I think most customers would prefer one project with two build configuration and you can manage the difference in source using configuration level options to exclude files from build or have preprocessor define in the source file to account for RAM and FLASH configurations. However, you should use what is most comfortable for you.

I need to enable the PRU-ICSS (ICSSM0), but SysConfig reports the following errors when I enable it: “Change R5F clock frequency to 400 MHz to configure Core Clock at 200000000 in SysConfig Clock module” “Change R5F clock frequency to 400 MHz to configure IEP Clock at 200000000 in SysConfig Clock module” The PRU-ICSS settings currently show: Core clock: 200 MHz IEP clock: 200 MHz UART clock: 160 MHz However, SysConfig does not provide another selectable value for the PRU Core Clock or IEP Clock; 200 MHz is the only available option. Could you please clarify the following? Is PRU-ICSS operation supported when the R5F clock is configured at 500 MHz? If yes, what Core Clock and IEP Clock values should be used, and how can they be configured in SysConfig? Is this a SysConfig validation issue or a limitation of the AM2611 clock configuration? I have attached a screenshot showing the SysConfig errors and the available PRU-ICSS clock settings.

This clarified the distinction between the default Build Configuration defined by the project and the active Build Configuration stored in the workspace metadata. Based on your explanation, we are now leaning toward a different approach rather than trying to make the RAM/FLASH Build Configuration selection itself more robust. We are considering maintaining two separate CCS projects: a RAM-only project containing a single RAM Build Configuration a FLASH-only project containing a single FLASH Build Configuration This would eliminate the RAM/FLASH Build Configuration selection from normal GUI operation altogether. The source code used by the two projects would be kept synchronized by a separate mechanism where appropriate. We do not necessarily want to require the RAM and FLASH projects to contain exactly the same source code, since there may also be legitimate differences between the two. The F29H85x SDK documentation indicates that some examples provide only a RAM or only a FLASH Build Configuration, so a single-configuration project appears to be a normal supported case. At this point, this approach seems more robust for our use case than maintaining both RAM and FLASH configurations in one project and relying on the active configuration state stored in the workspace. Thank you again for your help and for pointing us to the older discussions.

A function that just contains a call through to another function will be reported as having the same inclusive size as the function it is calling (because this trampoline function has no &#39;exclusive size&#39;). However, the CALL instruction allocates stack space for the return program counter (measured as 8 bytes, only 4 are actually necessary but I think it uses the other 4 to ensure the stack remains 8-byte aligned), and so any function that calls any other functions should have an exclusive size 8 bytes larger than its largest call. This is reporting the maximum stack usage as 88 bytes, but in fact the &#39;inclusive size&#39; of `ClockTree_Init` should be 96, and the &#39;inclusive size&#39; of `main` should be 104. I checked this on an F29H85X-SOM-EVM (using `__asm__ volatile(&quot;MV %0, A15&quot; : &quot;=r&quot; (stackPointer));`) and the stack pointer in `DCC_SetupMeasurement` was 0x20140078, with a stack start of 0x20140010.CCSTUDIO-THEIAF29H85X-SOM-EVMhttps://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/1680979/codecomposer-ubuntu-26-4/6479503Thu, 10 Sep 2026 13:55:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4556f972-4554-4160-a9db-ef2d7f8d45deKiHello, Did you run this required post build step? https://software-dl.ti.com/ccs/esd/documents/users_guide_ccs/ccs_installation.html#post-installation-step-linux-only Note that only CCS 21.x supports Ubuntu 26.04.

Our firmware project is based on the following example from the F29H85x SDK: f29h85x-sdk_26_00_00/examples/driverlib/single_core/system_integration We have developed our application from this example and use multiple Build Configurations, including RAM and FLASH execution. We would like to make the selection of the Active Build Configuration robust and reproducible, particularly when the project is managed in Git and used across multiple development environments. Our concern is that an unintended configuration may remain active due to workspace state or an accidental selection in the GUI. We found the following E2E thread concerning CCS v12.4.0, which appears to be directly relevant: https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/1644144/tms570lc4357-detecting-ccs-active-build-configuration In that thread, the TI response explains that the first element under org.eclipse.cdt.core.settings in .cproject represents the Active Build Configuration, and that changing the order of the elements can change the active configuration. Could you please clarify whether this behavior is also valid for CCS v21, and whether it is a supported mechanism that we can rely on for robust configuration management? Specifically, we would like to understand: - Is the order of elements in .cproject still significant for determining the Active Build Configuration in CCS v21? - If we keep the intended configuration first in the Git-managed .cproject, can we expect it to become active consistently after importing the project into a new workspace? - How does the configuration stored in .cproject interact with workspace-specific state? For example, if a user changes the active configuration in the GUI, which setting takes precedence when the project is reopened or re-imported? - Is modifying the configuration order in .cproject a supported method, or merely an implementation detail that should not be relied upon? - What approach would TI recommend for making the configuration selection robust against accidental GUI operations and stale workspace state? We are not necessarily looking to automate switching or to perform command-line builds. We would like to understand whether the project definition itself can reliably establish the intended configuration. If ordering cannot provide that guarantee, we are also considering maintaining separate RAM-only and FLASH-only project definitions, each containing a single Build Configuration. Would that be a reasonable and supported approach, or is there a better mechanism provided by CCS v21?CCSTUDIO-THEIA
