A simple program write in C that use mailbox for passing messages between the two microblaze. I made many simple application but they don't work.
I want a simpe array char that Microblaze_0 write in mailbox and Microblaze_1 read this array.
I hope to be clear.
Thanks

Still not sure.

You want a program written in C for this. Do you intend to have this program running on the microblaze?

I made many simple application but they don't work.

Well, to help other help you ... it might be useful if you include some of those applications. WHat didn't work about them.

And with "mailbox" I take it you mean you have a buffer on both sides to write messages to and from. And then some flag to read out message status.

Well, there you have it. Implement a buffer + status flags on both sides, and functions that access those. Maybe put a FIFO between the two microblazes? Or do they access shared memory? All details that could be useful for someone to guess what it is what you are trying to do...
