I upgraded (i think) my Arduino Yun... with the latest image (downloaded .zip, followed instruction to get *sysupgrade.bin visible to luci web.. and did reset to load from image. This all appeared to work.
Your "did it work?" verification seems to consist of "Once the Arduino has reset, your Arduino is a Hybrid Object."
Now... I have nothing responding to :8080...
I see posts to the effect of maybe your router is blocking.. here are the ports... Went thru all of that troubleshooting and finally ended with a proof by adjusting the /etc/uhttpd.conf file adding the line "list listen_http 0.0.0.0:8080"... and viola there are the web backend pages normally seen on port 80! So, no my port 8080 requests are not being blocked.
Ok, so it appears that nothing is starting the server which listens to port 8080.
So i've a number of questions but let's start with 2: (1) There is a HybridObjects folder on the image created with the dd command (fromt he .zip file). Is this copied to the Arduino Yun filesystem? or is this MicroSD card supposed to remain in the slot and (2) what starts up the server? i don't see anything in /etc/rc.d nor in the uhttp server startup that maps anything or causes anything to run. i also don't see anything obvious in output from ps command. (list of processes running that would be responding to 8080.)
I followed all the instructions i can find, read all of the related Forum posts i can find, but without anything responding to :8080 i'm stalled.
