• 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…
