  • hello I also have this problem. Have you solved it?
3

it looks like your DMA block sanity issue.
More info can help.
Ensure your naming is align with your block design

There’s no mention of any DMA and the problem for the original poster happens when downloading the overlay.

@baiyueguang994, as this thread is very old, please open a new support post and provide as much information as possible.

I misread. Agree the below code indicating pl serivice is time out so DMA is not the reason it is led to timeout.

I can’t say I solved it, because I do not fully understand how the issue resolved itself, but I noticed I was not including the top level .tcl file. When I did, it starting working.
