That doesn't really help the rest of us, though. > CIO doesn't have exit() though so the RH > simulator *also* has its own syscall interface, just for that call. > If you just want to "exit cleanly" a branch-to-self opcode will also > trigger an exit(0) from the RH simulator. Which is fine, but I'm not interested in interfacing with either the TI or RH simulators. I'm interfacing with other external hardware including LCDs and FAT file systems, and I want to re-use the standard libc interface at the application layer. >> I personally would wish that newlib prefer APIs that are not >> proprietary.

Perfectly understandable that since TI's paying you to do this, they get to choose the default implementation. Like Mark, one of my needs is for input as well as output. For ARM, I can take a binary toolchain from launchpad with a pre-built newlib and substitute a new system interface that meets my requirements. As long as I can do the same thing for the msp430 one, I'll have no issues with the default solution being CIO.
