The BPi-R4 Pro 4E is a Wi-Fi 7 router board based on the MT7988A SoC.
Difference to 8X is that board has only 4GB RAM and does not contain
the Aeonsemi 10G phys.
Wan port uses MT7988 internal 2.5GBit/s phy with no ethmux chip between
so it need overlays to switch between this wan-phy and SFP-Slot.
Specification
-------------
- SoC: Mediatek MT7988A (4x Cortex-A73 @1.8GHz)
- RAM: 4GB DDR4
- Flash: 256MB SPI-NAND, 8GB eMMC, microSD Slot
- Switch: MT7988A built-in switch, MxL86252C
- Ports: 9 ports, 8 usable simultaneously
* 2x 1G RJ45 LAN
* 4x 2.5G RJ45 LAN
* 1x SFP (LAN)
* 1x 2.5G RJ45/SFP Combo (WAN)
- Buttons: Reset, WPS
- LEDs: Power
- USB: On-board VIA VL822 USB3.2/USB2.0 hub
* 1x USB-A 2.0 connector
* 1x USB-A 3.2 connector
* 3x NGFF-KEYB
- PCIe:
* 2x mini-PCIe slots with PCIe 3.0 2-lane interface
* 2x M.2 M-Key slots with PCIe 3.0 1-lane interface (switchable
PCIe signal with M.2 B-Key)
- Debug: USB Type-C console port
- Power: USB Type-C PD 20V or DC barrel connector
Note: This device comes without a MAC address programmed from the
factory. The randomly generated MAC is stored in the U-Boot env on first
boot and used persistently afterwards.
Installation
------------
Uncompress *sdcard.img.gz and write to microSD card, eg. using 'dd'. Use
bootloader menu on the serial console to install SPI-NAND once installed
to SPI-NAND you can used the bootloader menu to install to eMMC. See
instructions for BananaPi R4 for details.
Description is taken from 8X patch and changed to 4E variant.
R4Pro needed a patch for adding aliases to ensure right probe order so add
this here too.
