It should be enabled in recent images.
at one of the SCC cores to verify.
It is not enabled. Also, when I typed sccBoot -l, I got this output :NFO: Welcome to sccBoot 1.4.2 (build date Dec 20 2011 - 14:31:57)...INFO: Starting to boot Linux: All cores!INFO: Over-all private memory: 640 MB per CoreINFO: Video buffer size: - 2 MB per CoreINFO: POP-SHM buffer size: - 0 MB per Core (disabled)INFO: Usable private memory: = 638 MB per Core
You can see the POP-SHM buffer size is disabled.
Are you still having problems with 3.1.4scc and POP-SHM?
I check our 1.4.2 beta machine. cat /proc/meminfo | grep POP shows nothing. I was expecting to see a result as in thread:
Also, I have heard you need to use the sccGui to enable, is there a command line equivalent?
sccBoot -l will only enable POP-SHM when enabled in sccGui settings...
Could you please double-check "Settings->Linux boot settings->POP-SHM settings" in sccGui? After enabling a specific amount of shared memory (per core) you should see the memory in Linux (the settings apply for booting with sccBoot and sccGui).
