Hello,Community
LCD1_DATA [0:23] and 10kΩ pull-down resistor are connected.
Table 96 of the data sheet describes "100K Pull Down" during State during reset.
If i.MX has a pull-down resistor, can I remove the external pull-down resistor?
best regards

Hello,
Although table in i.MX7 Datasheet(s), named "Fuses and associated pins used for boot"
shows default boot pins states - the following is provided in Table 3 (LCD recommendations
for developer's boot modes) of “Hardware Development Guide for i.MX7Dual and 7Solo
Applications Processors”:
"The BOOT_CFG signals are required for proper functionality and operation and should not be left floating".
That is - external resistors should be applied.
