Tool/software: TI-RTOS
HI：
Software version: TI_RTOS 4.3, hardware version: AM5728-ES2.0, custom board
Apply a 640-byte memory on the linux side via the CMEM_alloc2 function and use CMEM_getPhys to return the physical address. Then use MessageQ to send the virtual address and physical address to the DSP. What should I do to operate the CMEM memory on the DSP side?

Hello,
Please take a look at our Big Data IPC example for an example CMEM application.
The source code can be viewed at
C:\ti\processor_sdk_rtos_am57xx_5_00_00_14\demos\bigdataipc\host_linux\simple_buffer_example

Hello:
Thank you for your reply. I am prompted with the following error when running app_host on the board. What should I do?
ln -sf /usr/bin/simple_buffer_example/release/server_dsp.xe66 /lib/firmware/dra7-dsp1-fw.xe66
echo 40800000.dsp > /sys/bus/platform/drivers/omap-rproc/unbind
echo 40800000.dsp > /sys/bus/platform/drivers/omap-rproc/bind
/usr/bin/simple_buffer_example/release/app_host DSP1
Thanks
Hello,
Make sure to disable the OpenCL application that is running by default as it uses the same resources as the big data example.
> systemctl stop ti-mct-daemon.service
See step 1 of the "How to Run the Example" section:
If you have any questions please let me know.
