i.mx6dl的所有的GPIO,在复位期间是低电平,在复位结束后,boot还没有加载,会瞬间变高电平持续约1秒钟后变低电平,这是什么原因,是否有方法不让其输出瞬间的高电平?
Hi yufeng
please check pins state after reset in Table 101. 21 x 21 mm Functional Contact Assignments
and Table 102. Signals with Differing Before Reset and After Reset States
Best regards

根据Table101的说明,i.MX6DL上电复位后出现1s的高电平是正确的,是芯片内部的100K上拉所致,但希望不出现这个瞬间的高电平,cpu是否能实现。
谢谢!
