In this term, I have Microprocessors lectures and we're working on ARM Development with C/C++ and Assembly.
For a while I've been looking for an alternative for Keil uVision which is compatible with Linux Distributions (now using Arch) and able to assemble ARM and flash, but could not find anything. The most related platform was Eclipse but it does not look supports ARM Assembly and nothing that I read about flashing to STM32.
I don't want to work on Windows for ARM Development, is there any way to assemble ARM and flash it?
Very simple. Install STM32CubeIDE for linux and nucleotides board with your preferred STM32 uC. Follow the tutorials online
Be aware that Keil uses ARM's own compiler version 5 or 6 (current releases of Keil MDK support both v5 being ARM's legacy ARMCC, and 6 is based on clang/llvm). If you are following a course, and the course material is based on a different toolchain, you may encounter difficulties - or worse your tutor may not be able to mark your work. Just a consideration before you go off-piste.
Linux solutions are likely to be GNU toolchain based. An ARM GNU toolchain for Cortex-M can be found at: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm.
Flashing STM32 may either be done through a JTAG/SWD debugger usually using OpenOCD, or via the on-chip bootloader using a tool such as http://manpages.ubuntu.com/manpages/bionic/man1/stm32flash.1.html. Your hardware debugger vendor may have their own Linux driver, so worth checking. Mbed compatable boards present as a USB mass-storage device and can be flashed simply by copying the image file drive.
Building and flashing on Linux is only half the battle however; you will presumably want to debug your code too. GDB with OpenOCD or a proprietary driver will of course work, but raw GDB is not a pleasant experience, and you might want to have a more "visual" debug solution. IDEs such as STM32CubeIDE integrate the toolchain, flashing and debugging - but is specific to STM32.

I'm working on a BeagleBone Black (BBB from now on) with its stock Angstrom Linux.
I'm able to do GPIO/Analog programming using JavaScript, but I want to do it in C/C++.
I know the sysfs thing and /dev/mem, I want to know how to configure the GPIO and analog pins.
I can write C/C++ code for GPIO/analog reading writing, but have no clue what to do for initialization.
One way is the Device Tree Overlay, but I don't want to go for two different things for one purpose, since I can understand that it can be done in C/C++ but how??
It'll be helpful if I could alongside get some example related to both sysfs and /dev/mem for configuring+r/w of gpio &/or analog pins of the BBB (on Angstrom Linux, if this matters)
Derek Molloy has a great series of videos describing exactly how to do this, and more. His BeagleBone site has this address: http://derekmolloy.ie/beaglebone/
For C/C++ cross-development, the recommended path is to use Eclipse in Linux on your desktop computer. I personally run Ubuntu in VirtualBox under Windows. Derek Molloy describes this in full detail: http://derekmolloy.ie/beaglebone/setting-up-eclipse-on-the-beaglebone-for-c-development/
With the Beaglebone Black kernel (3.8), configuration can be done using Devicetree. It is shown in great detail in this video: http://derekmolloy.ie/beaglebone/beaglebone-gpio-programming-on-arm-embedded-linux/
OK, so Linux is the only way?
I've tried cross-compiling for other processors (bare-metal) using code::blocks, em::blocks & eclipse/ by using the respective cross-gcc toolchain for windows. Ex: arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) with Eclipse CDT was great and easy.
Isn't there any toolchain that would let me cross-compile for BBB/Angstrom-Linux on my windows laptop. I tried the linaro toolchain but even that didn't work
Thanks for those links, the Device tree seems good way, I want to try /dev/mem also, it looks more straightforward and is similar to bare-metal C/C++ programming once mmap is done.

