Can't erase flash memory in pureThermal ST #9

Please see the terminal-snapshot below. I can't erase pureThermal's flash memory. Please help. What might the problem be?

This is the kind of error you would see if something wasn't plugged in properly, or maybe if the processor didn't have power applied to it.

Hi Kurt,

  1. I still cannot run st-flash erase. I still see the terminal behave exactly as in the screen shot above.
  2. I am following instructions as in the video clip at https://www.youtube.com/watch?v=omKEBaMih5g.
  3. When I connect my ST device to my Mac, I see the power LED glow on the ST, but I measure only 0.611 V on pin J1-VDD of the ARM breakout board (ARMBB), where I expect to see 3V.
  4. When I disconnect the USB cable, I can trace continuity from ARMBB-J1-VDD to my PT1-J9-1, so I know that my FFC is connected properly.
  5. I see no LEDs turn on on the PT1 board because of course there's no 3V going to the PT1.

Please suggest what I might try. Have you seen/heard_of this problem happen to others as well?
