TDA4VM: How to debug own app with CCS

Part Number: TDA4VM

Hi expert.

I am trying to debug own app with CCS on MCU1_0 and MCU2_0.

I builided vx_app_tirtos_qnx_mcu2_0.out which is debug mode for MCU2_0.

I am building boot_app_mcu_rtos with debug option for MCU1_0.

I have linking error building boot_app_mcu_rtos code.

Q1. How to fix linking error. I just build to "/mcusw/build" path with "make can_boot_app_mcu_rtos BOARD=j721e_evm SOC=j721e BUILD_PROFILE=debug CORE=mcu1_0 BUILD_OS_TYPE=tirtos"

Q2. How can I load and debug to EVM with CCS.

Is it right? like picture below

Thank you

Hi,

Bit confused. why do you want to build mcu1_0 firmware? Because it runs SciServer. Also why do you want to BootApp in mcusw? Are you using SBL boot flow?

Do you want to include OpenVX on mcu1_0 firmware?

Regards,

Brijesh

Hi,

I just want to know how to debug own app with CCS. I don't care any apps.

Could you recommend apps for debugging test in Ti example and way to build?

I choose apps which are example for each MCU1_0, MCU2_0.

I'd like to debug own app which I can modify and build.

I want to debug MCU1_0 app.

I can modify and build this apps.

Brijesh Jadav said:

Yes, I use bootapp on MUC1_0. I use QNX on A72.

Brijesh Jadav said:

NO, I just use function of boot on MCU1_0.

question

Brijesh Jadav said:

Does this mean I don't modify bootapp? If I make any app on MCU1_0, should I make a code of SciServer?

Thank you.

Hi,

How are you planning to load your application? Are you using SPL or SBL or CCS boot flow? Is your application running on mcu1_0?

Are you using any SciServices in your application? Because then you would have to integrate SciServer with your application running on mcu1_0.

Please refer to below link for more information.

SBL or CCS

No, I have plan to use /mcusw/mcuss_demo/boot_app_mcu_rtos.

I studied document below.

but I don't know how to debug with CCS exactly.

I just confirm a log on DMSC(M3).

I want to load any example code to each MCU1_0, MCU2_0. and set break point.

Thank you

Hi Lee,

BootApp is typically loaded by the SBL, i dont think we have tried loading it using CCS. so could you please try loading it using SBL?

Also BootApp can load the firmwares on the other cores, in this case, since you require mcu2_0, you could create firmware for mcu2_0 and copy it on the SD card and then BootApp can load the firmware.

Can you use below link to understand how to load using BootApp?
