Hi, I am using vanilla linux in an AMP setup on freescale P1022 successfully. The needed linux bootargs are: maxcpus=1 mem=448M memmap=64M$0x1C000000 Then there is a linux userspace program and a kernel module (using kernel function mpic_reset_core) to start an application (another OS) on the second core. For communication with the seconds core I use a non-blocking FIFO in a shared RAM section.
