I think I found the answer to my question. There is an \"fmacs\" instruction for VFP which may do the trick which does scalar computation on NEON/VFP registers.
I am trying to cross compile Qt with WebKit for an embedded arm device (freescale processor). I have a arm-none-linux-gnueabi toolchain.
My ultimate goal is to do some programming for the Ang开发者_如何学JAVAstrom Linux (or Debian or other Linux distros), on QEMU emulating ARM processor board s.a. Versatile board. I am happy to experie
I have a problem is connected with BKPT instruction on ARM v7 on Linux 2.6.35. The main reason is that the address of fault instruction (bkpt) is not correct and does not correspond to ARM v7 manual.
When compiling this program with arm-elf-gcc-4.5 -O3 -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=softfp:
When you build a gcc toolchain there is the possibility to build it asarm-elf or as arm-none-eabi, but what is the difference?
I\'m trying to figure out how to communicate with a bricked phone. Sometimes when custom firmware is flashed, it destroys the boot process.This leaves the device without the ability to naturally load
I\'ve been looking for some C# compilers for Linux and after a long search I\'开发者_运维百科ve encountered some projects that are very interesting:
I have a C project which was previously being built with Codesourcery\'s gnu tool chain. Recently it was converted to use Realview\'s armcc compiler but the performance that we are getting with Realvi
In the Cortex-M3 instruction set, there exist a family of LDREX/STREX instructions such that if a location is read with an LDREX instruction, a following STREX instruction can write开发者_运维技巧 to
