1 Overview 2 -------- 3 P1022ds is a Low End Dual core platform supporting the P1022 processor 4 of QorIQ series. P1022 is an e500 based dual core SOC. 5 6 7 Pin Multiplex(hwconfig setting) 8 ------------------------------- 9 Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex 10 via hwconfig, i.e: 11 'setenv hwconfig usb2' to enable USB2 and disable eTsec2 12 'setenv hwconfig tdm' to enable TDM and disable Audio 13 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz) 14 and disable TDM 15 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio 16 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources 17 is 11MHz), disable eTsec2 and TDM 18 19 Warning: TDM and AUDIO can not enable simultaneous ! 20 and AUDIO codec clock sources only setting as 11MHz or 12MHz ! 21 'setenv hwconfig 'audclk:12;tdm' --- error ! 22 'setenv hwconfig 'audclk:11;tdm' --- error ! 23 'setenv hwconfig 'audclk:10' --- error ! 24
