I'm having the same problems. I have flashed using the full16.bin, double-checked all my solder points, but won't boot when connected. When I remove the chip, everything boots fine.
I also tried putting the EvoX m8_16.bin into an empty bank and making it the boot, but that hasn't worked either.
I've soldered in a lot of chips, but this is my first 1.6 and not sure what I could be doing wrong. The points are good, checked with a multi-meter.
Any ideas?
