OpenOCD absolute beginner + EK-LM3S6965 + Eclipse + FreeRTOS

Development Boards MicroMod
1

Hi,

I’m trying to develop/debug a project using FreeRTOS 6.1.1 on a LuminaryMicro EK-LM3S6965 evaluation board, under Win32.

I use FreeRTOS6.1.1 + Eclipse Helios + CodeSourcery G++ Lite for Arm Ver. 4.5.1 + OpenOCD 0.4.0

I can build and link the .bin file but… I have problems to debug with the OpenOCD (programmer and server not working).

No connection with the target and/or error messages.

I tried several .cfg files, with the result to increase my mental mess and to loose the faith in the Lord.

Any suggestion about the OpenOCD and the .cfg files to use?

I’m getting insane, please help me.

Thank you

Antonio

Hello Antonio,

might be we could help you better, if you answer the following questions:

Which debug adapter do you use?

How do you start OpenOCD (with which commands)?

What are the error messages OpenOCD produce?

best regards!

Stefan

Thank you Stefan,

I try to answer to your questions and to explain what happens.

I don’t use any debug adapter, just the EK-LM3S6965 board connected via USB link.

The USB/microcontroller interface is made using the FTDI FT2232 chip.

Today I started again from scratch reinstalling the whole environment and using the OpenOCD and the .cfg files delivered with the FreeRTOS 6.1.1 distribution.

When I start the OpenOCD to program the RTOSDemo.bin using the Eclipse GUI, I obtain the following messages:

Does it mean that the programming operation has been correctly performed? Why that plenty of warnings?

Then, when I start the OpenOCD server:

– Info: openocd.c:92 main(): Open On-Chip Debugger (2007-08-17 11:00 CEST)

with the program correctly stopped to main()

but when I start the debugging I get the following messages:

Sometimes I get the message saying that there are no “launches available”.

Hello,

I also have the same problem. How can I solve it ? Someone have the solutions?

Does it mean that the programming operation has been correctly performed? Why that plenty of warnings?

yes the flash operation succeeded, you can verify by using:

verify_image ./RTOSDemo/RTOSDemo.bin 0

You are using an old version of OpenOCD, the warnings have been removed in newer versions.

I am guessing you still have the previous instance of OpenOCD running.

OpenOCD is a daemon, and will stay running until told to quite via the shutdown cmd (or ctrl-c).

OpenOCD config scripts can change so i would always recommend you use the ones provided, eg. 
source [find board/ek-lm3s6965.cfg]

Also get a newer version of OpenOCD the one above is 5 years old.
