<p dir="auto">目前hgic_sdspi_init(0)的返回值一直是RET_ERR，主控打印显示是“Reset error. Try reset IO    Illegal command”。</p>
<p dir="auto">逻辑分析仪抓的波形显示，一次运行hgic_sdspi_init(0)中，CS在sd_try_stop、sd_write_byte等位置对应拉低了，MOSI也有波形，但是MISO一直为高。奇怪的是INTIO线上也有波形，会有拉低的波形。我已检查了焊接没有短路等情况，目前SPI的产生的时钟是62kHz。</p>
<p dir="auto">请问这可能是什么问题吗？或者我该如何去排查？</p>
