Hi, Ti's experts:

SDK: ti-processor-sdk-rtos-j721s2-evm-08_06_01_03, ti-processor-sdk-linux-j721s2-evm-08_06_01_02

Development board: J721S2XSOMXEVM

I am study the MCUSS Demo Application : CAN Profiling Application, and do the follow six test, please check it and help to fix the Questions(Q1, Q2, Q3, Q4).

Test 1. operate in internal loop-back and interrupt mode by default  : Run OK.

step1: build

hduser@J721S2:~/ti-processor-sdk-rtos-j721s2-evm-08_06_01_03/mcusw/build$ sudo make can_profile_app BOARD=j721s2_evm SOC=j721s2 BUILD_PROFILE=release CORE=mcu1_0 BUILD_OS_TYPE=freertos -sj

step2: use the CCS to load and run the can_profile_app_freertos_mcu1_0_release.xer5f on MCU_Cortex_R5_0.

Step3: Read the UART log, and we can find it works ok.

Hi Shui, 

Are you able to build these demos for MCU_Cortex_R5_1 (mcu1_1) and run them again? MCU_Cortex_R5_0 should host the SCI_Server which you need to run after your launch.js script.

Hi，Daviel Almonte

Thanks for your suggestion.

About your suggestion "build these demos for MCU_Cortex_R5_1 (mcu1_1) and run them again":

I use the command "make can_profile_app BOARD=j721s2_evm SOC=j721s2 BUILD_PROFILE=release CORE=mcu1_1 BUILD_OS_TYPE=freertos -sj" to build, but it could not generate any Image or *.xer5f files, so I could not do the test. If the building command is wrong to build demos for MCU_Cortex_R5_1 (mcu1_1), please share me the right command, thank you.

BTW, 

I use the similar command "make can_profile_app BOARD=j721s2_evm SOC=j721s2 BUILD_PROFILE=release CORE=mcu1_0 BUILD_OS_TYPE=freertos -sj" to build, it could generate the Image and *.xer5f files. And I use the "can_profile_app_freertos_mcu1_0_release.xer5f" in CCS to debug and run.

 

Regards

Shuai Feng

hi, Shine

Thanks for your help, I have got the suggestion from E2E enginer Tarun Mukesh, and have given a feedback.

The follow link seems meet the same question,but no detail solution, please check it and share me the detail solution.
