|  | Pin Multiplex(hwconfig setting) | 
|  | ------------------------------- | 
|  | Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex | 
|  | via hwconfig, i.e: | 
|  | 'setenv hwconfig usb2' to enable USB2 and disable eTsec2 | 
|  | 'setenv hwconfig tdm' to enable TDM and disable Audio | 
|  | 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz) | 
|  | and disable TDM | 
|  | 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio | 
|  | 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources | 
|  | is 11MHz), disable eTsec2 and TDM | 
|  |  | 
|  | Warning: TDM and AUDIO can not enable simultaneous ! | 
|  | and AUDIO codec clock sources only setting as 11MHz or 12MHz ! | 
|  | 'setenv hwconfig 'audclk:12;tdm'	--- error ! | 
|  | 'setenv hwconfig 'audclk:11;tdm'	--- error ! | 
|  | 'setenv hwconfig 'audclk:10'		--- error ! |
