I working on some programing project, and at the time i looking for an information about of : how the GRUB2 using the file /boot/grub/grubenv ?
In particulary how the GRUB find the start LBA of the file before loading content of it ?
TIA.
GRUB use file system drivers to performs working on partition as usual.
I want to upgrade my systems in the field using the uboot FIT images.
My system is a custom firmware, booted by uboot. So far the FIT filesystem works very good. It provides a shasum verified upload. I am using uboot scripts to update stuff on the target.
One intriguing type defined in uboot docs is type "filesystem". The actual content could be several things, like maybe tar'ed bunch of files, or an actual collection of separate individual files in one chunk in the FIT.
In another FIT question, Tom Rini implied that a filesystem is really just a binary blob. What goes into it is my problem and that uboot could then just mmc write ... or usb write ... to create the new filesystem on some partition. Is this really the case?
How can I build a filesystem (say FAT), on a host build computer for packaging with FIT?
Thanks, Steve
The creation of a filesystem image will depend on the filesystem itself. In many cases, build systems such as OpenEmbedded or buildroot can help you here as they will create the images for you.
Is it possible to read android mobile device RAM content.
I am able to see passwords in RAM using HxD editor.
Is it possible to view the password using any tool on device?
Just taking a heap dump of ram with android studio dude.
You take the heap dump and seek the package name you are looking for and probably you can find passwords and whatever is in RAM.
What is the difference between a QNX "Flash filesystem image" and a "OS image"?
I've got an old PC104(x86) unit that works solely with a CompactFlash card drive and now I'm wondering if I need the first or the second one to put on my CF card. The QNX docs [1] states that only the OS image is bootable. I need the CF card to be bootable since there's no other drive to boot from. Thus, does that mean I can't benefit from the Flash file system image approach with my current setup?
I don't want to use the System Builder to customize my QNX OS or anything, since I still need the QNX SDP to run on the target.
It's been a while since I dealt with this, but the term "Flash filesystem image" is the bigger of the two. The filesystem image is the collection of bytes required to represent the filesystem on the flash device. It may hold such things as the OS image, your /tmp directory, your /home directory, and so on. The OS image, on the other hand, holds a second stage boot loader, the OS itself, and possibly some drivers.
I had an old DVR system which I was recording my CCTV cameras
with it. Product is:

Now I found my CCTV disk, it's normal 1TB HDD. I want to see RAW
videos recorded from CCTVs in this HDD. File system is not
detected by FindAndMount, Partition Magic, Recover My Files, etc.
Windows says it's RAW disk.
I can't access videos, but when I open disk image and read sector
by sector I see data there. How can I properly read and extract
data from this disk?
Thanks
These are stored in xfs or a linux file system on this unit,
go to pendrivelinux.com and get a windows installer to make a bootable pendrive.
I prefer ubuntu or debian, choose one of the two and make a thumb drive on a fresh thumb drive.
boot that up on a computer, plug in the dvr drive via USB-ide/SATA converter (About $14) most places.
you should see the disk mount and the files will be viewable.
you can then plugin a NTFS formatted hard disk and copy those off to the external drive and view them in VLC player for windows videolan.org
