Not sure if this is the place to raise this but the latest pythonI2c module appears to have an issue.

I get

python
Python 2.7.13 (default, Sep 18 2017, 20:32:03)
[GCC 5.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
from OmegaExpansion import onionI2C
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: Error relocating /usr/lib/python2.7/OmegaExpansion/onionI2C.so: i2c_writeBufferRaw: symbol not found

The latest i2C packages appear to be broken

pyOmegaExpansion_0.5-1_mipsel_24kc.ipk
pyOnionI2C_0.5-1_mipsel_24kc.ipk

Have the problem I described. I dropped back to

pyOmegaExpansion_0.4-1_mipsel_24kc.ipk
pyOnionI2C_0.4-1_mipsel_24kc.ipk

And the problem went away.

@Paul-Austen said in Latest python I2c module issue:

from OmegaExpansion import onionI2C

Just tried the following minimal workaround

opkg remove pyOnionI2C
opkg install pyOnionI2C_0.4-1_mipsel_24kc.ipk

and this gets rid of the import error

@Paul-Austen my mistake the download URL should be http://repo.onion.io/omega2/packages/onion/

Initially I reset the Omega2 to factory settings using the following from a serial console

firstboot -y
sync
reboot

After setting up the wifi I then copied the following files to flash via scp

pyOmegaExpansion_0.4-1_mipsel_24kc.ipk
pyOnionI2C_0.4-1_mipsel_24kc.ipk

and then ran

opkg install pyOmegaExpansion_0.4-1_mipsel_24kc.ipk
opkg install pyOnionI2C_0.4-1_mipsel_24kc.ipk

This did the trick.

However

opkg remove pyOmegaExpansion
opkg remove pyOnionI2C

Followed by

opkg install pyOmegaExpansion_0.4-1_mipsel_24kc.ipk
opkg install pyOnionI2C_0.4-1_mipsel_24kc.ipk

should do it.

I downloaded the two package files from
http://repo.onion.io/omega2/packages/packages

I believe I know what the problem is. The latest i2C packages are broken

pyOmegaExpansion_0.5-1_mipsel_24kc.ipk
pyOnionI2C_0.5-1_mipsel_24kc.ipk

Have the problem I described. I dropped back to

pyOmegaExpansion_0.4-1_mipsel_24kc.ipk
pyOnionI2C_0.4-1_mipsel_24kc.ipk

And the problem went away.

I have been using the python i2c module and it's been working fine. However even if I start from factory default

E.G
firstboot -y
sync
reboot
wifisetup
opkg update
opkg install python
opkg install pyOnionI2C

I then get

root@Omega-E941:~# python
Python 2.7.13 (default, Sep 18 2017, 20:32:03)
[GCC 5.4.0] on linux2

If anyone has any idea's as to what may be the problem I'd appreciate it

Thanks
