My board hardware is connected to CPLD through I2C of AST2500, BMC reads and writes CPLD register through I2C, and then CPLD controls power on and off.<br>

<div> So, I think <span style="caret-color: rgb(50, 49, 48); font-family: "Microsoft Yahei UI", Verdana, Simsun, "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size: 14.666666984558105px; background-color: rgb(255, 255, 255); display: inline !important">The

Please help me to suggest what to do next, which can solve this problem and adapt well to the code of openbmc community.</div>

> Regarding power control, I read the codes in the following two directories(github.com/openbmc/x86-power-control.git & github.com/openbmc/skeleton/tree/master/op-pwrctl). The power control is controlled by GPIO, but the power of my board is controlled by CPLD.
<br>
<br>
The x86-power-control implementation uses GPIOs from the BMC, but those<br>
GPIOs are wired to a CPLD for the signalling. The CPLD monitors the<br>
GPIOs to know when to begin the power sequence. This is what we use on<br>
Tiogapass.<br>
