12.1 Hardware Platform Not Recognized

GUID-FAED4302-873D-42A5-BDD8-EA9DDFE2734D-low.png Figure 12-1 Hardware Platform Error

The GUI will automatically connect to the AEVM (micro controller with the analog evm controller firmware) and then to the PMIC. Typically, if the GUI cannot find the hardware platform this is due to either a faulty USB connection or the GUI is attempting to connect to the wrong communication (COM) port. The hardware platform will enumerate as three devices; two CDC classes and one DFU class. From another program, like the device manager in windows, the user can verify which COM port is the ACCtrl and which is the ACCtrl Console. From the GUI option, the user should select the COM port number of the ACCtrl and not the ACCtrl Console. The AEVM supports a baud rate of 115200.

Other devices connected to the PC, may also enumerate at CDC class devices and the GUI may attempt to communicate with these devices. If no response is made from the device, then it is possible that the GUI will not attempt to connect to other devices until the current device responds.

Only one AEVM should be connected to a host (MAC of PC) at one time. The GUI does not support the ability to handle and respond to multiple AEVM devices connected to the host.
