Tool/software:TI-RTOS Hello. I'd like to have any advice about mmu setting for pcie shared memory. I'm using AM5728 and TI-RTOS. My custom board is pcie EP device.(The windows host can read/write board memory by
I have also looked at the memory domain API as a possible way to create shared memory, it seems plausible. Looking at some comments made by @andrewboie regarding memory domains the limited number of them currently available might not allow using it for this purpose, if there were an unlimite...

I'm trying to test IPC using shared memory transport to exchange messages between A15 and DSP. I want to allocate message once on each core and then reuse it indefinitely. Platform: AM5729 on BeagleBorad-X15 pdk_am57xx_1_0_15 processor_sdk_rtos_am57xx_6_00_00_07 bios_6_75_02_00 C...
As you said, we can see there are 2GB(0x40000000 - 0xBFFFFFFF) ddr memory in imx8mq Cortex-M4 region. It means there are 2GB memory can be shared between the IMX8M M4 and A53 cores? If so, I encounted problem when run rpmsg_lite_str_echo_rtos as below: when imx8mq rpmsg share...
The Linux IPCF Shared Memory Driver enables communication over shared memory with an RTOS application running on a different core of the same processor. The driver is accompanied by a sample application which demonstrates a ping-pong message communication with a RTOS application (for more details se...
ory or virtual memory. It may be owned entirely by the CPU that is running the software, or it may be shared by several CPUs. Memory can belong to another CPU on the same SBC, to another SBC in the same chassis, to a chassis across ...
shared memory objects. Fix would be to use prefix "\Global" for event and shared memory names, when server creates the objects. Note that in this case, mysqld.exe that started in user session would needs CreateGlobalObjects privilege. On Vista with UAC, this can be accomplished e.g by ...

That causes trouble in a multicore environment, because each CPU is referring to its own copy. By default, the Memory Protection Unit allows access to all memories from all CPUs. I don't know much about safeRTOS, but you probably need to change the MPU configuration to allow access to ...
