Tool/software:
Hello TI Team,
I am working on the TDA4VM EVM with Processor SDK Linux/RTOS 11.0.
When I check the remoteproc cores from Linux, I see the following:
root@j721e-evm:~# head /sys/class/remoteproc/remoteproc*/name
41000000.r5f
41400000.r5f
4d80800000.dsp
4d81800000.dsp
64800000.dsp
5c00000.r5f
5d00000.r5f
...
root@j721e-evm:~# head /sys/class/remoteproc/remoteproc*/state
remoteproc0: attached
remoteproc1: offline
remoteproc2: offline
remoteproc3: offline
remoteproc4: attached
remoteproc5: attached
remoteproc6: attached
remoteproc7: attached
remoteproc8: attached
...
My requirement:
-
I want to run my own RTOS firmware on MAIN R5F cores and all 3 DSPs (C66x_0, C66x_1, C7x) build using the sdk.
-
Currently they appear in attached state, so I cannot stop/start them from Linux (
remoteproc
). - via echo "stop/start" > /sys/class/remoteproc/remoteproc*/state
Questions:
-
What is the correct way to make these cores available to Linux (offline state) instead of
attached
? - Also how to communicate with arm to remote processor(r5f,DSP)? via IPC means my understanding we need two firmware one is running in arm(send/receive) another one is remoteprocessor. But when i am building IPC examples its only building for remoteprocessor?
This will help me set up my environment to run custom firmware on these cores.
Thanks,
Regards
