Does anyone know how to solve this problem?

I want to try SUSPEND/ DEEPSLEEP function in AM3352 based on PM user guide: processors.wiki.ti.com/.../Linux_Core_Power_Management_User's_Guide_(v4.1), and I cannot recover the system from both SUSPEND/ DEEPSLEEP status. "wkup_m3_ipc 44e11324.wkup_m3_ipc: could not get rproc handle" is the only error in dmesg; therefore, I want to ask about this issue.

Is this a custom board?

Yes.

Do I need to enable any configuration or something ? I have already followed the steps in Linux_Core_Power_Management_User's_Guide_(v4.1).

I have asked the PM experts to comment. They will respond here.

Hi Sophia,

Do you use AM335x TI board (EVM, SK, BBB) or this is custom board?

The latest power management wiki is:
