RAM dumping

---

Does anyone know how to make a complete memory dump (RAM) of the XDA, apart from the m? commands. These commands give a memory, hex, text breakdown. What i'm looking for is a command that get's 32MB of data and stores is as 32MB of DATA (the the invoking and storing the dump is obvious, so no tips on those please, i only want the commands get this raw memory dump).

Regards,
René

I just read up on some of the other stuff in here.
Somebody mentioned the XDA has 32MB of RAM "AND!!!" 32MB of flash ROM.
So, is this true? And if so. Does this mean that the organizer data is held in flash ROM allways? (this would in my opinion not be correct with some of the functions of the XDA, but OK). And if so..... How do i make a raw dump of this memory?

Cheears,
René

Hi,

I'm not aware of a means to dump RAM using the bootloader functions. However I'm considering developing something for it. It shouldn't be too hard with a bootloader patch like we developed to get around 5.17 limitations.

What I'm looking for is info on how data is organized in RAM such as the filesystem. The 32 RAM contains semi persistent data while the ROM contains what is needed to reinitialize the device and system binaries. However, as far as I understand, applications you install additionally and any application data is only stored in RAM. Anyone knows how the filesystem works on the lower level? I'm looking to implement a tool that can read such a RAM dump and make sense outof it.

Ok, so i came up with the idea of using the m? functions for dumping the data (what is the difference between those anyway?), into a huge file (you get 80bytes for each 16 bytes of data, so 160MB for a 32MB model and a hellufa lot of time, say 4 hours at 105200), and than parse these back to the original 32MB, based on the hex dump supplied.

As to your question, for which i'd like the answer myself, about the file system: as it's windows, i hope it will be some form of FAT or NTFS, but what i've seen so far, i'm afraid it's the system MS developed for storing their office documents....

Does anyone know if parts of the data are stored encoded/crunched/ encrypted?

I doubt if its FAT or NTFS, as it needs to handle having its size limitations changed dynamically as the device manages objectstore<->memory changes.

And its all stored compressed.

Well, I recently managed to work out what RAM belongs to the file system, and dump that ram only. And within that RAM I've found some files, and their compressed data, and used the BinaryDecompress calls to decompress it and verify the contents.

However I still can't work out the overall structure that provides the pointers/identifiers to the location of the files, I just happened to find certain files by searching on the filename (which is stored uncompressed BTW).

Has anyone else been trying this?
