Part Number: 66AK2H12
Tool/software: Code Composer Studio
Hi there,
I want to get a simple Hello World example working with the 66AK2H12 (K2H EVM), I'm following the guide here: http://processors.wiki.ti.com/index.php/Processor_SDK_Bare_Metal_Examples#ARM_Cortex-A15
1. Start CCS and create a work space for generating the project.
Fine, no problem.
2. Click on File menu option and select New--> CCS Project.
3. Select Target as AM572x -Cortex A15 and GPEVM_AM572x as shown in the image
Fine - I switched the target to my own board's settings
4. Select Cortex A setting in the options below and provide name of the project as "hello_world" and use default Advanced settings for the project. If the Default settings uses "TI ARM compiler 5.x.x" switch to GNU Linaro 4.8.4 (or higher) tool chain for A15 and check the build little endian ELF binary for the A15 core. Under Project templates and examples, select Basic Examples-> Hello World
Click Finish after you are done to allow CCS to auto generate the project from the template Basic Examples-> Hello World.
Here is the problem. I cannot find Basic Examples -> Hello World.
Basic Examples -> Hello World doesn't exist within my CCS install. How can I get this example project? I checked the Resource Explorer, and I can't find a way to download anything called Hello World.
Thanks for any help!
Hello Andre,
The available templates are determined by the device support XML files. The issue sounds related to this old issue:
CCSIDE-2490: Hello world GCC project template should be created for Cortex A15 cores
When looking at the details of this issue, it looks like it was resolved just for AM572x (which happens to be what the guide is showing). In my environment, I can see the template for the A15 of AM572x but not for the A15 of 66AK2H12, which confirms this. I'm not sure if this is by design or oversight. I will need to investigate further

Hi Yordan,
Thanks for the link. Unfortunately, that link still shows me Basic Examples -> Hello World. See my screenshots in my initial post for more info, but I cannot find anything called Basic Examples.
Do you know how I would be able to find that?
Thanks!
In reply to Andre B37:
Andre,
Here is the screen shot of what will work for you. It appears in CCSv8 when you switch from TI ARM compiler to GCC the default endian format is set to big endian and there is no template for big endian due to which the basic project doesn`t show up. If you change the endian format, the issue should be fixed.
Let me know if you are still seeing this issue. For K2H14 device, I would recommend that you set device as 66AK2G12 as that device has same A15 and memory architecture as K2H device so the example should would out of the box. For AM572x, you will need to chnage the .lds file to get the example working.
Regards,
Rahul

Rahul,
Great - I was already in little endian mode, but setting the device to 66AK2G12 was the fix. I was able to access the Hello World example with only a small issue.
I build the example (creating the .out file), I launch the selected target configuration, I then Connect to the Target, I do Run > Load > Load Program and I load the .out file that was built earlier. All that works well.
But then I go to run the program by doing Run > Resume, I briefly see the "Hello World" printout in the Console, and then I get this Unhandled ADP_Stopped exception 0xC013B48
Now, if the "Hello World" message was printed out, then the error must have been at the last line of code in the main function: return 0; The disassembly window also shows me that i'm in a "kill()" function. And stepping through the code, line by line, I don't get any errors until I step past return 0.
Any ideas?
Andre
There are a few things that seem to be broken. To start with CCS install seems to be missing the file startup_ARMC15.S and the project doesn`t have any gcc libratries linked in their.
Can you include the GCC glue code required to configure the core and populate the reset vectors before entering main and also link in the following GCC libraries.
startup_ARMCA15.S
I have not tested this in a while and I am not sure why the glue code file is not in the CCS package. The setup worked with GCC 4.8 and GCC 5.x. ALso, there was a known issue with semihosting (CIO) in CCS so check the release notes to confirm this doesn`t impact your version.
I actually already do have the startup_ARMCA15.s file in my project.
I also see that when I build the project, it builds the startup_ARMCA15.s file and links it, along with the hello.c file, into the .out file. (see bolded section in the Console output below, printed when I 'Build Project')

Also, how do you know that I'm missing linked gcc library? I get no errors when building and linking (as shown above) although the 'Preferences' of my project don't match yours:
What would be the best course of action from here to resolve my error? It doesn't seem to be an issue with missing libraries or with the startup_ARMCA15.s file.
Thanks,
