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 !
