hello_world to a nexys 4 DDR

I've just created a project which allows me to read message hello world but even if i've created block design correctly, when i launch SDK then  a message saying "Unable to stop Microblaze,Microblaze is held in reset" appear on my computer. How can i solve this problem?Any help would be kindly appreciated.

 

Best regards

@pmandarino2512 

A few hints: 

 

1. check the polarity of the resets - acitve low/high. this is the most common case. 

2. Some DDR problem. Edit your link script so it runs hello world from your BRAM. See what happens

3. Frequency too high for the microblaze/timing constraints
