Neil Armstrong29f59e82020-09-21 09:34:15 +020021PCIe Setup
22----------
Neil Armstrong29f59e82020-09-21 09:34:15 +020023
Christian Hewitt3cf5e7f2023-03-20 11:45:46 +000024The on-board MCU can mux the PCIe/USB3.0 shared differential lines using a FUSB340TMX USB
253.1 SuperSpeed Data Switch between a USB3.0 Type-A connector and an M.2 Key M slot. The
26PHY driving these differential lines is shared between the USB3.0 controller and the PCIe
27Controller, thus only a single controller can use it.
28
29To setup for PCIe run the following commands from U-Boot then power-cycle the board:
Neil Armstrong29f59e82020-09-21 09:34:15 +020030
31.. code-block:: none
32
33 i2c dev i2c@5000
34 i2c mw 0x18 0x33 1
35
Christian Hewitt3cf5e7f2023-03-20 11:45:46 +000036To revert to USB3.0 run the following commands from U-Boot then power-cycle the board:
Neil Armstrong29f59e82020-09-21 09:34:15 +020037
38.. code-block:: none
39

Christian Hewitt3cf5e7f2023-03-20 11:45:46 +000065Amlogic does not provide sources for the firmware and tools needed to create a bootloader
66image so it is necessary to obtain binaries from sources published by the board vendor:
