HI Jason when the resolution is auto, there is no issue. BFX-AT100_20240102-125734_auto_ok.zip After setting it to 2160p , I reproduced the issue. BFX-AT100_20240102-130002_2160p_fail.zip Note : The issue reproduction point is to press the power button when the resolution changes. Please check the issue. Thank you YK.Jung KakaoTalk_20240102_130731374.mp4 (22,379,911 bytes) |

Hi Younkwang, I can use our 2K monitor(resolution choose "Full HD 1080p") to reproduce, and audio outputed from monitor but black screen. But I can't reproduce using our sharp 4K TV. Do you have the same issue on non-4K monitor or TV? Thanks~ Sam |
|
|
Hi Sam When testing on a 1080p monitor, the issue is being observed when testing after setting the resolution to 1080i. And since it is easy to reproduce the issue, SKB expects that it will be solved quickly. Please update the progress around 5 pm every evening Thank you YK.Jung |

Hi Younkwang, I find that it probably because => When change the resolution, the device will change it first and display a confirming dialog. But if user quickly press Btv button to enter sleep mode without confirm the dialog, it seems M/W or Launcher will set back the resolution after sleeping. the log: 01-04 15:24:31.546 3522 5027 I SystemControl: setSourceOutputMode mode:displayoff 01-04 15:24:31.745 3522 5027 I SystemControl: setSourceOutputMode mode:1080p60hz This seems will cause the issue. Please check with M/W or Launcher team and maybe they need to set a block to sleep before confirming the dialog. Thanks~ Sam |

Hi Sam It is difficult to say that it is an issue of MW/Launcher with this content. First of all, the issue is being observed only in FXN BFX-AT100 And if the resolution is auto, there is no issue. Please analyze it further. and I'll check with the INTEK Smart3 box Thank you YK.Jung |

Hi Sam When I check, the major difference is 1) Enter the '편성표' key for more than 5 seconds 2) enter sleep when the screen blinks * BFX-AT100 : a black screen is displayed here at sleep state * BID-AT100 : no input signal is displayed here at sleep state 3) wake up and exit key * BFX-AT100 : black screen * BID-AT100 : video is ok When entering the sleep state, no input signal should be displayed. Looking at the log, it seems that HDMI display setting are made after entering the sleep state. Please check it Thank you YK.Jung |

Hi Sam This issue have to be resolved by today Please update the progress by 13:00 (KT) Thank you YK.Jung |
|
|
Hi Younkwang, The root cause is : when the resolution confirm dialog is unfinished, it will reset resolution after standby mode. this will cause HDMI driver status partly reset like as wake up mode. And then when wake up the device, the black screen will occur due to the abnormal HDMI status. Now I try to fix it by bypass "reset HDMI driver status as wake up mode" and build a test FW. When it done, I will upload for you to verify. Thanks~ Sam |
|
|
The test FW is : /release_by_fxn/smart3_test/20240105_mantis1856/usb_bfx-at100_V15.541.528.zip Please use it to verify, thanks~ Sam |
|
|
Hi Sam I tested 5 times, but there is no black screen issue However, after wakeup, resolution issue is observed. ( attached picture ) please check it Thank you YK.Jung |
|
|
Hi Sam Please update the progress Thank you YK.Jung |
|
|
Hi Younkwang, I am still figuring out the root cause. |
|
|
And even we have a solution, I don't think it could be quickly applied without lots of tests. Thanks~ |
|
|
Hi Sam So what are you going to do? Are you saying that you can't solve it within the schedule(today) ? Please update the progress within 2 hours Thank you YK.Jung |
|
|
Hi Sam I just had a brief meeting with SKB This issue is currently Major defect at SKB QA If this issue is not resolved by 5 p.m(KT) today, FXN model' Next BMT will be fail Please solve it quickly Thank you YK.Jung |
|
|
Hi Younkwang, Currently, there will be a quick command of changing back the resolution after standby(because no confirmation of resolution request). And I find that it kindly cause the issue, so I try to add delay for changing back the resolution. If this method works, I'll feedback to you. Thanks~ Sam |
|
|
Hi Younkwang, Please use the test FW to verify: release_by_fxn/smart3_test/20240108_mantis1856/usb_bfx-at100_V15.541.528.zip I add delay to reset the resolution back after entering standby mode. Thanks~ Sam |

