STM32L476 + ST25RU3993

[Alex_tw]

When I tried to start my device using the sample code provided by the manufacturer, I received the error messages "SetBaseFrequency not working" and "PLL not working". I have confirmed that the device's crystal is functioning properly and the MCU is working normally. What could be the possible reasons for this issue?
