sorry for that question, but is there no 64bit double precision support in ccs for msp430??? Perhaps I am blind ;) but I did not find any information about this.
The 64-bit double support varies if you are using COFF or EABI binary formats. Check section 1.3 of the compiler version 4.0.x <README.txt> file typically located at:
I'll move this post to the compiler forum as the experts there may have additional comments regarding this.
Hope this helps,
64-bit double is only available in EABI, which was introduced in compiler version 4.0.0. You need to use --abi=eabi, but you don't need any other options to enable 64-bit double. In COFF ABI, double is 32 bits.
