• AXI narrow burst support

    I have an AXI4 initiator that issues a 32-bit read request to an AXI target (memory) via a 64-bit wide data bus.

    I set the ARSIZE parameter to 2.

    The data in the target memory are the following:

    addr   : data
    0x000: 64'h 77_66_55_44_33_22_11_00

  • SMMU in Mali GPUs

    Hello everyone!

    I'm wondering if any Arm Mali GPUs, except for Mali-G78AE, are connected to a SMMU.
    I have checked that Mali-G610 isn't connected to SMMU (at least in sysfs & device tree).

    It's common to have peripherals isolated via SMMU or…

  • RE: What should be LR(link register) value for Cortex-M7 core?

    The least significant bit in the LR register specifies that the code at this address is a Thumb instruction and all Cortex-M instructions have Thumb encoding. So this behavior is expected. All instructions of Cortex-M cores must be located on even addresses…

  • RE: printf output via DAP

    Hello,

    As you have found, Event recorder printf is not supported in Arm Development Studio. If you switch to semihosted ("Breakpoint") output, you will see the output in the Arm Development Studio Target Console.
