TDA4VM: How to reset (enable or disable) MCU_CPSW(ethernet@46000000) using ti-sci api in mcu1 dynamically

Part Number: TDA4VM

Hi,

I want to use mcu1 to control the state of A72 core eth0, how can I dynamically reset (enable or disable) mcu_cpsw using TI-SCI API in mcu1 app? Or use other methods?

This SDK version is 08_02_00_04.(BOARD=j721e_evm)

Thanks.

Shuai,

The MCU_CPSW can be reset via WKUP_PSC registers controls. But I don't believe you can dynamically reset MCU_CPSW. You can bring it up once, and turn off once, But you can not turn it back on without resetting the SOC. Only a small set of subsystems (processor cores) support dynamic power management.

regards

Jian
