  • ARM Cortex ICode, DCode, System buses

    Note: This was originally posted on 26th February 2009 at http://forums.arm.com

    I'm a bit confused about the bus structure and memory model of ARM Cortex M3. First of all, does Cortex M3 actually have 3 physically separate buses coming out of it?
  • LPC2368 Watchdog Timer

    Hi,

    I am using LPC2368. It has pretty complex code running with 1 Timer interrupt (100uS continuous) , 2 UART interrupts, 1 SPI Interrupt, 1 USB interrupt and main loop.

    Watchdog timer is of 5 sec and is feed in main loop and in different places.

    System…

  • CMSDK - design multi-master bus

     asked: "with the M3 designstart CMSDK, is it possible to design multi-master bus? In the IoT Cortex-M TRM, only an ahb-lite structure is illustrated. That document does mention AHB and APB expansion through INTEXP[1:0] but what if there are more…

  • DesignStart Pro: APB on FPGA via Quartus Prime

    Hello,

    I try to implement the Cortex-M3 processor on an FPGA via Quartus Prime. I set up the SSE050 Subsystem and tried to connect several peripherals to the board. I want to test the functionality with a uVision project lighting some LEDs. To have access…

  • First compile, verilog files missing

    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 …
