Hi,

I'm new into  mixing C and ASM on Cortex M3 using keil, here is the question,

Suppose that a function tries to access some memory that is not in the system, something like this, the system crashes with the hardfualt exception, so my question is…

I am using the KEIL MDK-5, assembly. The project compiles without some problems, but when i see the disassembly the assembler change the inmediate value

Assembler substitute one instruction for another

My code:

The instruction: SUBS    R2,#0xC7

the assembler…

I am trying to use arm softcore along with my RTL in Kintex 7 board. What tool set is suggested? for both hardware and embedded development?

Hi,

I am trying to build software(esp device driver support) for a particular Cortex-M33 microcontroller offering from my company. I have a few questions about software IDE and tools supported by ARM:

• Does Keil MDK (uVision) version 5.26.2 support building…

Hello,

I'm a fresh guy on the KEIL, and here are 3 general questions, thanks any masters helping on it.

1. Is it possible to build a library by keil which could be linked in another project, while in this project, the device CPU is different w/ the…

Hello, I am looking for information about programming an ARM M4 firmware to basically broadcast serial information to a bluegiga WF121-A wifi module. My device will receive 2 serial inputs and I want the serial input packets to be sniffed and broadcasted…

I have to port a solution i am working on for Cortex-M4. I need to build,profile and later optimize.
Can somebody please suggest which all tool will be helpful. 

Hello, 

so I was working on Tiva C launch pad and coding using this environment, I noticed that this compiler has major difference from others so I will list some of the problems I faced as questions hoping someone would answer : 

1- In case I need to use…

I would like to know if any of the compilers/libraries for Cortex-M support the std::thread type (from the <thread> header) or if there is any plan to support that in the near future. I am interested in both Keil MDK / DS-5 or GCC for ARM. Thank you!…

Hi,

I'm starting to explore this technology by running the TrustZone example application in Linux using GNU ARM Toolchain. This example is provided by a CMSIS software pack containing this example called "TrustZone for ARMv8-M No RTOS" which I was…

Why should we call secure function in handler mode? What is the design purpose for this?  As we know, none-secure side can also call secure function in thread mode.

Hi,

II refer to the example MCU system level in the document "arm_cortex_m0_designstart_eval_user_guide", put it into MPS2+ after synthesis, the software uses the following example in this directory.

D:\CMPS3\AT510-MN-80001-r2p0-00rel0\systems…

I want to run Cortex M-3 soft processor core on ZedBooard. I have downloaded the cortex M-3 IP core, created a deisgn by integrating Zynq Processor with Cortex M-3 processor and generated bitstreams.

I have also included the provided SW repository from…

Hi,

I am trying to get familiarize with the SoC design provided with Desgin Start Cortex-M0 Eval version.

Here is my setup:

1. ARM Cortex-M0 core
2. Design Start Eval  with CMSDK used for SOC design.
3. Keil MDK – mdk_pro uvision V5.25.2.0
4. Vivado Tool used…

Did you know that there are 23 billion IoT embedded devices currently deployed around the world? This figure is expected to grow to a whopping 1 trillion devices by 2050!

Less known, is that 80% of IoT devices are based around Arm’s Cortex-M microcontroller…
