Adding the NVME causes boot loop?

Also, I took a look at the webpage for that drive.  It's possible that it's drawing too much power to work properly in the PBP.

Thanks, I will try to format. The power thing may be a factor although it seemed to work fine until I formatted it.. Any idea what a symptom of drawing too much power could be? I don't know much about that side of things but looping in boot seems odd.

Some NVMes allow reducing power. For example, one of mine in my newish desktop has this;

Code:

Supported Power States
St Op     Max   Active     Idle   RL RT WL WT  Ent_Lat  Ex_Lat
0 +     9.00W       -        -    0  0  0  0        0       0
1 +     4.60W       -        -    1  1  1  1        0       0
2 +     3.80W       -        -    2  2  2  2        0       0
3 -   0.0450W       -        -    3  3  3  3     2000    2000
4 -   0.0040W       -        -    4  4  4  4     6000    8000

Then there is a way to limit the drive to a specific power level. Note that power states 3 & 4 are probably some type of standby. So the target of state 2, 3.8 watts is likely the best I can get. (Of course, 3.8 watts is a max, so it may run lower anyway.) Here is a link to limit the power;

My other NVMe drive does not have any changable power states. It runs at 9 watts maximum. Too much in my opinion for our Pinebook Pros.

We still don't have a good idea of what the maximum power draw should be. The Google docs spread sheet for NVMe SSDs has a column for it, but no one has put in any values, yet.

Edit: I figured it was time to add how to change the NVMe power states to the PBP Wiki;
