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.
Best regards,
Günter
