The R4Pro will come in two versions: the R4Pro-8X and the R4Pro-4E.

The main difference between the two versions is that the 8X features 8GB of DDR and two 10G PHYs that are mounted. The 4E version features 4GB of DDR, without the two 10G PHYs, it uses the MT7988's built-in 1G and 2.5G.

• MediaTek MT7988A Quad-core Arm Corex-A73,1.8GHz processor
• 4GB/8GB DDR4
• 8GB eMMC flash
• 256MB SPI-NAND Flash
• Micro SD card slot
• 1x 10G SFP WAN / 10G phy (Aeonsemi As21011 is the same as Airoha AN8831) - only 8X
• 1x 10G SFP LAN / 10G phy (Aeonsemi As21011 is the same as Airoha AN8831) - only 8X
• 1x 2.5G RJ45 WAN (Option with 1x 10G SFP WAN， support POE with POE Module soldered) - only 4E
• 4x 2.5G RJ45 LAN (MxL86252C)
• 1x 1G RJ45 LAN (SoC builtin mt753x)
• 2x 1G LAN (FPC Connector)
• 2x miniPCIe slots with PCIe3.0 2lane interface for Wi-Fi 7 NIC
• 2x M.2 M-KEY slots with PCIe3.0 1lane interface for NVME SSD (PCIe can switch to M.2 B-KEY slot)
• 3x M.2 B-KEY slots with USB3.2 for 5G Module (2 are sharing pcie-lane with key-m slots)
• 1x USB3.2 slot
• 1x USB2.0 slot
• 1x USB TypeC Debug Console
• 2×13 PIN Header for expanding application

https://github.com/frank-w/u-boot/tree/2025-10-bpi

note:

in my tests sdmmc speed has to be changed to 48MHz else i got mmc errors

arch/arm/dts/mt7988-sd-rfb.dts

&mmc0 {
	pinctrl-names = "default";
	pinctrl-0 = <&mmc1_pins_default>;
-	max-frequency = <52000000>;
+	max-frequency = <48000000>;

this can't reproduced by bpi/mtk so possibly an issue with my sandisk cards…

ubinized image working.

Warnings (NOTICE: UBI: Bad EC magic in block 1008-2031 ffffffff) caused by too small ubi mtd partition on r4pro (has 256 fixed in dts).

https://github.com/frank-w/BPI-Router-Linux/commits/6.17-main

Currently my development state:

V1.0 (6.17-main+):

• SDMMC still only works with reduced speed (48MHz works, 50MHz produces many errors)
• mxl-switch working now
• both usb and pcie working
• mPCIe slots working, m.2 (with switch)
• I2c-mux now detected

V00:

• SDMMC only works with reduced speed
• Trace when mxl port is set to up (if phy not detected before - most times)
• 10G phys not detected and main mdio cannot be scanned
• Eth-Mux not tested because phys were not detected
• Trace for one usb (ssusb0,front=ssusb1 working)
• mPCIe slots working, m.2 (with switch)
• I2c-mux not detected
• SSD-leds behaving weired (off when ssd inserted/recognized, going on system halt)
