Hello,
I'm trying to get the WAN network port working on the Radxa E20C board.
The latest U-Boot release (v2026.01) doesn't support the port because
the board's DTB file lacks the required "pcie" and "combphy"
definitions. However, the DTB file from the "next" branch already
contains them.
So I applied the following patch to the "next" branch, and I believe I
successfully built U-Boot with support for the port:
--- a/configs/radxa-e20c-rk3528_defconfig
+++ b/configs/radxa-e20c-rk3528_defconfig
@@ -66,3 +66,8 @@ CONFIG_USB_GADGET=y
CONFIG_USB_GADGET_DOWNLOAD=y
CONFIG_USB_FUNCTION_ROCKUSB=y
CONFIG_ERRNO_STR=y
+CONFIG_PCIE_DW_ROCKCHIP=y
+CONFIG_PCI=y
+CONFIG_CMD_PCI=y
+CONFIG_BOOTDELAY=15
+CONFIG_RTL8169=y
To activate the port, I interrupt the boot process and manually run the
"pci enum" command. The output of the subsequent "pci long" command
looks fine (see below).
OpenBSD boots successfully after that, and ifconfig shows two NICs.
However, I cannot get the second NIC to work. The command "ifconfig
re0 up autoconf" appears to succeed, but the NIC never obtains an IPv4
address via DHCP. Instead, the message "re0: watchdog timeout" starts
appearing on the console repeatedly.
My guess is that OpenBSD currently lacks some RK3528/PCIe-related
support. For example, there are no mentions of rockchip,rk3528-pcie in
src/sys/dev/fdt/dwpcie.c. However, I may be completely wrong, so I would
appreciate it if someone could validate this assumption. I'd also be
happy to test any patches if someone is willing to help get this
working.
Below is the full boot log and the commands I ran:
