2022年12月17日及以后版本,默认modem 连接采用USB2.0 模式。

如果需要配置成USB3.0 可以通过dd命令把boot 分区修改,重启,已完成修改。

通过openWRT命令行

cd /tmp
dd if=/dev/mmcblk0p3 of=/root/backup-boot-modem-usb20.img bs=1M #备份p3分区
wget https://dl.photonicat.com/images/rk3568-photonicat-openwrt-boot-modem-usb30-202212171614.img.gz #日期需要对应image 日期。如20221217 image,需要boot-modem-usb30-20221217
zcat rk3568-photonicat-openwrt-boot-modem-usb30-202212171614.img.gz | dd of=/dev/mmcblk0p3 bs=1M

重启路由器,搞定。


kernel 6.1.40 2023-07固件 开通USB3.0

cd /mnt/mmcblk0p1
wget http://dl.photonicat.com/misc/rk3568-photonicat-usb30.dtb
cp rockchip.dtb rockchip.dtb.bak
cp rk3568-photonicat-usb30.dtb rockchip.dtb
reboot
