How to create a project using GCC on TMS570

Other Parts Discussed in Thread: TMS570LC4357, TMS570LS3137, HALCOGEN, UNIFLASH, RM57L843

Hello, guys,

We are using TMS570LC4357 for new project. And there are some old functions on TMS570LS3137, which we want to reuse in new project.

It is easy for us to use Halcogen and CCS to create a new project. But these functions are used GCC to compile, and there are assemble codes included.

So either translate those assemble codes into TI style, or create a new project using GCC.

And we choose the second way. Soon we found code generated from Halcogon, can not be compiled in CCS! Even when Halcogen and CCS both are GCC options!

We feel hard to understand that. Is it not the same way to use GCC or TI compile in CCS or Halcogen? Could you help us out of this mess?

Thank you.

PS,CCS is v8.0, Halcogen is v04.07

Hello,

I am forwarding your post to our HALCoGen development team. Thank you for your patience.

Hi,

Unfortunately the subject matter expert on this is out of office this week, and will return on Monday. Sorry for the wait.

Hello,

Please make sure that you have the GCC for ARM toolset installed within CCS, if not installed already. See below to find this option:

Once you have installed the GCC ARM Compiler tools (and restarted CCS), change your project configurations to choose the newly installed GCC compiler for your project.

You will need to set up the CPU-related "Runtime" settings. See below:

Please also make sure that you add the project's "include" folder as one of the "directories" for the compiler to look for source and header files:

Now you should be able to compile your project without compile errors.

Thank you for your patience.

Regards, Sunil

Thank you Mr Oak. It pass the compile right now. But as I try to upload, something bad happens. No matter via CCS or UNIFLASH, it shows me that:
File: E:/newplatform/purer5_gcc.out Does not match the target endianness, not loaded. Check project build options and target configuration file (ccxml).

And It is be32 as device endianness, I suppose it is the right choice.

See these posts for reference:
e2e.ti.com/.../413871
e2e.ti.com/.../645423

There are some additional steps to do before you can use a library with a BE32 project. All the libraries that come with the GCC tools are compiled for little-endian only.

Thank you, Mr Oak. The GCC project finally run on the board.
There is one thing confusing me. The project, which works, is big-endian. And the device endianess is also set to big-endian. It means that MCU is big-endian in launchpad. But how to change that MCU to little-endian?

TMS570LC4357 is only a big-endian part. The CPU has a way to switch the data endianness by updating the "E" bit of the CPU Program Status Register (CPSR), but this is not recommended. There are also several little-endian parts in the Hercules family. Check out the RM57L843 for example.
