Srikrishna, glad you enjoyed it. Thanks for jumping into the chat with a great question again. Saving a coredump will have to happen before the device reboots, so the state of the system can be saved. Therefore, collecting data for a coredump will need to happen as part of the handling of a fault, so you would need to write your own fault handler to do this collection. You can take a look at our fault handler here. Notice that we call memfault_platform_coredump_get_regions() in this handler, which is a function that will collect data for the coredump. As far as where to put it once it has been collected, yes, flash is one option. You could also store it in the "noinit" region of RAM, which persists across boots. You can take a look at our RAM-backed coredump here which does exactly that! Note however that space is more limited when using that region so only a few items could be collected like the active stack, PC, and LR. But, it is typically faster to get up and running with when first trying out coredump collection.
