Part Number: TDA4AL-Q1
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

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.
