  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. Pin Multiplex(hwconfig setting)
  6. -------------------------------
  7. Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex
  8. via hwconfig, i.e:
  9. 'setenv hwconfig usb2' to enable USB2 and disable eTsec2
  10. 'setenv hwconfig tdm' to enable TDM and disable Audio
  11. 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz)
  12. and disable TDM
  13. 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio
  14. 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources
  15. is 11MHz), disable eTsec2 and TDM
  16. Warning: TDM and AUDIO can not enable simultaneous !
  17. and AUDIO codec clock sources only setting as 11MHz or 12MHz !
  18. 'setenv hwconfig 'audclk:12;tdm' --- error !
  19. 'setenv hwconfig 'audclk:11;tdm' --- error !
  20. 'setenv hwconfig 'audclk:10' --- error !
