| Summary | 0001451: [Smart3][UHD4][BTF] About VoC ( no input signal ) | ||||
| Description | Hi Kerwin For FXN models, VoC is relatively high with "no input signal" issue . ( Smart3 and UHD4 (AOSP 10) ) In other words, it is not possible to lower the VoC value without solving "no input signal" issue. Attached is the VoC logs(24)about "no input signal". please review the contents and write the clues in the log. and I have attached the no_input_signal.xlsx file. please help brent for interpretation. (Note) In particular, if there is no clue, please give us your opinion on how to guess (fix) the cause in the future. (For example, add more logs to the suspicious part.) We also need to inform SKB of how to improve this issue. Thank you YK.Jung | ||||

Hi Kerwin Please check one more VoC log attached here. Strangely, only plugout events are occurring. =========================================== [ 0.635429] hdmitx: system: plugout [ 91.070854] hdmitx: system: plugout [ 91.072599] hdmitx: amhdmitx: cable plugout, set hdev->hpd_lock to 1 [ 445.135412] hdmitx: plugout in sleep. stay hdp state [ 1331.817347] hdmitx: system: plugout [ 1331.818801] hdmitx: amhdmitx: cable plugout, set hdev->hpd_lock to 1 [ 1354.707129] hdmitx: plugout in sleep. stay hdp state ======================================================= Please analyze this situation. Thank you YK.Jung |

Hi YK, I have no idea why there was 'plugout' events in dmesg.txt. The only way to see similar message is not to connect HDMI cable. The HotPlugDetection pin is an input pin for STB. Please check handler in file below: common/drivers/amlogic/media/vout/hdmitx/hdmi_tx_20/hw/hdmi_tx_hw.c static irqreturn_t intr_handler(int irq, void *dev){ .... if (hdmitx_hpd_hw_op(HPD_READ_HPD_GPIO)) { pr_info(HW "last hpd state is high in sleep. go to plugin\n"); dat_top_in_locked = 0; dat_top = 0x80000002; } else { pr_info("plugout in sleep. stay hdp state\n"); dat_top_in_locked = 0; goto next; } ...... |
