Hi,

I am new on arm code development. I am writing a dummy code on arm A15 core, but am not able to build that on ccs6.2. Please find the attached error which I am getting during the build. What needs to be changed in ccs, can you please tell.

Hi surbhi,

You are getting a linker error where the linker is unable to find the definition to "__stack", which is referenced in the startup_ARMCA15.S file. This symbol is typically defined in the GCC lds file, which I see you are not using. This is the issue. In your project properties, try using the lds file for AM572x (which should be the equivalent of TDA2x).

Thanks

Hi, ki

Thank you for your reply. Now I am able to build my dummy code. But wanted to know a few things:

1) what is the difference between Debug_GNU, Debug_TI & Debug configurations.

2) while loading the .out file on A15 core for the board TDA2x, I am getting an error: Illegal Instruction(core dumped). i am using CCS6.2 version & by default, the compiler version is GNU v4.9.3(Linaro).

for this, I have checked the two earlier post but it's not helping me in my task:

https://e2e.ti.com/support/processors/f/791/p/707997/2609267?tisearch=e2e-sitesearch&keymatch=Illegal%20instruction%20(core%20dumped)#2609267

https://e2e.ti.com/support/tools/ccs/f/81/t/374155

3) can I use inline assembly for ARM A-15 core on ccs for build & debug.

Regards

Surbhi

Those are build configurations. "Debug" is a common configuration, usually the default for most CCS projects. It typically has minimal optimization enabled and full debug symbol generation enabled for a good debug experience. "Debug_GNU" typically refers to a CCS project similar to the standard "Debug" configuration, except that the compiler being used in GCC. "Debug_TI" is similar except that the compiler used is TI. CCS will often rename the "Debug" configuration to the latter two when you switch between TI and GCC compilers.

Since this is an issue unrelated to the original one, please start a new thread for it in the processor forum. One advice you will likely get is to start with an existing example instead of trying to create a new one from scratch. I would recommend the same.

Yes, it should be possible.

Thanks
