I have the following configuration for pmem device :
/* PMEM device */
static struct android_pmem_platform_data omap_pmem_data = {
.name = "pmem",
.start = (120 * SZ_1M),
.size = (8 * SZ_1M),
.no_allocator = 0,
.cached = 0,
};
And while booting the android image, i gave bootargs as mem=120M [.i.e
Total is 128M, Reserving last 8 MB and used as pmem device], but after
booting,
i am continuously getting the following error :
Unhandled fault: external abort on non-linefetch (0x1818) at 0x44a67000
Any clues will be helpful .
Thanks,
Shankar
