How to change the PCIE1_RST output direction?
Mar 04, 2024
I inserted the EC20 LTE Module(it just use USB signals) into the mini-pcie slot.
But I can’t detect device with command “lsusb”.
I found EC20 need pcie_rst(PCIE1_RST) pin always High to enable device.
But PCIE1_RST is always low, and become high level 500ms when boot up.
this is my schemetic, how can I change the PCIE1_RST output direction?
