Code compression MPC556

[juninholiveira90]

Hi there. I'm working on a legacy MPC556 microcontroller where I don't have an option to change it. I need any code compressor. Reading MPC555UM, I could find the following at 4.3.1: "Compression is done off line by a special compressor tool, using a fixed vocabulary instruction based algorithm, optmized for the PowerPC instruction set."

I've searched for some compiler or even other tool to compress my C code but I've no idea which one I must use. I saw somebody mentioning about Squeezard compressor but I couldn`t find it to download or even buy it. Is there something I can do to compress my C code ? It can be any tool (compiler with a compression option or compressor software) even in case I need to buy it!

My last option will be to develop by my own but I don't know how tough is that.

Hi, colleague! Have you managed to find any information about the code compression mechanism? Please contact with me [email protected]

Hi @juninholiveira90 

I'm sorry but the tools and documentation for code compression are not available anymore.

Also MPC555/556 are already in End Of Life status, the device is no longer manufactured, so it's not supported anymore.
