ubnt er-x-sfp求助

psyc***

刷了openwrt后，sfp口识别不到…有大佬能解决吗？ 固件原作者手上没有机器，也一起试了很多次，还是不行。

https://openwrt.org/toh/ubiquiti/edgerouter_x_er-x_ka   要单独编译进去这个驱动还要设置好gpio才能在新建接口中看到设备。

1. The routers can supply PoE on the LAN ports. This is controlled by a PCA9555A with GPIO 0..4.
   
2. 
   
3. For documentation purposes - in order to get this running you need, already integrated into OpenWrt:
   
4. 
   
5. install “kmod-i2c-gpio-custom” (pulls gpio and algo-bitbang)
   
6. install “kmod-gpio-pca953x”
   
7. “insmod i2c-gpio-custom bus0=0,3,4”
   
8. “echo pca9555 0x25 >/sys/bus/i2c/devices/i2c-0/new_device”
   
9. export the GPIOs 496..500 (/sys/class/gpio/)
   
10. After reboot you need to run insmod and the echo line below to allow on/off functionality.
    
11. 
    
12. Turn on POE all ports except eth0(WAN)
    
13. #eth0 WAN port
    
14. echo "out" > /sys/class/gpio/gpio496/direction
    
15. echo "0" > /sys/class/gpio/gpio496/value
    
16. #eth1
    
17. echo "out" > /sys/class/gpio/gpio497/direction
    
18. echo "1" > /sys/class/gpio/gpio497/value
    
19. #eth2
    
20. echo "out" > /sys/class/gpio/gpio498/direction
    
21. echo "1" > /sys/class/gpio/gpio498/value
    
22. #eth3
    
23. echo "499" > /sys/class/gpio/export
    
24. echo "out" > /sys/class/gpio/gpio499/direction
    
25. echo "1" > /sys/class/gpio/gpio499/value
    
26. #eth4
    
27. echo "out" > /sys/class/gpio/gpio500/direction
    
28. echo "1" > /sys/class/gpio/gpio500/value
    
29. 
    
30. #turn all POE off
    
31. echo "0" > /sys/class/gpio/gpio496/value
    
32. echo "0" > /sys/class/gpio/gpio497/value
    
33. echo "0" > /sys/class/gpio/gpio498/value
    
34. echo "0" > /sys/class/gpio/gpio499/value
    
35. echo "0" > /sys/class/gpio/gpio500/value
    
36. !!! Update: While using kernel 5.4.33 on an ubnt-erx-sfp I noticed that the gpio numbers had changed as the pca9555 is attributed another gpio base number which is 400. So 496 .. 500 become 400 .. 404.
    
37. 
    
38. Switch Ports (for VLANs)
    
39. ER-X & ER-X SFP:
    
40. 
    
41. Port        Switch port        Label
    
42. WAN        0        eth0
    
43. LAN 1        1        eth1
    
44. LAN 2        2        eth2
    
45. LAN 3        3        eth3
    
46. LAN 4        4        eth4
    
47. N/A        5        eth5 (Only on SFP)
    
48. CPU (eth0)        6

我的私信发不出去了，我刷的是sfp版的固件，链接我现在看看

方便加个QQ吗  我在openwrt论坛上也看到很多人说sfp口用不了，这个问题您有见过吗

刷官方固件，然后按openwrt网上的说明  根据自己的设备gpio情况开启poe和sfp。我没设备测试不了。

你好，我在你发的链接没有看到关于sfp口的说明，可以帮我写个包吗？
