Unlike the Design kit makefiles, in which tool-chain (Keil, DS5 or GCC) can be chosen, the Prototyping kit makefiles uses only DS5.
Is it possible to receive Prototyping kit makefiles that support tool-chain selection and in particular GCC?
Hi,
I am just performing the first steps with the DesignStart Eval Edition (Cortex-M0), trying to compile the verilog sources to get a simulation running.
So I changed /systems/fpga_testbench/trl_sim/makefile to use gcc and modelsim and now I want to …
Hi,
I am using the MPS2+ board to debug my DesignStart Cortex-M0. The core is up and running and now I want to program the onboard SRAM. On the SDCard I can see that \MB\HBIO263C\AN387\images.txt expects an axf file.
Is it possible to generate an .axf…
Hi,
I am working on a GPIO IP for Designstart Pro Cortex-M0. Now in my Simulation there are some Read-Modify-Write cycles in order to set only single bits in a 32 bit register.
If the GPIO register is 0x0000000X and I just want to set bit 16, GCC produces…
Hi,
I'd like to try and use external BRAM as the I/D memory for the Cortex-M1 DesignStart package for Xilinx FPGAs. The reference examples for Arty boards use the internal TCMs.
I've built a design in Vivado with a BRAM connected to the AXI3 port mapped…
In my previous blog on, Running HPC Applications on Arm, I talked about lots of the work that has been going on about getting a wide range of HPC applications running on today’s Arm systems. Today, I want to focus more on some of the key optimizations…
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…
Overview of stack size requirement estimations in Cortex-M based applications
“How much stack memory do I need for this application?” - This is a common question for many software developers working on applications that run on microcontroller…
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…
I've the following implementation for a svc exception handler on a cortex-m0:

Chinese Version: Arm Cortex-A 处理器和 GCC 命令行
The GNU Compiler Collection’s (GCC) command line options for Arm processors were originally designed many years ago when the list of available processors and variants was much shorter than it is today.…
EDIT: Stable GCC 7.1.0 is already released - see first reply below for details!
If you're very impatient waiting for the full GCC 7.1.0 release (expected this month), you can try experimental GCC 7 version with your ARM microcontroller right now (…
Hello,
I would be interested to try the new features of the ARMv8-M architecture, in particular v8-M TrustZone, but I can't find necessary tools in order to do so.
1. I need a toolchain that supports the new instructions introduced with v8-M (SG, BXNS…

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 evaluating the ARM DS-5 and Linaro toolchains and the FVP model simulators. I'm starting with the DS-5 Community Edition and the Foundation Profile simulator before advancing to the commercial tools. So I have a few questions:
Hi,
I am using "gcc-arm-none-eabi-4_9-2015q1" to compile ARMv8 - A53/A57 code and getting following errors while compiling assembly files -
I am giving -march='armv8-a' option. I am not sure how to resolve this ?

Hi all,
I'm new to DS-5 and ARM development. I am trying to develop a Linux application to run on a Ka-Ro TX25 module. This module consists of a Freescale i.MX257 processor. This module comes with RedBoot and Linux 2.6.31 preinstalled. I would like to…
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'.
Hi,
Can anyone help me in porting ARM code which is compatible in Development Studio 5 to GCC platform?
Please help me in identifying how Macro and global directives are defined in GCC platform?
Thanks
