IMU

1

• 6-26-09 : location CEB lab
• 6-23-09 : seems to be working
• 1-24-09 : boots and can reprogram - this will be the IMU development device.

• 1-24-09 : removed broken jumper wires from GND to R28. Shorted Q4 gate to ground.
• 1-24-09 : is missing pushbutton switch and is missing PB pad. Remain 3 pads don't seem to be enough to switch the system on.

2

• 6-23-09 : seems to be working with 'blue' cable w/red and black marks on connector
• 1-24-09 : was able to erase and reprogram.
• 1-24-09 : system is getting 3.3V w/push button - however, unable to program over protected segments

todo

• discuss with DY how to recover. Possibly sent back to UPD.

3

• 6-23-09 : seems to be working. appears to have been relabeled with #1 (despite the #3 appearing on two ICs.) removed label
• 1-24-09 : switching regulator gets voltage w/PB, however, 3.3V is unchanged.

todo

• replace switcher U7

IMU cables

• IMU cables with red wire are all subject to intermittent connections due to large wire size. use a small screw driver or xacto to press wires back into IDC slots.
