What you cannot see is that under the chip are 297 connections - tiny balls on the bottom of the chip bedded into an array of pads and soldered in place by hot air when the board was made. Impossible to remove the chip without wrecking the board. If any component on the board fails (not sure about the battery or SD card holder), my guess is it's a new board.

That DSP must be expensive, right? Not so. Buy 1000 of them (a months M8 production or so) and AD will sell them to you for around $27 a piece.

Andy, the M8 I took apart was pre-fixed and it looked like the whole recall was down to replacing two chip components by hand on the back of the sensor board.

With a population of M8s out there with the 0.3 chip, any firmware has to run on the oldest chip and so cannot take advantage of fixes to the Blackfin in the meantime.