I am relatively new to programming with embedded hardware although not new to programming. I purchased the STM32F407VGT6 Multimedia Board, TFT LCD, SD, Accelerometer, USB from http://microcontrollershop.com/product_info.php?products_id=5058&osCsid=9jkr9kor7d76qgvu76knsr0hp2. I thought I would be able to use the microC for ARM compiler but misread the demo version as 80 kb not actual amount of 8kb. To purchase this cost 300 and I really dont have the money for it. I have tried to find a different compiler that is compatible but so far have been unable to.
I did find people mentioning that Code Sourcery lite might work although no one mentioned this specific board but the free version does not come already integrated with eclipse and I was unable to successfully integrate it.
I am really at a loss of what to do since I would rather not have to buy a whole new controller, and screen just to continue my project and I don't want to pay to purchase this compiler
If anyone knows a free IDE (even if its free for students only) that is compatible with this board it would greatly be appreciated.
A compiler is required only to support the instruction set of the processor. Board specific support itself is not the responsibility of the compiler. Moreover in the case of ARM based devices, only the ARM core is the responsibility of the compiler; support for peripherals, and in particular the PLL clocking scheme for your part are also not the responsibility of the compiler. So the fact that your board is not mentioned in the documentation is largely irrelevant.
Some tool-chains and particularly IDE's from the likes of Keil (an ARM subsidiary) and IAR provide a huge amount of chip and board support. Both these companies provide demo versions, Keil's I believe is good for at least 32K, and the IDE also supports free GNU tools such as Code Sourcery, which has no restrictions on code size.
However in many cases and in particular the case of the STM32, a lot of the board support you need is available from the chip vendor. ST provide a standard peripheral library and ARM CMSIS (ARM's standardised Cortex-M support API), plus many other libraries besides. Keil actually ships ST's Standard Peripheral Library and CMSIS with its toolchain, but getting it form ST ensures the latest version. The libraries and manuals can be found ion the Design Support tab here. The board page linked in your question has a link to download example code to support the off-chip board peripherals.
So the upshot is that Code Sourcery or other ARM GCC distribution will work fine, but you may need to build your complete development environment from parts such as chip or board vendor supplied libraries plus an IDE/debugger environment such as Eclipse or uVision.
With respect to using Eclipse, there is an article here describing how to do it for the STM32 Discovery board; most of which is applicable to your board at least for building if not for debugging/flash programming - the Discovery board has a built-in STLink JTAG debugger.
Update June 2021
A lot of the above is out-of date ST have largely deprecated support for the SPL and do not even provide it for newer series such as STM32F7, replacing it with he STM32Cube framework.
Importantly however ST now provide a free IDE with a toolchain and CubeMX integrated: https://www.st.com/en/development-tools/stm32cubeide.html
Have you considered Yagarto?
http://www.yagarto.de/
It work on Windows and MacOS.
Or GNU ARM:
http://www.gnuarm.com/
Works primary on Linux and MacOS (also Windows through Cygwin).
Add code sourcery lite to your path, so you can use it from command line, then install Eclipse with CDT. When installed create new cross compile executable project. Enter arm-none-eabi (verify that this is prefix of your toolchain) and you should be able to compile and debug your project.
What is the command for selecting processor(MIPS R2000) in g++? Thanks
You'll probably need a cross-compilation environment for your target platform. You might find an existing one or you may need to build your own cross-compiler using the gcc toolchain. There's no single way to do this - it will depend on the specifics of the target architecture. Specifically, is there already an operating system (e.g. Linux, BSD, etc.) running on your target system? What kind of userland does it use - your build chain will need the relevant C and C++ library as well as any other libraries you need to build and run your software. Or are you coding straight against the metal? In this case, you'll want to find existing bootstrap code for getting the system into a sensible state for running your code - rolling your own will not be easy.
Generally, you're probably best off finding an existing developer community centred around the platform in question and asking for advice there. They may have step-by-step instructions for getting started.
Note that the CPU alone is only part of the picture - for example, the ARM architecture is very popular, but compiling code for Android devices (Linux kernel with Android userland), iOS devices (xnu kernel with BSD- and OSX-derived iOS userland), a Nintendo DS or a Playstation Vita (probably no multitasking OS at all) will be extremely different, even though they all use ARM chips, in many cases even the same instruction set generation.
I am pretty much new to embedded device programming world so pardon my ignorance if any.
I am cross compiling a C++ program on arm architecture with eclipse on ubuntu.
Then i have to burn the code and see the output with the device that has a linux kernel in it.
Then i came across a tutorial about cross compiling C++ program on arm architecture with eclipse on Windows. So my question is, Can i run this program (from windows) on my embedded device which has a linux kernel in it????
Thanks

If you are using a cross compiler, then the answer is yes. It should produce a linux libraries and executive file. You might need to adjust the files parameters (like set permissions and execute flag).
Yes.
eclipse is a great tool, especially when coupled with gcc. You can definitely use a ready-built compiler to extend eclipse as long as that compiler is available for Windows.
Here is a link to some documentation on how to change the toolchain in an eclipse project -
http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_prop_build_toolchain.htm
How can a cross compilation setup be achieved to allow compiling Cell Linux programs on a Windows PC using the cygwin toolchain? The cygwin tools provide a GNU compiler to use in building the cross compiler, and associated tools for the build process e.g. rpm, cpio, make, flex, bison and so on.
I am moderately confident this is possible, but unaware of anyone who has actually done this. It has already been done for x86 Linux, but I wish to use Windows, without requiring the use and overhead of a virtual machine running an entire 2nd operating system.
The Cell Linux toolchain is a patched GNU toolchain, with C and C++ compilers for the PPU and SPU processors, and associated binutils. The sources for the Cell Linux SDK for Cell Linux can be found here. The source RPMS here have build scripts for use with the rpmbuild tool on Linux.
The specific question is: how can a set of Cell Linux GNU compilers for the PPU and SPU processors be built, on Windows, using Cygwin.
I've never done it, so I can't give you step by step instructions, but I can give you a general idea.
The instructions you linked will serve as a pretty good outline, but there will be definite changes.
For the host PC, you can install gcc and other build tools from MinGW or cygwin. That will give you the windows native parts of your toolchain.
Then you'll need to download the sources for the cell portions of the toolchain and compile them (with the appropriate options, --target, etc.) using the build environment you just installed.
Then you download and compile the sources for libspe2, and you're done.
But I'll warn you - it sounds easier than it is. Be prepared to spend a lot of time on it.
Since you can already do this on Linux x86, why don't you just install Linux a virtual machine? Also, what might be even easier, is to install Portable Ubuntu for Windows. It runs Linux alongside Windows using coLinux. Although this may not be optimal, it is probably much easier than trying to compile everything on Windows.
the ps2dev toolchain can easily be set up under cygwin
http://ps2dev.org/ps3/Tools/Toolchain
You should be able to build a canadian cross compiler on Linux that runs on windows and creates code for PS3. Have a look at the excellent crosstools from Dan Kegel.
Did you check if the Cell/PS3 devtools for windows/cygwin work for you?
A set of tools compiled to run on Windows via Cygwin can now be found on Sourceforge.
Mike Acton has a long, detailed article on cross-compiling for PS3 Linux on his Cell Performance blog.
It may be a bit out of date, but the bits on setting up the toolchain and various SDKs might prove handy.
