TMDSEMU560V2STM-U: Product quality problem identification

Hello,

SB45958: Both indicator lights are off. Unit does not look powered. This probe could be dead

SB46011 and SB45959: USB light is RED while MODE light is BLINKING GREEN. This means the probe is powered and booting up. It should take ~20 seconds to finish booting up and then the MODE light should turn SOLID GREEN. If it never turns SOLID GREEN, then there is some issue with the boot up.

You may want to suggest putting the device into safe mode and follow the steps suggested by the Blackhawk engineer in the below post:

The attached documents are also very helpful:

SB46012: This probe looks good. The issue is elsewhere. What is the exact error you get when the connection fails? What is the results of the JTAG connectivity test?

Hi Ki,

Thank you for your help.

My customer is looking for a test environment. The new test results may be a few days later. I will update the post as soon as possible.

Thank you again.

Best regards,

Hi Ki,

Thank you for your help.

My customer has updated the test results. Please help determine whether the product quality problem is caused.

Best regards,

It looks like SB45958 is bad and should be returned. Please contact the vendor you purchased it from.

SB46011 is confirmed good

SB45959 - I believe this is confirmed good also? Is this correct?

SB46012 - it looks like the probe may be good but the issue is elsewhere. Please have the customer run a JTAG connectivity test (see my last post on how) and post the results here.

Thanks

Hi Ki,

Thank you for your help.

I get feedback from customers.

"SB45959- we tested it according to the way you provided and it was really bad. We have video evidence. We've tested it several times and the results are the same.
SB45958- We bought it from our website.
SB46012 - dev.ti.com/.../node ，When I went in, it was blank, with no reference articles"

In the word doc, the comment was "Operation as above, as before USB MODE red light / green light flashing". This means that the probe is booting up. This was also the case for SB46011, which works. Does SB45959 never fully boot up? Is that the issue?

Is there a contact for returns for items purchased from our site?

SB45959-There is one unsuccessful boot counter inside the device so that you can plug and unplug more than 10 times for 3 to 5 seconds each time and be in safe mode. When you enter safe MODE, the MODE indicator will be red，The mode light is still blinking green.
In the video, SB46011 and SB45959 operate. SB46011 can automatically enter the safe mode, but SB45959 cannot enter the safe mode no matter how hard we try.
SB46012- The page as shown below is not successful.succeeded is not displayed.

SB46011 seems to boot up and enumerate successfully (when both LEDs turn GREEN). The other seems to never boot up successfully. After several (unsuccessful) boot up attempts, it should try to boot up in safe mode (blinking RED MODE LED). If this never happens, it could be a bad probe. Note that you may need to have several boot failure in a row before the probe tries to boot into safe mode. I assume the customer tried many times. Assuming that is the case, they may want to contact Blackhawk support for further assistance (this issue is beyond my scope of expertise).

Hi Ki,

Thank you for your help.

Let me summarize the information:

Sb45958 is bad and can be returned,right?

SB45959-Is it good or bad? Is it possible to return or exchange goods?

SB46011- Is it good or bad? Is it possible to return or exchange goods?

SB46012-Is it good or bad? Is it possible to return or exchange goods?

Please clearly inform the judgment result so as to help the customer go through the return and replacement process.

Thank you.

It appears so. Customer may want to confirm with Blackhawk support about this.

This seems to be working. I don't see any issue here. The probe boots up successfully and both lights turn solid green. This is good.

Zhonghui Xu said:

SB46012-Is it good or bad? Is it possible to return or exchange goods?

I'm not sure. That probe seems to boot up ok but CCS is having issue communicating with the probe. I suggest the customer try rebooting the PC and plug in the probe in a different USB port directly to the PC (no hub) and try "Test Connection" again.

Thanks

Hi Ki,

Thank you for your reply.

About SB46012- We are all USB straight plug, not through hub splitter, we tried all the methods you mentioned. Also changed different computers to test, the results are the same。

Please have the customer try testing using the BH560v2 configuration tool. The probe may be in safe mode and you can also use the tool to clear safe mode.

The document for the BH560v2 config tool is the Bh560v2Config-UG-05.pdf document in the zip I attached earlier.

Hi Ki,

Thank you for your patience.

My customer feedback:  the engineer returned to work yesterday. When he was preparing to test the equipment, he found that the wiring was loose. If you continue to test according to the figure, the loose wire will definitely fail the test. The engineer would like to ask whether the box can be removed. If the box is removed and the row of wires is inserted, whether the warranty will be returned after the test.
The engineer said that if the box is dismantled, it may be connected, but the previous problem may not be solved. He was afraid that if the box is dismantled privately, there will be no warranty.

This could be the case. I don't have any knowledge on things like warranty or returns. It would be best to contact Blackhawk support directly.

Hi Ki,

Thank you for your help.

I'll sort out the previous replies.

Sb45958 and sb45959 are faulty and can be returned or replaced.

Sb46011 is good and does not need to be returned.

Sb46012 cannot be tested and determined(Is there any other test plan?).

right?

Are there any maintenance suggestions for the faulty parts?

Thanks a lot.

Best regards,

Hi Ki,

Thank you for your patience and help in a long time.

Got it,Thanks again.
