CCS/AM6548: CCS crashes when loading specific OUT-file

Part Number: AM6548
Other Parts Discussed in Thread: SYSBIOS,

Tool/software: Code Composer Studio

Hello,

I followed the steps to create a project for A53 with RTOS:
software-dl.ti.com/.../index_examples_demos.html

When I connect to the first A53 core, and load the .out-file, CCS closes immediatly after the load was complete.

This is reproducable.

Hi,

You have created a target configuration file & connected to the board as explained here:
software-dl.ti.com/.../index_how_to_guides.html

right?

Then it is important to connect to the DMSC_Cortex_M3 first in order for the GEL file to initialize the board properly. Then you can connect to the arm core or cortex R5 core and run your code.

Best Regards,
Yordan

Hi,

Yes, I have created target configuration file & connected as explained.

I do connect first to the DMSC_Cortex_M3. The issue stays the same.

Best regards,
Thomas

Sorry, I misunderstood your question.

Are you running linux or windows on your host PC? If this is linux, can you share the dmesg log immediately after CCS closes?

Best Regards,
Yordan

TI__Guru**** 161600 points

Also which CCS & Processor SDK RTOS version are you using?

0 Thomas Dorsch over 6 years ago in reply to Yordan Kovachev

Expert 2601 points

I run Windows 8 as Host System and use Lubuntu 17.10 as guest system in Vmware.
I use CCS v.8.2 (Version: 8.2.0.00007) on Lubuntu.
SDK RTOS: ti-processor-sdk-rtos-am65xx-evm-05.02.00.10-Linux-x86-Install

Here is my complete dmesg output after CCS crashed:

Thank you for your support!

Ok, sorry but neither of these environments is tested with Processor SDK RTOS 05.02 & CCSv8.2.

The recommended host OS is: Ubuntu 16.04 & Windows 10 (possibly Windows 7). So please transfer to Ubuntu 16.04 as your virtual machine.

Best Regards,
Yordan

All the provided examples for AM65X in Chip Support Library do work. I honestly doubt that a *buntu 17.10 is responsible for that effect.
Is your CCS not crashing when you load the provided out-file to the first A53 core of the AM6548 IDK?

Hi Yordan,

I spend another couple of hours and installed a fresh Ubuntu 16.04.

I installed a fresh CCSv8.2 and followed the instructions at

I installed a fresh Processor SDK RTOS 05.02.00.10.

I created a target configuration to connect succesfully to my AM6548 IDK.

I followed step by step the RTOS A53 Guide:

When I load the outfile onto the first A53 core, CCS immeditaly closes without any message.

Everything behave exactly the same as I observed it with my first Lubuntu setup.

Can you reproduce this on your side?

Hi,

Your project crashes CCS in exactly the same manner on my side. I've notified the CCS team to take a look at this (attaching the crash log for their reference):

HI Yordan,

thank you for confirming the issue and redirecting it.

Is there any possible workaround, to get a RTOS running on the A53 with CCS debugging?

Is there a estimate schedule when this issue could be fixed?

Best Regards and thanks in advance!

Hi Thomas,
Thank you for the executable. Your issue appears related to a known issue with corrupted DWARF information in the generated executable. The Bug ID is: PRSDK-4654. On CCS Windows, the debugger complains that the symbols in the *.out file are corrupted and debug visibility is reduced. On CCS Linux, the debugger (along with the CCS IDE) crashes. I filed an additional bug regarding the crashing on Linux. Tracking ID: CCBT-2401

Thanks