Hi Sam I tested your test FW The issue of black screen is being observed. Did you test with this FW? ======================================================== [ro.product.build.version.incremental]: [15.541.528-20240108] [ro.system.build.version.incremental]: [15.541.528-20240108] [ro.vendor.build.version.incremental]: [15.541.528-20240108] [ro.vendor.build.version.release]: [10] [ro.vendor.build.version.sdk]: [29] [ro.vendor.fw.version]: [15.541.528] [ro.vendor.vasott.version]: [k000b-541r529c1856_SD-20240108] ======================================================== and the power button for wakup and the operation looks delayed, this is also a problem Please check it again. Thank you YK.Jung |
|
|
Hi Sam Please update the progress If you can't solve it by today, please give me the schedule again until when it can be resolved. Thank you YK.Jung |
|
|
Hi Younkwang, I am still working on it, and I still don't have a clue to solve it(already try many methods). So... there is no schedule now. |
|
|
This is about SystemControl service. I think you can also let Amlogic to check it, since they should be familiar with it. |
|
|
Hi Sam This problem is now being observed only in FXN model. ( INTEK does not have this issue. ) If you want to request SoC review in this state, we have to inform the SoC log of the evidence. Can you send me this information? Thank you YK.Jung |
|
|
Hi Younkwang, The evidence is: 1.It's about SystemControl 2.We just follow Amlogic's advice to display off/on but the display on has the issue. 3.If MW or Launcher could complete setting resolution first instead do it when standby mode, I think this issue could be resolved. You can see in the previous logs: 01-04 10:42:43.324 3522 3718 I SystemControl: setSourceOutputMode mode:displayoff 01-04 10:42:43.643 3522 3718 I SystemControl: setSourceOutputMode mode:1080p60hz 01-04 11:10:54.275 3522 3718 I SystemControl: setSourceOutputMode mode:displayon And when displayoff or displayon, we just follow Amlogic's advice to set device nodes: displayoff: set /sys/class/amhdmitx/amhdmitx0/phy 0 set /sys/class/amhdmitx/amhdmitx0/stop_hpd 1 displayon: set /sys/class/amhdmitx/amhdmitx0/stop_hpd 0 But somehow it's display the black screen. (I think the cause is the status is abnormal when setting resolution in standby mode) And I also try to add: sleep again when this situation: (logcat20240109_DisplayOffFirstBlackScreen.log) 01-09 10:41:28.974 3514 5369 I SystemControl: setSourceOutputMode mode:displayoff 01-09 10:41:29.187 3514 5369 I SystemControl: setSourceOutputMode mode:1080p60hz 01-09 10:41:34.195 3514 7572 I SystemControl: setSourceOutputMode mode:displayon 01-09 10:41:34.195 3514 7572 I SystemControl: write /sys/class/amhdmitx/amhdmitx0/phy, val:0 end (display off) 01-09 10:41:34.371 3514 7572 I SystemControl: write /sys/class/amhdmitx/amhdmitx0/stop_hpd, val:1 end (display off) wait 5 sec... 01-09 10:41:39.377 3514 7572 I SystemControl: write /sys/class/amhdmitx/amhdmitx0/stop_hpd, val:0 end (display on) 01-09 10:41:39.391 3514 3583 I SystemControl: setSourceOutputMode enter, 1080p60hz, 1 But the issue still occurs. I think we need Amlogic's advice for this scenario. Thanks~ Sam |

|
|
Hi Sam First of all, I reported to AML Kor, but I'm not sure when I can get feedback from AML Kor. And if we check this issue, this issue has been observed in FW a long time ago. I know that HDMI related modifications were implemented through Taiwan AML FAE. Please discuss this issue with Taiwan AML as well. Thank you YK.Jung |

Hi Sam It has been confirmed that the basic operation is ok. - After wakeup, the black screen issue has been resolved - After wakeup, incorrect resolution setting issue has been resolved the "no input signal" should be displayed on the TV after STB enter the sleep state When tested with this FW, "no input signal" is not displayed at TV after entering the sleep state. Please check it Thank you YK.Jung image-2.png (38,783 bytes) |

