Tool/software:
I have modified the device tree below to support SDR104 mode; Indeed, the TF card can recognize SDR104, but its data line voltage is 3.3V; I have modified the device tree below to support SDR104 mode. How do I modify the file image 78/1000 real-time translation to make the data line voltage 1.8V; Indeed, the TF card can recognize SDR104, but its data line voltage is 3.3V; How can I modify the data line voltage to 1.8V
