  • Page 90: Bmc Api (Application Programming Interface)

    Hardware/Software Interface BMC API (Application Programming Interface) The BL51E uses a generic command interface for communication between the host (CPU) and the controller (BMC). Application software uses command packets to communicate with the BMC. The application software controls the BMC via I2C/SMBus. The device address is 0x4D (in 7-bit, non-shifted notation) or 0x9A/0x9B (in 8-bit, shifted notation, write/read).

  • Page 95 5.3.1.4 Reset Signal Blocking These commands allow blocking of BL51E reset inputs. The setting is persistent, i.e. it is stored in non-volatile memory. In a system with master and slave CPU boards, normally the slave boards will get a reset whenever the master board resets.
  • Page 96 Hardware/Software Interface 5.3.1.5 Software Reset These commands allow performing CPU resets under application software control. Different types of resets are available: SW_RESET issues a “warm reset”.  SW_COLD_RESET issues a “cold reset”.  SW_RTC_RESET issues a “cold reset”, together with an RTC reset. ...

  • Page 100 Hardware/Software Interface 5.3.1.8 Error Counters The error counter commands allow querying and clearing error counters. The BMC provides error counters for each type of error that can occur. Using this information, the application software can determine how often certain errors have occurred, but it is not possible to determine the chronological order of the errors.
