Tool/software: TI C/C++ Compiler
Hi Support,
my customer is having some troubles with the linker in the version 16.9.4 LTS of the compiler.
Basically, it doesn't like the memory filling option in the linker command file stated by the following line
FLASH (RX) : origin = FLASH_START, length = START(CRCDATA)-FLASH_START, fill = 0xFFFFFFFF
If the filling option is removed, everything runs fine. Can you help me solving the issue?
This is the linking command displayed in the output console.

This does not happen with the version 17.6.0 STS of the compiler (or 15.X:X).

**** Build Finished ****
Can you provide me with some info and tips to solve the issue?
By the way I would also like to use the linker to fill the stack with a specific pattern (say 0xFEFEFEFE). Is it possible?
For your reference, this is the linker command file
