Our work doesn't stop during Christmas holidays, and more Linux development updates are coming.
ADC (analog-to-digital converter) was one of features on the 40-pin GP-bus, however, we found this feature brought high complexity in software and hardware developments while we were handling 2 different specifications from Apollo Lake-M ( Celeron and Pentium) and Apollo Lake-I ( ATOM) . We have tried hard to tackle it, but beating against the SoC design is not what we can do in the short term while we need to take the platform's stability into consideration.
After some internal debates and discussion, we have decided to remove ADC from Pentium N4200 and Celeron N3350 SKU and keep ADC in ATOM (x5-E3940) SKU. If ADC feature is critical in your application, you can change the pledge before the end of Kickstarter campaign.
Major differences in SoC
Besides this, there is benchmark in Linux that we've just done by Phoronix Test Suite. We have been testing Ubuntu 16.10 on the UP Squared and it works great! The System was very responsive and could manage multiple multimedia tasks smoothly. In particular on the N4200 we tested Kodi which seemed to work very well also while decoding 4K videos.
Here you go.
Blowfish. (the more the better)
Poisson Pressure Solver ( the more the better)
RSA 4096-bit performance. (the more the better)
Total time. (the less the better)
Global Illumination Render; 100 samples (the less the better)
