  • Program MPS2 with .axf file

    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…

  • Cortex-M0 example system

    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…

  • How to Debug CM3 DesignStart in the FPGA

    I use the ARM Cortex-M3 DesignStart Eval on the FPGA platform, I use J-link to download the program to the system but the system is not properly implemented. I downloaded the generated Hex file via J-link to the FPGA development board via Keil. Is the…

  • SWD issue in Cortex-m0

    We are using Cortex-M0 DesignStart Pro to design MCU. When we use SWD to download grogram to flash in FPGA(Cortex_m0 mcu inside),  we cannot to connect keil with FPGA, and Keil shows:" Could not stop Cortex-M device!Please check the JTAG cable. "…

  • Different Address of Reset Handler!

    Hi there,

    Why the address of reset handler is different from waveform and assembly code for hello testcase?

    This is obtained after compiling hello.c using Keil uVision 5.

    Reset_Handler
    0x000001c0: 4809 .H LDR r0,[pc,#36] ; [0x1e8] = 0x2a1

  • CoreMark 和编译器性能

    原作者: danowens

    原帖地址:CoreMark and Compiler Performance

    CoreMark正在迅速引起人们关注,成为事实上的 CPU 性能基准测试标准。这是一款易于编译和运行的免费工具,能返回一个有价值结果,简化了性能分析。与上世纪 90 年代的
    Dhrystone
    一样,我们发现开发人员正在试图根据 CPU 性能判断编译器效率。这种判断往往会令人误解,因为CoreMark 与之前的Dhrystone 一样,属于特殊用途的基准测试小工具,它以 CPU 性能而非广泛的嵌入式软件工作负载为目标…
