    I have the SOM: MIMX31CSOMCR-C.

    Linux has always reported 64MB of ram but the datasheet states it has 128MB.
    I am currently using Linux 2.6.33.1. But i also tested in 2.6.22.

    Do i need set a boot parameter to get the full 128MB of RAM?

    Thanks

    Just add a mem=128M to the linux boot string.

    From lolo it would be something like
    exec -t -i 1236 "console=ttymxc0 mem=128M noinitrd root=/dev/nfs nfsroot=192.168.100.1:/exports/rfs rw init=/linuxrc ip=dhcp"
