F103 SWO Speed

SWO speed seems to be 64Mhz on STM F103, anyone noticed the same? It gave me trouble after mbed update, since it was previously 72Mhz and SWO data went corrupted.

Hi Alex,

Which version of Mbed you used before and which version of Mbed you update to?

You can override below system clock configuration in mbed_app.json to make SWO runs on 72Mhz.
