I got a second unit which seems to have very similar issues related to running on battery only. I did the following sequence with the new unit. When I say the Config/Test locks up below, the lockup was seconds after the test started in the portion where the ball moves around the yellow rectangle. This is before the USB portion of the test and the only input to the test from me at this point would be my tipping the unit.
I love the concept of the primer and would really like a realiable unit. I personally was searching for an I/O controller for a project. The primer supports this with its 20 pin IO slot. It also offers debugging, a bidrectional UI. Additionally if offers battery power, audio IO, accelerometer.
Are the problems I am having expected? Is there a solutioins? Any suggestions toward getting me on a path to having a reliable unit would be greatly appreciated.
1. Turn on with battery only.
Result: White Screen, so disconnect batter.
2. Reconnect Battery and turn on. Normal mems ball screen but no audio. (this in the past has meant the that config test that follows will fail).
3. Now do Config/Test and it fails.
4. Now try USB pwr and Battery Together.
Got audio welcoime.
Config/Test worked.
5. USB only:
Config / test lockup. (only USB lockup in this sequence)
6. Usb only: Config / Test runs.
7. USB only works.
9. Usb only lockup.
10 usb only works.
11 usb only works.
12 Batter + USB works.
13 Battery only:
No audio welcome. Config/Test locks up.
14.Battery Only.
No welcome. Config/Test fails.
15 Batt only:
No audio greeting. Config / Test lockup.
