Tool/software:
Hello IT,
I am working with the TI TDA4VM J721E architecture and would like to load R5F and C7x DSP binary firmware and tried to test the default example program for all available cores (R5F, and C7x DSP) through IPC mechanism.
We are referenced below link for symbolic link the binary firmware.
Please help the below queries:
- We tried to execute the default examples (rpmsg_char_simple &rpmsg_client_sample). we are not getting the excepted output as mentioned in the TI website.
- We are getting output for remote proc (rproc_id :R5F_MCU0_0) and for remaining cores, we are not getting the output.
- I have attached the screenshot and log.
