因项目需要,我给rk3568加了一个外部RTC:pcf8563,结果打印信息出现: [ 1.158521] rk808-rtc rk808-rtc: rtc core: registered rk808-rtc as rtc0 [ 1.169467] rtc-pcf8563 4-0051: chip found, driver version 0.4.4 [ 1.169669] rtc-pcf8563 4-0051: pcf8563_write_block_data: err=-6 addr=0e, data=03 [ 1.169683] rtc-pcf8563 4-0051: pcf8563_probe: write error [ 1.169715] rtc-pcf8563: probe of 4-0051 failed with error -5 [ 2.302185] [drm:drm_fb_helper_single_fb_probe] Cannot find any crtc or sizes - going 1024x768 [ 4.477163] hctosys: unable to open rtc device (rtc1 不知道是哪里出了问题?之前在rv1126上也是相同的配置,但没有问题。 |
