  • PROCESSOR-SDK-J784S4: 使用sdk-linux-j784s4-evm-10_01_00_05，使用设备树k3-j784s4-evm-csi2-ov5640.dtbo启动linux后，使用devmem2读取dphy寄存器出现内核panic，请问是什么原因？该如何解决？

    TI 认为已经解决
    Part Number: PROCESSOR-SDK-J784S4 我使用了k3-j784s4-evm-csi2-ov5640.dtbo，启动后，使用lsmod查看，ov5640已正常加载上了， 但是使用devmem2读取dphy寄存器地址0x4504048出现内核panic。 除了 0x04504048地址，我还尝试访问了0x4590B00, 0x04504040, 0x04504060, 0x04504100 等寄存器，均出现相同的panic。

  • PROCESSOR-SDK-AM64X: AM64X如何解决R5和A53共享内存数据一致性

    已解决
    Part Number: PROCESSOR-SDK-AM64X 我要在R5和A53做共享内存，比如我在0xb000 0000来做，A53通过MMAP将 0xb000 0000映射出虚拟地址，A53(运行linux)对改虚拟地址写数据，然后R5到0xb000 0000读取数据，如何解决一致性的问题？现在测试发现A53的数据会进入cache，导致R5读不到
