Missing ResetISR when importing Energia sketch

I get this message:

c:/ti/ccsv6/tools/compiler/gcc-arm-none-eabi-4_8-2014q3/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld.exe: warning: cannot find entry symbol ResetISR; defaulting to 00000000

Which version of Energia are you using? And which target device/board do you choose during import? 

I can build the Blink example for tm4c123 without any errors. As part of the build it links in a core library which resolves symbol definition for ResetISR.

Can you provide more details about the device you are working with, and the full output of the CCS build console?

Hello AartiG. Thank you for your response. I am using the TM4C123G launchpad, and Energia 0101E0015. I'll provide the full output of the build console this afternoon once I come home.

Also, trying other examples (Servo, for instance), it does not recognize some of the interrupt calls. But let's take one step at a time, because they may be related.

Thanks again,

Pedro

Hello Aartig,

It may very well be that it is missing a core library, but I have no clue which one it would be. The "Import Energia Libraries" doesn't have an obvious option.

Here is the output from the build:

Thanks again for your help.

When I import Blink example, it also imports lptm4c1230c3pm_core project. This project has the source file startup_gcc.c which defines ResetISR.
Do you see this project in your workspace?

Since lptm4c1230c3pm_core is set up as a dependency for Blink, it will get built first when you build Blink and generate the appropriate library to be passed to the linker. Your command line appears correct and same as mine (you can see the -l"lptm4c1230c3pm_core" passed to the linker), but the key is whether the library exists in the folder C:/Users/pjr/workspace_v6_1/lptm4c1230c3pm_core/Debug or not. That library should get created when the lptm4c1230c3pm_core project is built.

Again, I really appreciate your help

I think you are on the right track. There is a project with the name lptm4c1230c3pm_core in my workspace. there is also a library (assuming the .a indicates a library under the C:/Users/pjr/workspace_v6_1/lptm4c1230c3pm_core/Debug directory. However, when I tried do re-import Blink (after deleting both the Blink AND lptm4c1230c3pm_core projects (deleting the files as well), I get the following error:
