Hello !
It seems like the binaries for the windows version of arm-linux-gnueabi and arm-linux-gnueabihf has been removed in gcc8. Have the support for windows been removed or will it appear ?

Hi,
I have downloaded the new AArch64 GNU/Linux target (aarch64-linux-gnu) binaries and they are working fine.
Can someone please let me know the the configurations flags used to build these toolchains.
Earlier I have used ABE tool (from Linaro) to build…
Hello,
I 've a module with a Cortex-M4 Vybrid VF61 processor and an installed linux.
The installed linux does not provide gcc and gdb for native compiling and debugging.
Please, can anybody tell me, where I can download a prebuilt gcc and a prebuilt…
Recently we have updated the armgcc toolchain version to 8-2018-q4-major, and we found that our previous memory definition way in linker file is invalid.
Previously, we are using below LENGTH() way to calculate the origin for a defined memory:

I am trying to get a cross-compiler built to run on my Windows box. One route I'm trying is to use Cygwin to build the compiler.
I've tried several attempts with the latest sources but hit upon some compile snags. Has this been done before? Google…
Hello.
I'm fairly new to embedded software development, and could use some clarification on how to generate .elf files from .c files.
I've recently downloaded the following toolchain installation:
Hello,
I am trying to compile some asm code with operand unable to be used as immediate, but compiler does not generate error but produce strange binary code, hard to detect erroneous code.
The source code

I've noticed that arm gcc, when compiling code for Cortex-M0 (at least) seems to generate instructions:
adds r0, r2, #0
Where I'm pretty sure that it the same as:
movs r0, r2
In fact, I can disassemble a relatively substantial program and not…
hi,
I'm using arm-none-eabi-gcc 5.4, I'm not sure if there's problem as followed:
if ( ptr && ptr->member ) {

The question is that, when compiled with -O1 or -O2, CPU will execute the condition (ptr->member…
Dear All,
To use 'arm-none-eabi-gcc' I've got a gcc-arm-none-eabi-6-2017-q2-update.ar.bz2 from ARM Toolchain.
But I came across the following issue GLIBC_2.14 and GLIBC_2.11 need to use.

Hi, I am trying to find out where exactly the soft floating point code used in eabi for a M0+ comes from. When i compile a program using floating point using gcc_eabi, it generates code to carry out this operation. ( code included).
I downloaded the…
Dear Sir,
How to disable floating-point instruction generation with aarch64 GCC compiler ?
We want to use software to do floating-point calculation.
But always has error messages as below:

I have a confusion regarding GNU compiler licesnce. I gone through GNU ARM Embedded Toolchain license and noticed it has built with "newlib" C standard library instead of glibc to avoid licensing issue.
But still i want to clarify my confusion…
Hello,
I'm developing a commercial software for MCU which is built by GNU ARM Embedded Toolchain. I want to sell the programmed device (product) and I don't want the source code to be released.
When I compile my code using a -Wl,--verbose I see…
Is there a possibility to reinterpret cast an uint32x4_t into a uint8x8x2_t using intrinsics?
Sincerely
Hi @ all,
I have an uint32x4_t on which I want to perform a count of leading zeros and a table lookup with intrinsics. The table lookup should be performed like this:
0 1 2 3 4 5 6 7 8 9 A B C D E F Data…

…Hello all,
I recently installed GNU ARM Embedded Toolchain on windows plataform to use it with Eclispe Neon.3.
I had to install 32 bit version because I did not find 64 bit one unless I start compiling the source code.
When will it be planned to release…
Is it just me or are the install instructions for gcc-arm missing some information? I've downloaded gcc-arm-none-eabi-6-2017-q1-update-linux.tar.bz2 and uncompressed it. The readme file in there states that all you have to do is add the bin directory…
Over on http://gnuarmeclipse.github.io/toolchain/install/, I see this:
starting with version 6.x, GNU/Linux toolchains are 64-bits applications, and should work directly on most modern distributions;
Is this a project choice for the GNU ARM Embedded project…
While building the GNU ARM Embedded toolchain from the source invariant download, I noticed that pretty much the first thing to happen is downloading and unpacking of a bunch of additional source packages: gmp, mpfr, mpc, ISL, expat, etc.

Hi Experts,
I previously used arm-none-eabi 4.9 from Linaro for the bare metal arm compilation.
I wonder whether the recent release from Linaro site on bare metal compiler is as in the following link,
I've only used AVR and Arduino before which really don't count as embed! so I have a little trouble compiling my blinky.
I'm mainly a PC programmer. I have an LPC1768 dev board!
Here's what I did:
I first installed arm-none-eabi-gcc on…
I have searched information on Bit-Banding in Cortex-M3 and M4 with the GNU GCC ARM EABI NONE, I have seen basic examples on the internet but none works with GNU GCC also seems that no intention to have such feature implemented.
Can someone tell me if…
