I got simple audio application base on power on self test. Till now I do not have this kind of problem with it but lately it looks like audio codec is not properly configured or there is same problem with output analog section. I am using EZKIT BF548
In debug, with 100B on, it start to failed, I can hear distortion, all the time now before it was always perfect.
Same is when I run application in loader option and jtag is not used but is connected to KIT and to laptop on other side.
When I disconnect jtag from one side, laptop for example, even without reset, everything is start to work properly.
It looks like I have maybe ground problem, shall I used same separation between laptop and jtag?
