Other Parts Discussed in Thread: SYSBIOS

Hi All,

We want to share resources like I2C between Cortex M4 core (IPU-1) and A15 during run time. A15 running QNX and M4 is running in sysbios ,is this possible ?

With regards,

Hi Jeyaseelan,

For I2C this setup is not recommended.

In the case of I2C, please consider if it would be possible to run the I2C instance for one of the A15 or M4, only during initialization, then let the other core take ownership of the I2C bus for runtime activities.

Regards,

Thanks for your answer Kb. As suggested will use dedicated core.