Hi Sam I have discussed with SKB now. Please commit the current code status and let me know when you're done And I will make one more JIRA The JIRA is about the following issue "no input signal" is not displayed at TV after entering the sleep state Thank you YK.Jung |
|
|
Hi Younkwang, done~, the commit is: 2024-01-10 17:21:25 | sam.cy.yang@mail.f.. | 3199c8a74 | vendor/amlogic/common | [BPM-27423] 1856: fix black screen issue when resolution is changed Thanks~ Sam |
|
|
Hi Younkwang, I have a test FW for the "no input signal" issue now. If you make a new JIRA, please let me know. So I can past the FW path to it. Thanks~ Sam |
|
|
Hi Sam. Please use BPM-27701 prefix. https://jira.skbroadband.com/browse/BPM-27701 Thank you. Kim |
|
|
Hi Sam Please update the progress on the "no input signal" by 13:00 (KT) https://btracker-cns.fii-foxconn.com/vaas/view.php?id=1856#c14936 Thank you YK.Jung |
|
|
Hi Younkwang, Please use this test FW to verify "no input signal": "/release_by_fxn/smart3_test/20240115_mantis1856/usb_bfx-at100_V15.541.528.zip" Thanks~ Sam |
|
|
Hi Sam QA reviewed the FW you sent me. "/release_by_fxn/smart3_test/20240115_mantis1856/usb_bfx-at100_V15.541.528.zip" During the test, "no input signal" is observed even after the STB wake up. It does not always occur, but it occurs once every 5 attempts. Please check the FW again Logs and related information will be updated further tomorrow Thank you YK.Jung |
|
|
Hi Sam I tested the test about three times In the last state, STB is woken up, but "no input signal" is observed on TV. Reproduction is not difficult. Additionally, SKB is complaining to me about this issue. I ask you to solve it quickly. Please check it Thank you YK.Jung |
|

Hi Younkwang, Please use this test FW to verify: /release_by_fxn/smart3_test/20240117_mantis1856/usb_bfx-at100_V15.541.528.zip I fix it by: 1.turn off display again when resolution set in standby mode. 2.add mutex to avoid setting display on and setting resolution requested in the same time. Thanks~ Sam |
|

Hi Sam QA review results Black screen issue after wake-up occurs except for automatic -> 2160P ( After the wake-up, the screen is black and audio is ok ) Attached is the QA test result ( video and log ) , Please check it again and did you test it with this FW ? Thank you YK.Jung 이슈재현.mp4 (10,157,219 bytes) |

Hi Younkwang, Please verify with the test FW "/release_by_fxn/smart3_test/20240125_mantis1856/usb_bfx-at100_V15.541.528.zip" We try to fix the issue by: 1.add mutex for display on/off and resolution setting. 2.display off again after M/W setting the resolution in standby mode. 3.avoid setting resolution within too short time(1 second) after waking up the device. We pass the test for 30 times with this FW. Sometimes it will take a bit long time for light on the TV. Thanks~ Sam |
|
|
Hi Sam. Our QA tested your test FW, it seems ok. Please wait the commit your modification. I will let you know when the ready to commit. Additionally, please check if this modification should apply to ATV12. Thank you. Kim |
|
|
Hi Sam. Please update the progress of my comment. "Additionally, please check if this modification should apply to ATV12." Thank you. Kim |
|
|
Hi Sam This issue should be resolved in OS12 UI542, by early next week. Please update the progress. Thank you YK.Jung |
|
|
Hi Sam Please update the progress Thank you YK.Jung |
|
|
Hi Sam Please solve this issue which is also observed in UI542 by this week. Thank you YK.Jung |
|
|
Hi Younkwang, I am checking it. Thanks~ Sam |
|
|
Hi Younkwang, I test for many times in ATV12, but the issue doesn't occur. Furthermore, it seems that the resolution can't be changed. I remember you said that in ATV10, I should checkout to 541r528 code base for testing. Should I also checkout to some code base for testing in ATV12? Thanks~ Sam |
|
|
Hi Sam The QA team checked this issue several times, but as you said , there is no issue at ATV12 I'll let you know after I check more. Thank you YK.Jung |
