TMDSDOCKH52C1: There are no example projects for TI-RTOS for C2000

Hi Whitney,

Thank you for your response. We have received a feedback from the customer as follows.

The suggested FAQ had very important information that was missing in the manuals I was reading. The manuals instructed to install TI-RTOS through Code Composer App Center, but I could not find TI-RTOS in App Center. I went through the standalone install of TI-RTOS, installed it in Windows, but I was not aware that I had to install it in Code Composer also. That was the missing piece of information, and that's the help I got from the FAQ.

XGConf was still pointing errors when I opened the CFG file. I had to go to "Project Properties > General > Products" and add "C:\ti\tirtos_c2000_2_16_01_14\products\bios_6_45_02_31\packages". It was not clear that this was the path I had to add, nor that I had to fill the Target field with "ti.targets.C28". I got it all by searching through the directories in Windows Explorer and trying to figure out how it all fits together.

After these steps, I can open the CFG file in XGConf and the project doesn't show any more errors until I click the build button. When I do it, the build fails and shows me the following message: can't find the library 'lib/Boot.a28' specified by package ti.catalog.c2800.init. It wasn't found along the path 'C:/ti/controlSUITE/powerSUITE/v_1_07_00_00/packages;C:/ti/tirtos_c2000_2_16_01_14/packages;C:/ti/tirtos_c2000_2_16_01_14/products/tidrivers_c2000_2_16_01_13/packages;C:/ti/tirtos_c2000_2_16_01_14/products/bios_6_45_02_31/packages;C:/ti/tirtos_c2000_2_16_01_14/products/ndk_2_25_00_09/packages;C:/ti/tirtos_c2000_2_16_01_14/products/uia_2_00_05_50/packages;C:/ti/tirtos_c2000_2_16_01_14/products/bios_6_45_02_31/packages/ti/targets/rts2800;C:/ti/xdctools_3_32_00_06_core/packages;..;'.

I'm needing help to fix this last error and would appreciate very much your contribution.

Danilo

Can you clarify if you are trying to create this project for the M3 core (target: ti.targets.arm.elf.M3) or the C28x core (target: ti.targets.C28_float)?

Are these errors in an imported example or a project you've created yourself? If it's the latter, what happens when you try to import and build examples?

Whitney

Hi Whitney,

Here is the response from the customer.

I tried to include TI-RTOS in a new project. I selected an EABI file format for this project, so it matches the projects I'm working on. I searched the directory C:\ti\tirtos_c2000_2_16_01_14\products\bios_6_45_02_31\packages\ti\targets and found the files C28_float.h, C28_float.xdc and C28_float.xs I tried to set the target ti.targets.C28_float in Code Composer > Project Properties > General > Products > targets. It shows me a list of platforms, so I guess this configuration was right so far. I can open the .cfg file with XGConf and use the GUI to configure the TI-RTOS components I'll be using. When I try to build the project, though, it fails with the following message:

fatal error #16000: object files have incompatible formats ("C:\Users\guilh\workspace_v10\MY_PROJECT_TIRTOS_2\Debug\configPkg\package\cfg\MY_PROJECT_TIRTOS_2_p28FP.o28FP" = TI-COFF, "./main_C28.obj" = ELF)

Seems like I should have set the target ti.targets.elf.C28_float so that TI-RTOS code is compatible with my project file format. When I go to the directory C:\ti\tirtos_c2000_2_16_01_14\products\bios_6_45_02_31\packages\ti\targets\elf, though, I can't see the files C28_float.h, C28_float.xdc and C28_float.xs.

Am I correct to assume that TI-RTOS is not available for the elf file format in a F28M35 project? If my assumption is wrong, then how can I configure the target?

Regards,

Danilo

Does it work okay if you create a COFF project instead? It's possible that there is an issue with ELF. I believe BIOS 6.45.02.31 was released before EABI was added to the C28x compiler.

I did confirm that if I created a SYS/BIOS project for the C28x core of the F28M35x using the newest version of SYS/BIOS it didn't give me any format compatibility errors, but it also gave me a linker error that seems like it may be a bug, so you may want to stick with COFF for the F28M35x C28x if you can.

Hi Whitney,

Here is the response of the customer

1. My project is designed for the C28 Core (target: ti.targets.C28_float).

2. All errors were found in a project I created by myself. After importing the example hello that came with TI-RTOS, it compiled and ran. I didn't see any prints in Code Composer Studio "Console" view, though.

Back to my project, I modified it for legacy COFF and selected target ti.targets.C28_float in its properties. I have a blank cfg file. The project was compiling ok before adding TI-RTOS. Now I see multiple errors and warnings regarding memory allocation.

Okay, it looks like you're nearly there. Try a different linker command file that includes the Flash. Maybe see if the one that was used in the "hello" example works in this project.

Or you could get F28M35H52C1_c28.cmd from controlSUITE and make some modifications to it to add .binit and .cio sections (use the "hello" cmd file as a reference on where they should go). You may also need to go into the Boot module settings in your config file and change the Load and Run Segment settings to match actual Flash and RAM block names in your cmd file.

There's a nice guide on linking here if you're new to editing cmd files:
