However, some of the SoC models can only operate at a maximum speed of 1 GHz. Previously, the boards with lower-speed grades were running at overclocked speeds, leading to kernel complaints about unsupported configurations. To resolve this issue, the operating speed has been decreased to the maximum allowable value across all Verdin AM62 board variants. As a result, there is a regression in overall boot time, increasing by around 200 milliseconds for the faster SoC variant.
