TMDSEMU560V2STM-U: The Device is not working

Hello,

Junfeng Jia said:

The USB LED is always red. never turn to green. It cannot connect to my computer or CCS. The mode LED is always blinking green. So, It failed at the beginning. It never works.

Basically the probe has power but has not enumerated and is stuck booting up.

You can try going into safe mode (check the user's guide for the debug probe) to troubleshoot further. I would also suggest they contact Blackhawk support if if you wish to troubleshoot further. 

Thanks

There is no link in the line. 

 (check the user's guide for the debug probe)

I searched "TMDSEMU560V2STM-U user guide" . I did not find the user guide for TMDSEMU560V2STM-U.  Could you please give me the link of the user guide?

Please see:

https://www.blackhawk-dsp.com/documentation/product-documentation#BH-USB-560v2

It is part of the installation guide. You need to be logged into your Blackhawk account

I run "Blackhawk XDS560v2 Configuration Utility" with the device plug in. the utility can not detect the device:

the device usb led is always red. and the mode led is always blinking green. looks like it never finish the booting. So it did not enter safe mode or other mode. 

My computer (in control panel) can not detect the device neither.

Based on Blackhawk documentation it appears it should automatically enter safe mode after several failed boot attempts.

If you wish to troubleshoot further, I suggest working with Blackhawk for further assistance.

I did 10 times power cycle of the device. The intervals are about 40 seconds to 60 seconds. Then wait 30 minutes. it still was booting. USB LED is solid red; Mode LED is blinking Green. Looks like it never enter any mode. From my first use it to now, it has been in this situation.
Could I ask a replacement?

I can't answer any questions regarding the replacement process. I will defer to others (whom have been notified of this thread).

They asked me to come here to get that you approve that:

this device exhibit a possible non-conformance to specifications.

we did a lot of effort, it still can not work. So,  it exhibit a possible non-conformance to specifications,

Hi, Steven,

Thank you for taking the time to talk to me.

I just understand why customer support center let me come here:

They need an answer for the following simple question, and only TI experts in the E2E forum have the authority to answer the question by TI new return/replacement rule. The question is:

Does the device that we talk about above exhibit a possible non-conformance to specifications?

If the answer is “yes”, then I can go back to the customer support center to continue my replacement application.

When you answer the question, please take the following two facts in count:

• I paid for a brand-new device in my order. The device was not working at first use, it never works. And the device is still under warranty.
• We put a lot of effort to test it and tried to make it work here. But the device still doesn't work.

Thanks!

Best regards,

Junfeng
