Other Parts Discussed in Thread: J721S2XSOMXEVM
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.
