DUT_PDLL_XTAL_TRIM_FREQ_CAL_NOT_CONNECTED

When trying to write in PLT, the following error occurs.

dut_pdll_xtal_trim_freq_cal_not_connected |FAIL | XTAL trim could not be performed. Could not detect external input frequency. Current device status = [34].

What can be considered as a cause?

电路：电路应与DA14580DEVKT-B +加速度传感器+外部SPI闪光灯相同
XTAL Trim: enable
GPIO input pulse pin: P0_3 (shared with UART RX)
Externally output pins: VBAT 3, GND, P0_2 (TX), P0_3 (RX), VPP, SW_CLK, SW_DIO

When disabling XTAL Trim, all processing succeeded.
Also, in the case of DA14580DEVKT-P + DA 14580ATDB + Accelerometer + External SPI Flash configuration, it was successful even if XTAL Trim was enabled.

PLTで書き込みを行おうとすると、次のようなエラーが発生します。

dut_pdll_xtal_trim_freq_cal_not_connected |FAIL |XTAL trim could not be performed. Could not detect external input frequency. Current device status=[34].

原因原因として何がが考えますますます

回路: DA14580DEVKT-B と同じはずの回路 + 加速度センサ + External SPI Flash
XTAL Trim: enable
GPIO input pulse pin: P0_3 (UART RX と共用)
外部に出したpin: VBAT3, GND, P0_2(TX), P0_3(RX), VPP, SW_CLK, SW_DIO

XTAL Trim を disable にすると、すべての処理が成功しました。
また、DA14580DEVKT-P + DA14580ATDB + 加速度センサ + External SPI Flash の構成の場合、XTAL Trimをenableにしても成功しました。
