Hi Jerry, Below Is test steps. 1. STB connect hdmi port 1 on TV. 2. Do off STB and TV. 3. change hdmi connection to port 2. 4. ON TV STB is connected on port 2 but is reacting by wrong port command(port 1). "[R] time=2023-04-11 14:20:13 message=<Set Stream Path> 0F:86:10:00" I think that root cause of this issue is that edid is not updating by port reconnection. What is your opinion ? <dumpsys> [R] time=2023-04-11 14:19:44 message=<Standby> 0F:36 [R] time=2023-04-11 14:19:44 message=<Standby> 0F:36 [R] time=2023-04-11 14:19:53 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:03 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:10 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:10 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:10 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:11 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:11 message=<Give Device Vendor Id> 04:8C [S] time=2023-04-11 14:20:11 message=<Device Vendor Id> 4F:87:EC:01:E2 [R] time=2023-04-11 14:20:11 message=<Give Device Power Status> 04:8F [S] time=2023-04-11 14:20:11 message=<Report Power Status> 40:90:01 [R] time=2023-04-11 14:20:11 message=<Give Device Vendor Id> 04:8C [S] time=2023-04-11 14:20:11 message=<Device Vendor Id> 4F:87:EC:01:E2 [R] time=2023-04-11 14:20:12 message=<Give Device Power Status> 04:8F [S] time=2023-04-11 14:20:12 message=<Report Power Status> 40:90:01 [R] time=2023-04-11 14:20:12 message=<Give Osd Name> 04:46 [S] time=2023-04-11 14:20:12 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [R] time=2023-04-11 14:20:12 message=<Give Physical Address> 04:83 [S] time=2023-04-11 14:20:12 message=<Report Physical Address> 4F:84:10:00:04 [R] time=2023-04-11 14:20:13 message=<Set Stream Path> 0F:86:10:00 [S] time=2023-04-11 14:20:13 message=<Active Source> 4F:82:10:00 [S] time=2023-04-11 14:20:13 message=<Menu Status> 40:8E:00 [R] time=2023-04-11 14:20:15 message=<Give Device Power Status> 04:8F [S] time=2023-04-11 14:20:15 message=<Report Power Status> 40:90:01 [R] time=2023-04-11 14:20:16 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:16 message=<Set Stream Path> 0F:86:10:00 [S] time=2023-04-11 14:20:16 message=<Report Physical Address> 4F:84:20:00:04 [S] time=2023-04-11 14:20:16 message=<Device Vendor Id> 4F:87:EC:01:E2 [S] time=2023-04-11 14:20:16 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [S] time=2023-04-11 14:20:16 message=<Give System Audio Mode Status> 45:7D [S] time=2023-04-11 14:20:16 message=<Text View On> 40:0D [S] time=2023-04-11 14:20:16 message=<Active Source> 4F:82:20:00 [S] time=2023-04-11 14:20:16 message=<Menu Status> 40:8E:00 [S] time=2023-04-11 14:20:16 message=<Give Device Power Status> 40:8F [S] time=2023-04-11 14:20:17 message=<Give Device Power Status> 40:8F [S] time=2023-04-11 14:20:17 message=<Report Physical Address> 4F:84:20:00:04 [S] time=2023-04-11 14:20:17 message=<Device Vendor Id> 4F:87:EC:01:E2 [S] time=2023-04-11 14:20:17 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [S] time=2023-04-11 14:20:17 message=<Give System Audio Mode Status> 45:7D [R] time=2023-04-11 14:20:17 message=<Give Device Power Status> 04:8F [S] time=2023-04-11 14:20:17 message=<Report Power Status> 40:90:00 [R] time=2023-04-11 14:20:17 message=<Give Osd Name> 04:46 [S] time=2023-04-11 14:20:17 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [R] time=2023-04-11 14:20:17 message=<Give Osd Name> 04:46 [S] time=2023-04-11 14:20:17 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [R] time=2023-04-11 14:20:18 message=<Report Power Status> 04:90:00 [S] time=2023-04-11 14:20:18 message=<Active Source> 4F:82:20:00 [S] time=2023-04-11 14:20:18 message=<Menu Status> 40:8E:00 [R] time=2023-04-11 14:20:18 message=<Report Power Status> 04:90:00 [S] time=2023-04-11 14:20:18 message=<Feature Abort> 40:00:90:00 [R] time=2023-04-11 14:20:18 message=<Give Device Vendor Id> 04:8C [S] time=2023-04-11 14:20:18 message=<Device Vendor Id> 4F:87:EC:01:E2 [R] time=2023-04-11 14:20:19 message=<Give Device Power Status> 04:8F [S] time=2023-04-11 14:20:19 message=<Report Power Status> 40:90:00 [R] time=2023-04-11 14:20:19 message=<Give Osd Name> 04:46 [S] time=2023-04-11 14:20:19 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [R] time=2023-04-11 14:20:20 message=<Give Osd Name> 04:46 [S] time=2023-04-11 14:20:20 message=<Set Osd Name> 40:47:42:46:58:2D:55:41:33:30:30 [R] time=2023-04-11 14:20:33 message=<Device Vendor Id> 0F:87:00:E0:91 [R] time=2023-04-11 14:20:33 message=<Device Vendor Id> 0F:87:00:E0:91 |

Hi Wooshin, SWAN can not get edid info in standby mode. Because it has a power switch to control HDMI on/off. I remember that SWAN can not be turn on when TV was turned on or TV HDMI port was changed. Has the behavior of CEC been changed ? I can add some protection to prevent SWAN device from being opened. Jerry |

Hi Jerry, If you have some solution, add it. thanks. |
|

Hi jerry, Do you have any update ? |
|

Hi Wooshin, Please help to download the test F/W from ALT Server. The download link is : /release_by_fxn/swan_test_image/mantis1700/usb_bfx-ua300_V19.536.19_SD.zip My modification is as follows: 1. Re-read the CEC physical address from edid when the device is turned on. 2. Stop receiving CEC message when the device is in standby mode. Jerry |

Hi Wooshin, I check with the log. I found that TV send "<Active Source> 0F:82:00:00" to device. This is very strange.

Hi jerry, We are testing in SAMSUNG TV and test's result is inconsistent. If I would have, I will share. Thanks. |
|
|
Hi jerry, There is side effect. It is same with SAMSUNG TV and LG TV. < Test Steps > 1. Off STB and TV 2. On TV 3. STB keep off ( should be ON by CEC ) Thanks. |
|
|
Hi Jerry, Do you have any update ? Thanks. |
|
|
Hi Wooshin, We have discussed this issue and provided test FW. But it doesn't seem to improve this issue. 1. The CEC physical address cannot be updated. Because the EDID informatin cannot be updated in standby mode. This is a limitation. jerry |
