Other Parts Discussed in Thread: CCSTUDIO
Tool/software: TI C/C++ Compiler
Hi,
I have compiler and linker issue.
The issue is related with long long variable type and happens only in F2811, but not in F2809.
It is strange that two CPUs have the same core and instruction set.
The compiler is "C2000 Code Generation Tools 4.1.3".
It seems that the linker cannot find LL$$MPY in the library.
Here is the error message.
