embedded - Is it possible to run a flash memory dump from a production device inside of an emulator/simulator for offline debugging? -

-

i not sure if right forum, or if better suited in different se sub, though figure appropriate place it.

i wondering if there emulators capable of running flash dump directly targets same architecture on device dumped from? instance, if dump taken device(via jtag) running broadcom mips cpu, , contained entire system(bootloader, firmware, filesystem, nvram, etc.) there mount(or should say, load memory) raw image directly, memory , all, , run it, similar how flash onto different device same chip?

i have been looking different software such ovpsim(which "full system simulator" , qemu, though unsure if can run full dump directly.

can shed light on this, can confusing looking @ everything.

i've run embedded-linux systems under qemu in past, don't far. give emulation of cpu core, enough boot kernel, no emulation of "special sauce" around said cpu (e.g. socs may have timers, gpios, i/o interfaces , whole host of other things).

if dead-set on doing this, i'd grab emulator cpu core , write own. how did depend on emulating - either mess older 8/16/32-bit platforms, or qemu modern-day kit.

be wary of expecting these systems. they're great algorithm development , testing (and lesser extent "black box" automated testing) there's point @ plain need hardware.

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
