I've found that verifying a sketch hangs for about 5-10 minutes. This was true yesterday when I was using the 1.2 build and today now that I've been using the 1.3 build. This can't possibly be expected behavior, right? This is to verify the blink sketch--a very, very basic sketch. At first, I just thought the IDE wasn't working, but I just left it for a very long time, and eventually it did successfully compile. However, this is crazy long. Is something misconfigured?
Unfortunately right now the IDE is very slow. We're working on it hoping to increase the speed of verifying and uploading a sketch.
On my Quad (Linaro Ubuntu 12.04 with the included Arduino IDE v0154) it takes 55 seconds to complete a simple program (85 lines, no extra libraries). 45 seconds to complete compile stage + 5 secs upload + 5 secs verify. Slow, but not as bad as OP's!
Is there any update to this. Just got my quad core udoo and everything is good but the time to compile and upload is putting me off.
I'm thinking the CPU is too weak to do actual development with. I get 5 second compiles on my windows deskside computer, no way this SoC is going to ever compare. Its way faster than a pi but if you want to compile sketches you will probably always be waiting the better part of a minute.
