5.1. SDM RSU Support
In addition to implementing the actual RSU configuration flow, the SDM offers commands to interact with RSU:
- Get the flash address of the currently running image.
- Get details on the errors that occurred when trying to load an image which failed.
- Clear the sticky error information to be able to record new error information.
- Get the locations of SPTs.
- Load a specific image.
- Report the state of HPS software.
- Query the value of the current retry counter.
- Reset the value of the current retry counter.
The SDM commands must be called from EL3, the highest execution level on Cortex*-A55/Cortex*-A76.
The SDM commands are not publicly documented. Full support is offered for accessing the relevant services from both U-Boot and LIBRSU.
