So, I’ll admit to being an Arduino noob, so forgive the confused questions.
However, I’m hoping to use an Arduino Zero + Yun shield, since I want to use the arduino USB host to control a USB-serial device and want to control the controller over Ethernet.
According to the Arduino/Genuino Yun shield documentation, the combination of Zero and Yun shield should work. However, it appears that the only Yun Shield that I can purchase at this time is a clone such as the Dragino shield. I naively expected this to be the same as the official Yun shield.
However, I cannot seem to get the Dragino Yun shield to recognize and/or talk to the Arduino Zero. (In particular, uploading sketches via Ethernet doesn’t work). After the fact, I noticed that the Zero is not listed on the Dragino Wiki and the Zero is not selectable from the Web console as a possible “AVR”.
This leads me to think that perhaps that either (1) the Arduino Yun Shield page on arduino.cc is incorrect, (2) the Dragino shield is fundamentally different from the official Arduino Yun Shield, or (3) I have faulty parts.
Note that I did update everything (I think) including the IDE core, bootloader, and Dragino firmware.
Should my combination work, or is this a fools errand? Is there anywhere to get an official Yun shield? Neither Amazon, Ebay, nor the Arduino store seems to have this part.
