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 .
