Setup Help with Hello World with TMDSSK3358

Dan Williams88

Other Parts Discussed in Thread: TMDSSK3358, AM3358

We have the AM335x Starter Kit (TMDSSK3358). I installed Code Composer Studio (CCS) version 6.0.1.00040 on my Windows 7 64-bit OS development PC. I am attempting to compile and run the Hello World example that comes with CCS. Here is what I have done so far:

1. I have the Linux SSD card in the board and the OS boots up. I can see the icons on the touch screen.

2. I attached the USB cable that comes with the kit. I can see the board as a drive via Windows Explorer and copy files to the board.

3. I have also logged into the board via PuTTY on the COM5 port. I can issue "ls", "cd", and other normal Linux terminal commands.

4. I compiled the Hello World "C" application that comes with CCS.

5. I download this HelloWorld.out file to the board using Windows Explorer.

6. I run "HelloWorld.out" via PuTTY and I get the error, "Illegal instruction".

My guess is that I failed to pick the correct "Device Variant" in CCS when I created the workspace. I think this in turn has the wrong compiler and linker flags set when I kick off a build in CCS? So my question is, which device variant do I pick? I tried "SK_AM3358 [Cortex A]" and "SK_AM3358 [Cortex M]". Both have the same "Illegal instruction" error.

Also, which Connection type do I pick so I can download the executable to the board and run it via CCS? Is it "Texas Instruments XDS100v2 USB Emulator"? I would rather compile, download, and run the executable via CCS rather than manually copying the file using Windows Explorer and running the HelloWorld.out exe via PuTTY.

Dan,

I think your correct. You do have to identify the correct GCC compiler for CCS. See the instructions to create/build HelloWorld here: http://processors.wiki.ti.com/index.php/Sitara_Linux_SDK_How_To_Guides

as long as you point to the proper cross-compiler that we include in the SDK or one of your choice.

The Cortex A8 is ARMv7. Our path : <SDK INSTALL DIR>/linux-devkit/sysroot/i686-arago-linux/usr/bin

A way you can identify what target you built it for : at console : 'readelf -a -W executable_file' or 'file executable_file'.

==========================================================

To setup CCS + JTAG to talk to AM335x you do need external XDSxxx emulator. From your post, looks like you have XDS100v2. Then yes, choose 'target = AM335x' and 'emulator = XDS100v2'.

To build and download using CCS - this would assume Linux is not running.

If you want to have linux running with the ability to download or copy newly built execuables, then the typical path is to use 'gdb/ddd' to setup live connection between CCS and target. The other is using RSE - Remote System Explorer. Both of which are integrated into CCS.

See these links for tutorial walkthroughs.

Hope this helps,

Rafael,

Yes. I want to develop a Linux application and run it on the AM335x starter kit board. And the links are to how you configure CCS version 5 for Ubuntu Linux as the host development PC.

I need to know how to compile CCS version 6 running on Windows 7. More specifically, what is the Device Variant do I pick?

It appears from the forum post you linked to, John Boyd2 did not have any luck either.

By the way, thank you all for your quick replies! I appreciate it.

Here is the output from, "file HelloWorld.out":

root@am335x-evm:/media/mmcblk0p1# file HelloWorld2.out
HelloWorld2.out: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped

Marc,

Here is a screen shot of what I have selected as the Device Variant. Is the "SK_AM3358 [Cortex A]" correct for the TMDSSK3358 (AM335x Starter Kit)? Again, I have the Linux SSD card so Linux is booted up and running on the starter kit board. And I would like to compile a Linux Hello World app to run on the starter kit board. And my development PC is Windows 7.

If you want to develop a Linux application, as opposed to a bare-metal application, then you need to use a different compiler to the TI or GNU ARM compilers which come with CCS.

See the last post from how to setup CCS v6 to cross compile on WIN 8 for BeagleBone Black running latest Angstrom image for what should be a suitable gcc-linaro-aarch64-linux-gnu-4.9-2014.09-20140911 compiler to cross compile Linux applications in Windows
