## Troubleshooting: Network does not work on hi35xx
|
|
If network is not working on your hi35xx device after installing OpenIPC (no link), you may have to tune the MII (Media Independent Interface) settings.
|
|
For U-Boot, this is done by setting values for `phyaddru`, `phyaddrd` and `mdio_intf`.
|
|
Possible values for `phyaddru` and `phyaddrd` are: `0-3`, possible values for `mdio_intf` are: `rmii`, `rgmii`, `gmii`.
|
|
For the Linux kernel / OS, values can be set through the `extras` boot variables `hieth.phyaddru`, `hieth.phyaddrd`, `hieth.mdioifu` and `hieth.mdioifd`.
|
|
|
|
Often the correct values can be found in your stock firmware. Viewing the boot logs or running [ipctool](https://github.com/OpenIPC/ipctool) on your stock firmware may provide clues.
|
|
|
|
Below are some combinations you can try:
|
|
|
|
### For ethernet in Linux:
|
|
|
|
In Linux console run this:
|
|
```
|
|
fw_setenv extras 'hieth.phyaddru=0 hieth.phyaddrd=1' && reboot
|
|
```
|
|
If the above settings did not work, try this instead:
|
|
```
|
|
fw_setenv extras 'hieth.phyaddru=1 hieth.phyaddrd=0' && reboot
|
|
```
|
|
Or:
|
|
```
|
|
fw_setenv extras 'hieth.mdioifu=0 hieth.mdioifd=0' && reboot
|
|
```
|
|
Or:
|
|
```
|
|
fw_setenv extras 'hieth.mdioifu=1 hieth.mdioifd=1' && reboot
|
|
```
|
|
Or:
|
|
```
|
|
fw_setenv extras hieth.mdioifu=0 hieth.mdioifd=0 hieth.phyaddru=1 hieth.phyaddrd=2 && reboot
|
|
```
|
|
Or:
|
|
```
|
|
fw_setenv extras hieth.phyaddru=3 hieth.mdioifu=0 && reboot
|
|
```
|
|
|
|
*Note: if a certain combination causes your device to fail to boot, you can clear the variable(s) in the U-Boot prompt by calling `setenv <variable>`, i.e. set the variable using an empty argument, followed by `saveenv`.*
|
|
|
|
### For ethernet in U-boot:
|
|
|
|
Set `phyaddru` and `phyaddrd` variables from U-Boot console:
|
|
```
|
|
setenv phyaddru 0; setenv phyaddrd 1; saveenv; reset
|
|
```
|
|
If the above settings did not work, try this instead
|
|
```
|
|
setenv phyaddru 1; setenv phyaddrd 0; saveenv; reset
|
|
```
|
|
Or:
|
|
```
|
|
setenv phyaddru 0; setenv phyaddrd 0; saveenv; reset
|
|
```
|
|
Or:
|
|
```
|
|
setenv phyaddru 1; setenv phyaddrd 1; saveenv; reset
|
|
```
|
|
|
|
*Note: to initialize and test network connectivity in U-Boot, the `ping` command can be used.*
