Use of malloc

[tba10596]

in embedded_cli setup, malloc is used because it "guarantees alignment". Is there another way to do this so that heap can be set to zero?

I think I don't understand question. If you want to set your buffer to zero, you can use memset and pass 0. But that's not needed, since it's already done:

If you can't use malloc, you can just declare static buffer of memory and pass it to cli.
