Hi, I wonder if you might advise... 1) what level of coverage is available for an MPC5554 (z500 core) cross-compiler? An appropriate URL would suufice here ;-) 2) which binutils/gcc versions are recommened for this type of venture gcc-3.3.x or gcc-3.4.x? 3) what would the appropriate architecture/target definitiion for building the cross-compiler (e.g. powerpc-eabi)?
