Interfaces Two main controllers on the Dev Kit, CPU and BMC. Interfaces such as USB, PCIe, SATA are offered by CPU, interfaces such as GPIO, I2C, UART are offered by BMC and/or CPU. Information below will indicates the main user interfaces come from BMC and CPU separately Interfaces - BMC Some of interfaces will be accessed either through IPMItool (command line) or WebUI, get detail from BMC Introduction & IPMI Software Support mgt.
