Hello Everyone,
I am trying to boot android in our Custom board. This board is very
similar to that of OMAP3EVM from Mistral.
But when I attempt to boot I am getting a Kernel panic while executing
init ie init=/init. I am able to boot the Kernel when I change init
the bootargs ie init=/system/bin/sh, but after this when I attempt to
run init, I am getting a segmentation fault. On analyzing this through
strace command I have observed that it is not able to open the node /
dev/ashmem but the same has been enabled in the Kernel configuration.
# strace init
