Hi SH Son
They already arrived Hanoi, Arrival Notice was sent us this morning. we are doing customs clearance. |

Hi SH Son
We did send all documents to Fedex yesterday to do clearance procedures.
It takes 2~3 days to do it, |

Hi Mr. An Tran, Mr. Jacky Chiang and Mr. River Wong,
Factory Engineer, Mr. Michael informed that he couldn't find any issue with boot failed STB, SN : 2149695001202201009341, during 24 Hours Power on/off test(Cold boot).
But we cannot understand your situation.
We tested this defected PCBA without any heat spreader. We tested with only PCBA.
We captured log. You can see the log that we attached in this mantis, https://mantis.cnsbg.foxconn.com/vaas/view.php?id=1506#c10321.
If the root cause is the short 24V and ground with Heat spreader, then there was no log. But we captured log.
@Mr. Jacky Chiang and Mr. River Wong
Could you check attached log ? Can you check what the problem is ? We are suspicious the eMMC part.
After review the log, please leave a comment here.
Best Regards,
SuhYoung YOON |

Hi Mr.SH, Mr. Yoon,
We check with factory site and we may need these samples as below
could you help to provide these? Thank you very much.
No boot:3-5 pcs
No ethernet:3-5 pcs |
|
|
|
Hi EVA.
this case is not from field (end customer, Not used STB).
and we don't have defect samples now. please contact factory first.
I will check again but, hard to find defect samples.
Thanks

Hi Yoon,
In today meeting, you mention about to test EMMC read/write stress test on Boot fail board.(SN : 2149695001202201009341)
For running the script, we need to update the image to userdebug build. But it may change the board situation.
Do you agree us to update it to userdebug image for doing the EMMC read/write test? |
|
|
|
Hi Mr. River Wong,
I agree to update SW for the test.
Currently defected issue doesn't reproduce anymore.
So please update SW and let us know the result.
And could you test with another 4 STBs in your office too ? |

Hi Mr. Yoon,
Thanks. I got it.
We will test one STB in factory (SN : 2149695001202201009341) and 4 other good STBs in our office.
Jerry will help on this test.

For the no Ethernet issue (SKB SN: 2149695001202201009369), the strain gauge test result showed it's normal, please refer to the attached strain gauge test report. |

Performed vibration test 2 cartons *8pcs, no defect found. |

Hi Mr. Yoon,
About the EMMC test,
We use the instruction to read and write DATA Paration.
The size of the file is 1G and the number of tests is 20.
This is the result for a single swan device.
If there is no problem, we will continue to complete the emmc test of other SWAN devices.
Jerry

Hi Mr. Jerry Lin,
Thank you for your support.
We need to test as follow.
1. eMMC R/W Test for 20 time with 1G file as you tested.
2. Power off and on
3. Go to Step 1.
4. We need 25 times of this test.
So it will be tested with 500 times R/W test.

Hi SH Son, S YOON
I update BFX-UA300 2022.05 Production Inspection report as file.
1. LED not working report update Everlight vendor FA report and Corrective action from Fii |

Hi Mr. Yoon,
The factory assisted us in testing emmc reading and writing and the test results are as follows:
1. The test machine is SKB SN: 2149695001202201009369
2. This file is the test result of power on/off 25 times and read/write EMMC 20 times.
3. We checked these test results and found no errors for read and write failures.
For other SWAN devices, we will upload the test results here.

Hi Mr. Yoon,
These are the test results of other SWAN devices (three devices have test logs and another device is verified by SQA and no errors occur during verification, but SQA does not save test logs)
Therefore, no abnormality was found in the EMMC read and write test.

Hi SH Son
Here is '2022.06 Mass production inspection report update action.
1. Suspect this issue relate to Soc_U1 and soldering issue --> Update X-ray U1 & U801 100% ( next build ).
2. Ethernet unstable issue: Update root cause and suspect action from RD.
Pls help review it
Many Thanks

Hi, Rachel
for the Ethernet unstable, as your reported that No long term solution.
I think "PT station implemented the CRC test" is short term solution for the filtering.
my understanding is that chip level(vender side) is Ok but the problem is occurring only at the assembly level.
FII RD confirmed that the delay affects the CRC, to find the solution also.
if FII and Factory define the root cause, please update long term solution as well.
Thanks

Hi Mr. Yoon,
I heard from HW that you want to test image for setting RX delay to 0x60.
I build a test image with RX 0x60 delay in ALT ftp side in /release_by_fxn/swan_test_image/20220916_CRC_RX_0x60_delay/ folder.
But please note, this image can not be used for testing Motorcom phy.
For Motorcomm phy, it will need RX delay for 0. in the feature, we will identify which phy and give suitable RX dealy value.
So, just use this "test" image for your test with realtek phy. |
