你好，NXP：我尝试通过 SPI1 接口进行通信，并且时钟/MOSI 引脚可以输出我需要的数据，但 CS 引脚始终处于高位。您能帮帮我吗？引脚和 SPI 驱动程序之间的设置哪里错误，谢谢。环境描述：MCU：S32K312/100pin S32DS 产品：3.5.0.202207261815RTD S32KXX:RTD5.0.0.202407261948SW32K3_FreeRTOS_11.1.0_5.0.0_CD1_D2409_示例项目附件说明：20250407-SPI1_CS_issue.png 20250407-FreeRTOS_S32K312_SPI_test.7z BR Nelson
我发现我们的电路板存在一个问题，其 CS 引脚上的上拉电阻为 4.7K，我将通知硬件工程部门讨论这个问题。再次感谢Robin_Shen 。
