TDA4AH-Q1: TDA4A - CCS Setup and Example flash and debug using CCS

Hi Aryan,

Which example you want to debug from CCS?

We need to have CCS initialisation script before loading and running any example from R5 core.

Following link explains how to use CCS initialisation script, Please follow the steps given in the section 7.3 Debugging without HLOS running on A72 (RTOS-only / baremetal).

i am uisng CSL Uart test Example using that example i am building and after that i am connecting first cortex M_4F0 and some gel command is running after that i am initializing under script section 

Hi Aryan,

Steps to run example from CCS:

1. Please make sure you have proper target configuration file defined for J784S4EVM.

2. Add initialisation script file for CORTEX_M4F_0 as given in the above shared link.

3. After successful launch of the launch.js file, Load and run the binary which gives O/P on the respected console (MCU).

Note: You can build any UART example from PDK on mcu1_0 and observe the O/P message on the console.

Build UART example by providing the following command from PDK_*version*/packages\ti\build/

make -s UART_Baremetal_TestApp CORE=mcu1_0 BOARD=j784s4_evm

Load and run the binary on MCU1_0 core to observe the log on console.

Anil

Hi Anil , 
After successful launch of the launch.js file, Load and run the binary which gives O/P on the respected console (MCU). - i am facing problem here 

js:> loadJSFile("C:/ti/ti-processor-sdk-rtos-j784s4-evm-11_02_01_03/pdk
_j784s4_11_02_01_08/packages/ti/drv/sciclient/tools/ccsLoadDmsc/j784s4/
launch.js")
Uncaught ReferenceError: loadJSFile is not defined
js:>
this error is showing only .
please help me . is there any other way to do . 

i am using CSS thia (new version )  is this create any problem . 
thanks

Hi Aryan,

CCS Version 20.x will not support loading loadJS from CCS console.

You can use CCS Version 12.8.1.

Please refer the following E2E Thread that explains which CCS version to be used.

 [FAQ] TDA4VM: Is CCS 20.x or Theia supported on TDAx devices?

Anil

hi anil ,
should i download again lower version or is there any way we can do it in this version only .

thanks

Hi Aryan,

It is recommended to use older CCS version to debug via CCS for J7 Processors. 

But how you are connecting via CCS to load and run the application, Is the code is hanging from sciClient initialisation in Board_init API?

- Need to comment the "Board_sysInit()" from Board_init API from board_init.c file

- Need to add only "boardCfg = BOARD_INIT_PINMUX_CONFIG" in Board_initUART api (remove BOARD_INIT_MODULE_CLOCK)

Build the board library and then UART application by giving following commands from packages/ti/build folder.

gmake -s board CORE=mcu1_0 BOARD=j784s4_evm

gmake -s UART_Baremetal_TestApp CORE=mcu1_0 BOARD=j784s4_evm

You can connect to MCU1_0 core by following same steps as you mentioned in the previous reply.

(Connecting to M4F_0 core, then run the script J7_LPDDR4_Config_Dual_DDR_Gran_128B_4266MTs. and after this you can connect to MCU1_0 core to load and run the binary)

i checked it with older version CSL_uart_Test example is working . tell me one thing if i want to run that example in mcu2_0,MAIN_Cortex_R5_0_0 what changes i have to do in code or what is the flow . first i have to connect MCU_0 and run and then jump to connect MAIN_Cortex_R5_0_0 and then flash the build code for MCU2_0 and then run . Can you please tell me .

Thanks

Hi Aryan,

There is not support for MAIN_Cortex_R5_0_0 core(mcu2_0) for csl_uart_test_app in PDK.

Can you try with driver example "UART_Baremetal_TestApp" which is supported on mcu2_0(MAIN_Cortex_R5_0_0) core.

Steps to run the example:

- Whatever the steps you followed for running csl_uart_test_app on MCU1_0 core is correct,( Launching the launch.js file and then run sciserver_testapp_main by clicking resume button from the ccs on MCU1_0 core after launching the launch.js file) 

- Connect to MAIN_Cortex_R5_0_0 core and load the UART_Baremetal_TestApp binary built for MCU2_0 core.

Regards,

Anil 

Hi Anil , 
Correct me if i am wrong 
whenever i have to debug the any main cortex . MCU1_0 will be running state correct . 
thanks 
Aryan vats 

Hi Aryan,

Yes, MCU1_0 should be in running state:

After launching launch.js file successfully from CCS, Click on "Resume F8" button to run the SciServier application.

Then connect to MAIN_Cortex_R5_0_0 core, load & run the binary.

Hi Anil, 
I am trying to flash and debug led_Blink_test for MCU2_0 but uart is working but LED is not blinking . Can you please tell me is there any changes i have to do for LED blink test or  should i use MCU1_0 test . 
Also i want to implement RTOS application how is the flow for checking a example code for RTOS .

Thanks and Regard

Hi Aryan,

UART test is working on MCU2_0 without any modifications in CCS older vesrion?

If yes, what logs you are getting while running LED application on MCU2_0?

Regards,

Anil

Hi Anil,

For MCU2_0, I have made some changes to the UART peripheral and configured it to use the Main UART.

I also have a question regarding running the LED application on MCU1_0. If we are using the User LED, I understand that the User LED is connected through an I2C expander. However, I could not find any code related to the I2C peripheral implementation.

Could you please confirm how the User LED is expected to be controlled in the MCU1_0 LED application?

Regards,
Aryan

Hi Aryan,

Can you please exaplin which example you are using for LED application on MCU1_0 core?

Regards,

Anil
