TMS320DM642: The compiler cannot continue running

Hello,

There is not enough information provided to investigate this issue.

Please see the below article regarding what details are needed.

Thanks

The main problem is that during runtime, the program checks the chip, can connect to it, but cannot run it

It looks like you are using a very old version of CCS. CCS 3.x or earlier. Please note that this version is unsupported.

That said, your issue is not related to the compiler. It looks like you have an executable you are loading to the target and I see it successfully load and reach the entry point of the program. Your first video it just runs with no other result. Your second video it runs with output. I assume the second video is correct. 

As to why it does not run correctly in the first video, I can't say. You will need to step through the code and see where it fails. There does not appear to be any issue with CCS itself here that I can see.

It seems that the TMS320DM642AZDK6 program cannot be burned in at present. How can I troubleshoot this issue

What are the common reasons for this kind of burning not going in?

I'm not sure. I will bring this thread to the attention of the device experts for further comment.

Hi,

I’ve assigned your query to the concerned expert. Please note that responses may be delayed due to the Christmas and New Year holidays. Please feel free to ping this thread if you don't receive a response by Jan 1st week

Thanks for your understanding.

There are a large number of possible causes for what you are seeing. 

In this instance, it sounds like the device sometimes works. This could be due to voltage supply issues, bad solder connections, etc.

This one has not been burned. During the burning process, the corresponding burning address for the chip could not be found, which prevented the burning process from continuing. It simply doesn't work at all.

How many failures have you seen out of how many devices? 

Are you employing ESD safe handling practices? ESD could damage the part. 

Were/are the  power rail voltages to spec?   

Are pins being driven while the devices is powered down? 

Was the non-working device tested on another board? 

--Paul 

1、Out of 400 tests, 28 BGA devices failed to write the addresses. As shown in the attached video;
2.  On the same board, after replacing this chip, normal writing can be performed.

Have you tried repopulating a known good board with one of the devices that had issues?    What were the results?
