AST2050 Firmware UpdateThe BMC will allow users to upgrade firmware image on following entities: BMC All other upgradable entitiesThe update capability shall be provided on local and remote interface.DOS Recovery Utility SOCFLASH UtilityWebUI Update Remote update can be achieved through remote Web console.Temperature MonitoringAST2050 supports temperature sensors through external sensors such as W83627EHG or TPM75. Temperatures arethreshold bases, which supports UCT (Upper Critical Threshold), UNRT (Upper Non-Recoverable Threshold). Thesevalues are decided by thermal engineers to meet safety standards. The other sensors are discrete base temperature sensors.Below is an example of temperature thresholds. Prefix “Mainboard” only appears in Web UI.Temperature Sensor Number LCT LNCT UCT UNCTCPU0 Temp 44h N/A N/A 102 98CPU1 Temp 45h N/A N/A 102 98MB Temp 40h N/A N/A 75 70FP Temp 41h N/A N/A 50 45BP Temp 43h N/A N/A 55 52DIMM Temp[1] 42h N/A N/A 100 95PROC_HOT0 [2] 21h N/A N/A N/A N/APROC_HOT1 [2] 22h N/A N/A N/A N/AIOH_THERMALTRIP[2] 25h N/A N/A N/A N/AIOH Temp 46h N/A N/A 105 95[1] DIMM Temp can’t be read when host in BIOS POST.[2] These sensors belong to discrete temperature sensor.Voltage MonitoringAST2050 supports voltage sensors through external sensor W83627EHG. All the threshold voltage will support UCT, UNCT,LCT and LNCT assertion and de-assertion. These thresholds are decided and fixed by EE engineer and not allowed for userto change it. Due to the calculation deviation, +-0.063 of reading value is acceptable.Chapter 4 — BMC74
