First off to the developers of 2.0: I love the new IDE. Great job. Can't wait for the bugs to be ironed out.
My problem: I have a large sketch (~2500 lines, TFT, TS, a dozen libraries) that I've uploaded countless times to a SAMD21 board using IDE 1.8x without issues. I've "successfully" uploaded the sketch using IDE 2.0. Unfortunately, most of the code doesn't run following the upload using 2.0. From what I can tell, the TFT screen library & code runs, and perhaps 1 subroutine.
Any ideas? (Sorry, I can't upload the sketch- too big.) The verbose compilation output is really big and I can post that if it would help.
