RE: MSP430FR5969: Access MSP430 memory above 0x10000 + Energia Imported Sketches (which implies use of unsupported MSPGCC 4.6.3)

Hello Robert,

After installing a clean environment, following your instructions and properly linking all my libs and making the changes needed for my projects to compile, I am having the same error as on my first attempt before your solution (using Energia 17 + GCC 7.3 + CCS 8.2).

I try to compile a smaller code that compiles perfectly on CCS 6.2 + GCC 4.6.3 + Energia 17 and it gives me the same error:

Dwarf Error: Line info data is bigger (0xfffffffc) than the section (0x<varies w/section size>).

Reading the generated .map file, it is trying to generate a HUGE amount of debug data. The size for .debug_info section is much bigger than the whole memory available on chip!

The curious thing is: On the old version that works, this huge amount of debug data also exists on .map file, surely the linker is “being wise enough” to ignore it, I don’t know, I’m not an expert on GCC and LD…

Things I have tried so far: Disable DWARF, uncheck –g option for GCC, replicate the same for linker options. None of these seems to make a difference.

Is there something wrong I am doing or NOT doing that you already know that causes this error?

Thank you so much again for your help!
Mario
