‑‑jet_swo_prescaler

In this section:
Syntax
‑‑jet_swo_prescaler=number
Parameters
number

The prescaler value, 1–100, which in turn determines the CPU clock frequency.

For use with

The C-SPY I-jet driver.

Description

Use this option to specify the prescaler for the SWO clock. The CPU clock frequency is divided by the number specified as the prescaler. If data packets are lost during transmission, try using a higher prescaler value.

If this option is not specified, a prescaler value is set automatically. This automatically set value is the highest possible frequency that the debug probe can handle.
