I'm running Linux version 2.6.33.4 on an ARM9 and can successfully copy directly into the framebuffer using the command:
Code:
cat /usr/myfile.bin >/dev/fb0
I converted myfile.bin from a 640 x 480 x 24 bmp.
What I'd like to do is to have the ability to dump .bin image files directly into the framebuffer from a C program without shelling out to a cat command.

Is there any Linux utility to combine two or more binary files into a single binary file ?
View 7 Replies View RelatedIn a project I'm working on with a few other people, I got the task of writing an assembler. The last thing I do is convert the commands into a binary representation, and jam it into a file. Now one of my teammates said he'd like to be able to "reference" the code within another program. He said he'd be able to do this if the file I output is a Linux object file. I'm thinking it'd also work as an executable. Anyway, he said he'd like to be able to grab the file and reference the binary by address. I'm still fuzzy on this, and if you're confused with what I said here, please tell me so I can ask him for better details.Anyway, I'm aware that gcc can compile files to ".o", but that's only for C/C++, and my file is just binary. I'm also aware of "ld", but I haven't seen any use of it to help me. I'm happy to hear suggestions as to what I can do. If anything, I think I'll implement a few functions to grab the bits and hand them to him in an array or something.

i need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ "
new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.
I want to be able to disassemble a binary file, modify the assembly source, then assemble the modified assembly source back into a modified binary file. Purpose for this is pretty much just to play around with the Crackmes (www.crackmes.de) game.
Now, disassembly is easy, there are several tools that do it, including the standard objdump with the -d argument. However, how would you assemble an assembly source file created with objdump -d? GCC for sure doesn't want to assemble it in that format. What program, script, or arguments to GCC (none that I can think of) can be used to accomplish this? If someone also has some good tips for tools in general for Crackmes beyond what is standard in GNU/Linux I'd love to hear about it.
I have a binary file, which I need to process using my C++ application. Only thing I know is first chunk of the file is long, second chunk is int, third chunk is char etc... The binary file actually contains something like below. (which is represented in hex base).
D7 07 00 00 00 00 00 00 37 18 00 00 DE 07 ............ so on.....
I need to procees the file in the following way.
* I know the first data segment in my file is long. So it takes 4 bytes.
* so I need to read the first four bytes. That is D7 07 00 00.
* Then I need to reverse this as 00 00 07 D7.
* Finally I need to get the decimal value of above hexa decimal line. ( 00 00 07 D7)
* i.e. 00 00 07 D7 (in hex) = 7D7 (in hex- after removing leading 0 s) = 2007 (in decimal)
Like wise I need to process the whole file.

- traverse by level the binary tree
- posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file (i have to do this in 4 languages: c#,PHP from Xampp,java, python)

What is the Terminology called of a Binary using a file that is not part of it's self? An example would be when a browser uses a HTML file for it's interface. The binaries code has to know how to find it and so on. I imagine that the applications binary uses a system call and that another application takes over.

My question is whether the above code is portable. I presume it is, since the result is a binary PPM file which should be capable of being read across multiple computers with different architectures and different operating systems. But at the same time, all that the above code is doing is just saving the binary representation of unsigned chars on the harddrive, and there does not seem to be any reason why the binary representations of the unsigned chars will be identical across multiple computers.

View 5 Replies View RelatedI've had Ubuntu 11.04 installed on my desktop since it's release. Up until an hour ago, it was working fine. I clicked on an update from the update manager, now booting into a graphical mode is completely broken, (the start-up load hangs at 'Check Battery State ... [0k]'). I restarted my computer, and booted into safe mode, and launched the terminal. This all works fine. I then typed :
Code: sudo gdm start into the command prompt, hoping that I would be able to start things manually. Instead, it spat out this: Code:
gdm-binary[230]: WARNING: Unable to load file '/etc/gdm/custom.conf'. No such file or directory.
gdm-binary[230]: WARNING: Unable to find users : no seat-id found.
gdm-binary[230]: WARNING: Gdm Display: display lasted 0.070467 seconds
The last line was printed about 8 times, with slightly different times, before it gave up and failed. Some information which might help, I have Gnome 2, Unity and KDE (not sure which version), installed. My graphics card is the GTX 275, and I have driver the Nvidia driver 275.21. So yeah, I think the update has gone and moved custom.conf somewhere, but I have no idea on how to fix it. I have a graphics programming assignment due on Friday and I would be eternally grateful if I could get this fixed well before then.

View 5 Replies View RelatedI have a binary value which I receive from a controller. Say this binary value is 42. Just plain hex 42. If you would look at that byte in a debugger you would see 42.Now this value hold 8 bits each indicating a high or a low output. So 0x42 = 01000010b. Which means bits 1 and 6 are '1'.When I would want to find out which bits are set and which are not in a language like C, I simply do:
Code:
mask = 0x80;
if (binval & mask) {...}
etc..
However I am programming in TCL, and I try to do:
Code:
set mask 0x80
if { [expr ($binval & $mask) > 0] } {...}
etc...
this fails. At the moment the expr is executed, $binval is evaluated and substituted so the expression I am evaluating is
Code:
set mask 0x80
if { [expr ('B' & '0x80') > 0] } {...}
etc...
Eventually I got it working by converting the $binval into a '0x42' string value, like this:
Code:
binary scan $binval c byte
set byte [format "0x%0x" $byte]
set mask 0x80
if { [expr ($byte & $mask) > 0] } {...}
etc...[
Then the expression yields what I want. But this seems so stupid and clumsy. Isn't there a better way where I can compare two binary values without conversions?
