    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?

    Hi All,

    I am using UART to receive values and then write those values to SRAM. I am using the Texas Instruments Stellaris LM4F120 board.

    For this purpose, I am using the memcpy() function to write the received values over UART to my SRAM base address defined…

    For the SRAM with Cortex M0, does it need to support byte write?

    What restrictions do I have with Cortex M0 if the SRAM only support 32-bit write?

    Hello, when I use stm32f103xx, I am confused of  one of the boot modes it supported. One of  the boot modes is booting from embedded SRAM while the I-BUS of Cortex-M3 is connected to FLASH only . When boots from SRAM,  how Cortex-M3 fetches instructions…

    Hello:

    I need more  RAM size on MSP2 board.

    in Keil  uVison 5, I add a simple code to write then read testing.

    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 …

    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…
