LP-EM-CC1354P10: CC1354 and cc3301, debugging the externally build lwip.a

Part Number: LP-EM-CC1354P10
Other Parts Discussed in Thread: CC3301

Tool/software:

Hi,

I'm starting a project with the cc1354 and the cc3301. It's building and running ok, but now I want to debug it.

The lwip part which was provided by TI is built externally from CCS, with gmake. It ends up in a lwip.a file used during link.

I have two issues with that:

1: When I press F12 on a function defined in lwip.a, it finds the declaration in the .h file. But does not find the function definition in the .c file. 

2: When I step through the execution with the debugger, it does not step inside the function defined in the lwip.a file.

How can I tell CCS where to look for both cases? 

Using CCS20.1.0

Thanks,

Cédric
