S32K341 Crystal oscillator power is not applied.

[Masaki_Mori]

I finished checking the operation using S32K3X4EVB and made a per_pin board for S32K341. I wrote the S32K3X4EVB firmware, but power is not applied to the crystal oscillator circuit.

Hello @Masaki_Mori,

Can you share the schematic? If not here, please create a ticket.

Have you checked the power supply?

Can you load the project to the S32K341 MCU on that board?

Best regards,

Daniel

I have not created the schematic. Application of power has already been confirmed. It seems that the project is being written to the S32K341 . A 256Hz self-oscillation output can be seen at the MCU reset terminal PTA05.

HI @Masaki_Mori,

Can you disable Run on reset in the debug configuration and step through the code from the reset vector after the image has been loaded? Is there is Fault exception detected?

Regards,

Daniel

Hi, Daniel

I made a mistake in attaching the emitter and base of the transistor. This problem is resolved. Thanks.
