I update check list. |
|
|
Hi SB, As per discussion in weekly meeting, I will waive the IR response time test since there is no layout changes for IR circuitry in DVT build. Also, the 3 wavelength test should already be covered in IR range test report. Please check the IR range test w/ desk lamp on. |
|
|
thank you Sean, the IR test is completed. |
|
|
Hi SB Update power on/off, Accuracy, Ripple, crystal and DDR stress report. Thanks. |
|
|
Hi Jim, Sean Thank you very much. I have a question. there is no TXC report at EVT. will you make board with Xtal of multi vender? |
|
|
Hi SB, Update the button test report. Thank you. |
|
|
Hi, Fu-chiang thank you for your report but, I have a question. according to your report, I think It is just SQE test. there are no power level of push button, number of push count, and cycle time between push button and push button. (normally, button test is power : 2.5N, no :100,000, and cycle 1Hz) |
|
|
Hi SB, This report is provided from ME and the test result is pass. Please see the attached file. Thank you. |
|
|
Hi Sean, Fu chiang Thank you for the test report. 1. but according to your report, the model name is still "T99X171.00". Please change to BFX-AT100 and update again. 2. There is no power level of this report (only cycle and speed) 3. There is no picture of before and after test. the report is just explained Pass by text. |
|
|
Hi SB, Update botton reliability test report with correct mode name. Thank you. |
|
|
Hi Fu chiang, thank you for update but, only model name is changed. I want to know the below information and please update - There is no power level of this report (only cycle and speed) - There is no picture of before and after test. the report is just explained Pass by text. |
|
|
Hi SB, Sorry for updating many times. Please see the attached file. Thank you. |
|
|
Hi Fu-chiang Thank you for your support. Good job |
|
|
Hi SB Update USB 2.0 and Ethernet SI report |
|
|
Hi SB Update noise report |
|
|
Hi Jim. thank you for update 1. but the ID name is T99X171T00 in all your report. please change the BFX-AT100 2. According to FULL Speed report, I cannot read the value of EOP width (see below picture) fullspeed.gif (7,617 bytes) |

|
Hi SB, This is DCDC test from vendor that the test fail in EVT build. Due to the cut-off point was not reserve for vendor to test power efficiency, the test results were fail. This DVT build we only SMT on power IC components for vendor to test power efficiency, the test results are pass. Please see the attached file. Thank you. |
|
|
Hi SB, Update LED leakage test report |
|
|
|
|
|
Hi Sean. thank you for your update. 1. but the LED leakage test report format is not good. there is no model name. sw version and so on. 2. some pictures and sentence of your report are cut off partially. 3. please update test setup detaily. according to your report, you test at dark room. but in the picture, it is no dark room. |
|
|
Hi Fu-chiang thank you for updating DCDC report. according to your report, 1. there is no critera of Ripple, load transient and bode plote |

Hi SB Update USB 2.0 and Ethernet SI report again |
|
|
Hi SB, Update DCDC power report. Add more critera of ripple, load transient and bode plot. Thank you. |
|
|
Hi Fu chiang according to your report of DCDC 1. The ripple spec is right. normally, ripple is specfied by % not value. and the ripple is so big. (VDD_EE's output voltage is 0.82 and it's ripple Vpp 0.2V.) If it is true, the AMLOGIC IC may be hangup. 2. There is no result value of ripple, load transient, bode plot. there is only waveform. |
|
|
Hi SB, Update the DCDC power report. Checked with vendor for spec, the spec had been updated. Thank you. |
|
|
Hi Fu chiang according to your report, there is no min/typ/max of ripple spec. If someone see the ripple result, they may confuse that the result of ripple is pass or not. please add min/typ/max at ripple spec ripple table.gif (25,964 bytes) |
|
|
Hi SB, Update min/typ/max of ripple spec. Thank you. |
|
|
Hi SB, Update min/typ/max of ripple spec. Thank you. |

Hi SB Update EMMC stress test (Data read, write, erase test) |
|
|
Hi Fu Chiang. according to your report, I don't understand Vmax-Vmin. 0A value is over spec, 2A is in spec. See below table |

