Iuse the ccplex of the nx board to run the bare metal program written by myself. The program wants to implement ivc communication with freertos in the r core. But But R-core freertos aborts unexpectedly when I run the program. For freertos to run, does the A core need to send some characteriastic information to the R-cortex, such as heartbeat?

Hello,

It may be a little complicated.

You can take a look at Kernel communication with spe - Jetson & Embedded Systems / Jetson TX2 - NVIDIA Developer Forums

Though it may be a little outdated, the basic framework should be same.

Thanks for your reply!

Do you mean I need to follow the code of kernel/nvidia/drivers/platform/tegra/tegra-aon.c and kernel/nvidia/drivers/platform/tegra/tegra-aon-ivc-echo.c to implement a program that can communicate with rt-aux-cpu-demo-fsp/drivers/ivc-channels.c? In fact, I did this before, but the running of freertos always stops unexpectedly. Do I need to implement some additional modules to keep freertos running properly?
