hello,

use API(sc_pm_reset) to SCFW in kernel, but fair.

use API(sc_pm_set_resource_power_mode) to SCFW in kernel, its successful.

sc_fw_api_qx_b0.PDF:

Only the owner of the SC_R_SYSTEM resource or a partition with access permissions to SC_R_SYSTEM can do this1.png

How to get permission?

BRS 

Thanks

Hi Grayli

one can look at below link describing resource management

System Controller Firmware 101 - Resource management service 

Also please look at sect.4.6 Hardware Resource/Memory Isolation sc_fw_api_qx_b0.pdf

SC_ERR_NOACCESS error comes from check if the partition from which one is
trying to access the resource is non-isolated (use XRDC2 to isolate).

Best regards
igor

hello,igor

IMX8 does not have a hardware watchdog, Can the imx8 use SCFW's watchdogs?