Hi Jim. thank you for your report |
|
|
Hi SB, Vmax-Vmin is mean Vpp for vendor test. In order not to confuse, I remove all Vmax-Vmin value and update again the report. Thank you. |
|
|
Hi. Fu chiang Thank you for your report. good job |
|
|
Hi SB, Update USB3.0 TX test report. For the USB3.0 RX test, AML still don't support this test. Need AML RD site to look into this issue. |
|

Update the status for the rest of test items. 1. Emmc, DDR aging test (replace to HWQA Aging report) - The testing was completed and passed the spec. The final HWQA report will be released by 6/19 2. DDR SSQ test - Still wait for Samsung to update the complete schedule 3. HDMI/HDCP. - The HDMI & HDCP test are completed by Simplay Lab. The report will be release by 6/24 4. Thermal surface, derating - The test was completed. The temp. of bottom case is out of spec. but result seems something wrong. (The outside temp. of housing is higher than inside temp. for both top and bottom). Our QA team is checking their test environment. (see test report in attached.) |
|
|
Hi SB, Update LED leakage test report. |
|
|
Hi SB and Philip, For the thermal test result, our QA team confirmed that they record the wrong thermal result for the inside and outside housing surface. Please see attached for the updated thermal report(BFX-AT100 thermal measurement report 20190606). The bottom temperature was margin fail @50 deg. C. In addition, we also checked with the EVT test report and found out that the environment setup between EVT and DVT HAS a little bit difference. In EVT build, that is in very early stage, the test condtion is 4K video local playback by using VLC and using iperf3 to do the throughput test (D/S: 50MBytes, U/S: 50Mbyte) (refer attached Thermal test report for T99X171T00_2019-04-12.pdf) In DVT build, the test condition is 4K video playback by using Youtube. We found the power consumption in DVT build will be higher than EVT about 0.11~0.21W. Please see attached power consumption sheet "0530_5pcs" and "0630" for the comparison (BFX-AT100 thermal measurement report 20190606). Anyway, compare with EVT and DVT test result. We think the environment setup tolerance and power consumption difference would be the root cause for the fail. Would it be possible that we can negotiate with SKB to accept the bottom case temperature? As you know, the temperature raising < △t15 ℃ is very strict and user will not be able to touch bottom case normally. |
|
|
Hi Sean. which adatper is used at thermal measurement? If you use SGnetwork adapter at thermal test, please test again to use editech adapter |
|
|
Hi SB, The adapter which we used for thermal measurement is SGnetwork. However, the power consumption we measured is at DC side instead of AC side. So, I think that there should be no difference if we change adapter to Editech. |

Hi SB, We have a board for reliability test whichc is for operational temp. range test. Due to we change new FW version from r13 to r39, but the DUT cannot login with original permission code. The TV screen showed ID invalid. Could you please help to access the permission code available? mac address: ec:5c:68:1d:bd:1c Birth date: 717086 USER_SERVICE_NUM: 100601048215 Thank you. |

Dear SB Please refer DDR4 SI report |
|
|
Hi Jim thank you for your report. 1. but, why ony one DDR U503 is measured? why do not test U504. 2. There is no spec value of tck(ave) (clock cyle time) ddr_ssq_spec.gif (36,538 bytes) |
|
|
Dear SB The Samsung reply as below: They can only choice one location to measure from the same size of DDR The empty part here is no spec. So the result is OK. |
|
|
Hi SB, according to your report, wake up time of DVT board with standard google TV FW version wake up time is under 2s. but, wake up time of EVT with standard google TV FW version was under 5s and, the result of active standby wakeup and passive standby wakeup are the same 2s. is it right? ==>Yes. EVT and DVT board are both the same wake up time that needs about 5 sconds to light on TV and under 2 seconds reply on console message. |
|
|
Thank you Jim. |
|
|
Hi Fu chiang. In your report. passive standby wake up time is under 2s. what is right? 2s? 5s? |

Hi SB, The correct is as report shown, wake up time is 2 seconds. Thank you. |
|
|
Hi Fu chiang SKB's criteria of wake up time is a period from push key of RCU to Display screen at TV |
|
|
Hi SB, If the display screen at TV is as wake up time, the wake up time needs to change to about 5 seconds. The update report is as attached file. Thank you. |
|
|
Hi Fu Chiang According to your report, is it ok? (see below picture) and, please add this result to the report "T99X171T00 V015_Power consumption_20190521_EVT_DVT FW_V2" and update it at mantis wakeuptime.gif (13,739 bytes) |
