I would be interested in trading some docs for the Oboo clock. I have:
Omega2
Omega Exp doc
Omega 2 I2C shield
Omega IoT interface adapter

Let me know if you are interested.

@Luciano-S. So does Onion still need to release more of their source code to be compliant with GPL? Example, do they need to release the source for their custom wifi driver?

@luz thanks

@wdu @luz

Odd that the Onion guys weren't able to get half duplex mode working.

What is the best way to get a kernel image with the SPI fix? If you could point me to the information on how you created your kernel image I would greatly appreciate it.

I'm new to the Linux world, I apologize for the basic question.

Onion has updated their post indicating a SPI driver fix planned for Q3/Q4 of 2017 to state: "So far, we've tried fully disabling Full-Duplex transmissions, however, this still causes data corruption in Half-Duplex transmissions."

I've had a discussion with Pavel and Lazar concerning the SPI interface. They indicated that they are not spending much time working on it once they discovered the switch to half duplex did not fix the issue.

Their recommendation is to go with the SW bit-bang driver or if higher performance is needed add an external processor to handle the SPI communications or a hardware bridge to the SPI interface such as an i2c to SPI bridge.

Just curious how the open source aspect works...

If Onion is modifying open source drivers, doesn't that make those changes a derived work and therefore subject to the same open source license? And if that is the case, doesn't Onion have an obligation to make the source available if a customer requests it?

I'm doing a build on an omega2, (using the USB for extra storage). When I tried linking my project with the /usr/lib/liboniondebug.so library that was installed using opkg install I got an error that the onionPrint symbol is unresolved.

If I try to list the symbols in /usr/lib/liboniondebug.so the results are:

root@Omega-B82F:/# nm -Ca /usr/lib/liboniondebug.so
nm -Ca /usr/lib/liboniondebug.so
nm: /usr/lib/liboniondebug.so: no symbols
root@Omega-B82F:/# ls -l /usr/lib/liboniondebug.so
-rwxr-xr-x 1 root root 2091 Feb 2 2017 /usr/lib/liboniondebug.so

If I build the liboniondebug.so as part of the git repo for i2c-exp-driver the size is:
root@Omega-B82F:/# ls -l /git/i2c-exp-driver/lib/liboniondebug.so
-rwxr-xr-x 1 root root 7552 Oct 29 01:52 /git/i2c-exp-driver/lib/liboniondebug.so

and if I list the symbols:

I just followed the guide on compileing C & C++ programs on the Omega, the installation of gcc is failing.

I have the omega2 setup to boot from usb, and edited the /etc/opkg/distfeeds.conf.
