| Overview | |
| -------- | |
| P1022ds is a Low End Dual core platform supporting the P1022 processor | |
| of QorIQ series. P1022 is an e500 based dual core SOC. | |
| 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 ! |
