Not all our boards are sensitive alike, but all are plagued by this problem= . Some would require heating the chip, some would require cooling it. We are using Macraigor's Flash Programmer software with a Wiggler or Raven. As anyone also encoutered this type of problem? As anyone an idea what the cause of the problem is, and how to solve it?
