I have a RAX120v2 being shipped to me, and hoping OpenWrt supports the 5Gbps WAN port.
Have owners of RAX120v2 attempted to use the second (alternative) WAN port (Aquantia AQR111B0 5Gbe Phy) to successfully connect and achieve WAN speeds up to either the 2.5Gbps or 5Gbps settings ?
I found some 2023 information about enabling the 5Gb-multigig WAN port in OpenWrt, but am not sure if this has already been added to v24.10.x ?
Make 5G Aquantia phy work:
For the 5G port labeled 'lan5' to work a firmware is needed. This can be loaded in
u-boot by writing the firmware to the correct mtd partition.
The firmware file found in the Netgear stock firmware under /lib/firmware/ named
'AQR-G3_v4.3.C-AQR_DNI_DR-EQ35AX8-R-prov1_ID23888_VER1311.cld' is needed and has to be converted to a MBN file.
The `mkheader.py` script used here can be found in the Netgear V1.2.8.40 GPL source,
under 'git_home/u-boot.git/tools/mkheader.py'
Convert the CLD file to MBN using:
$ python2 mkheader.py 0x44000000 0x13 <*.cld file> aqr_4.3.C.mbn
This MBN file can then be flashed to the MTD partition to be used by u-boot.
The necessary files can also be found in
https://github.com/boretom/openwrt-fork/tree/rax120v2/aquantia-firmware
* Write MBN file to MTD partition to be loaded automatically by u-boot:
U-boot automatically tries to load the firmware from nand at address 0x7e00000 which
corresponds to `/dev/mtd25` in OpenWrt.
- find ETHPHYFW partition while running OpenWrt (expected: /dev/mtd25)
$ fgrep -i 'ethphyfw' /proc/mtd
mtd25: 00080000 00020000 "ethphyfw
- copy mbn file to /tmp/ folder of the router
$ scp aqr-v4.3.C.mbn 192.168.1.1:/tmp/
- write mbn file to ethphyfw partition
$ mtd write /tmp/aqr_v4.3.C.mbn /dev/mtd25
Revert to stock firmware:
* Flash the stock firmware to the bootloader using TFTP/NMRP.
