What is this warning about in '02 - Husky Triggers'

1

Hi!

I was revisiting the ‘02 - Husky triggers’ notebook to refresh something about a problem i had…

I upgraded the framework to version 6 and I don’t remember if this warning was always there, in the fifth cell, just the first one after configuring the Husky and the SAM4S targer this warning is shown (ChipWhisperer Scope WARNING|File TraceWhisperer.py:1370) Coudln’t achieve exact desired frequency (105054290.771484); setting to 104933389.663696 instead.

But that speed is not close to the speed being configured, I wanted to know what is triggering this alert, but I wasn’t able to fing any information about, beyond the fact that the function is related to the speed of the SWO protocol…

The UART trigger module uses a clock that’s higher than the baud rate; that’s why you’re seeing a higher number which appears to be unrelated to the baud rate.

The warning is just a warning.
