Hi,
I just recently downloaded the gnu toolchain
when i invoke the openmp flag, it fails
$ aarch64-none-elf-gfortran -c -o mod_constants.fppized.o -fopenmp -O3 -march=native mod_constants.fppized.f90 aarch64-none-elf-gfortran: error: unrecognized…
Dear all,
Most mobile phones contain an ARM-like application processor AP for general user applications and a base band processor for the radio software stack, could you please elaborate on the following:
1. Do the AP and the baseband processor communicate…
How does a developer prevent an attacker from taking control of a program when the developer is providing the tools to the attacker? What are code reuse attacks and how can the Arm Architecture remove the vulnerabilities? How can someone use these architectural…
Does anyone know if there will be a release of the GNU-A tools for MacOS anytime soon?
Dear all,
I am on the process of switching to GNU GCC for compiling an already working project. Most of the functionality has been tested. There is a failing test though: The USB VCP drivers do not seem to perform good.
The client side (PC-Windows) is…
hi everyone,
i'm new with ARMprocessor and dont know too much about DS-5. just alittle bit from my Softwares >>> SoC EDS 17.1 (from Altera) - DS-5 5.28 and my OS is Windows 10. I am using DS-5 for my SoC FPGA (DE0_Nano_SoC) Altera, which…
I've read everything I could put my hands on to figure this out but have had no luck. I installed the win32 exe gcc-arm-none-eabi-6-2017-q2-update-win32-sha2.exe but it is not found by Eclipse. I know it says to leave the environment variable blank…
Presently, I use ARM cc compiler with GNU Linker, And I've been trying to move completely to the ARM toolchain. But I am not sure how to add symbols in ARM linker while using scatter file..
In ARM GNU linker, while using the .ld file, I could add my…
Hi,
I'm in the process of porting my Flash memory check for STM32F0 from gcc to mdk. The gcc check follows a method similar to:

This is a great solution since beside the CRC…
Hello,
I've a project which are started with arm-none-eabi-gcc and added in the last time the ARMCC. The linker configuration can't easy converted.
At the moment I search for a solution to define in the scatter file like the gcc linker file. This…
Hello, some time ago I started to play with CortexM4,
I bought a Discovery Board with a STM32F407VG in order to be programmed with uVision from Keil.
I am developing a project where the money is very restricted, that's why I was using a free licence from…
A lot has happened since the last GNU Tool chain performance update. The GCC and glibc communities have been hard at work since, improving the compiler and the library with new usability, language, debugging, security and a myriad of other features…
We are pleased to announce the first Arm's release of pre-built GNU cross-toolchain for the A-profile cores: GCC 8.2-2018.08. The GNU Toolchain for the Cortex-A family is a ready-to-use, open source suite of tools for C, C++ and Assembly programming…
One of the major attractions of adopting the Arm Cortex-M architecture is the healthy ecosystem of hardware and software development tools that support all Arm-based products.
Most engineers prefer to have a choice of different options that appeal to…
In this blog we will focus on two components of the GNU toolchain, the GNU Compiler Collection (GCC) and the GNU C library (glibc). A full toolchain contains several vital components like assemblers, linkers and debuggers, but in…
In a previous article I wrote about migration from armasm (the legacy Arm assembler) to Arm Compiler 6 (AC6). This was useful for users who were already using the Arm toolchains for their builds. But what of gcc users?
Previously there was a reasonably…
Hi Experts,
For Cortex R and M processors Linaro has recommended the GCC arm-none-eabi 4.9 whereas for A series processors it is recommending normal GCC eabi.
what is the key difference between the same ?

I'm reading OReilly embedded programming book. After reaching 2.7. Initialize the Hardware i have problem understanding things. i didn't understand some part about 2.7. and locating and linking. i was thinking maybe if i do it myself on my lpc1768…
Hi,
is there a GNU #pragma message equivalent in armcc/Keil? I would like to output message on compilation to stdout regarding current program configuration or unimplemented features...

Please provide routes to any other document/tutorial that would add value…
How to use GNU ARM binutils for cortex-M4? When I try to compile with -mcpu=cortex-M4 -march=armV7e-m I get 'bad value in switches'.
While I using Eclipse, rarely I needed to use the MAKE or when I needed the knowledge he had was enough.
Now I need to do some actions, such as copying files from one directory to another whenever the presence of one or another variable and when the directory…
Dear all,
I am trying to build the example startup_cortexA15MPcore (provided with DS-5) using GNU toolchain. The example is originally designed for build using ARM standard tools, and the following variables are hence defined :
