Adding the NVME causes boot loop?

[swulff]

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.

That the computer doesn't have enough power to run?  Maybe that's why it won't boot?

My gut tells me zaius has identified the source of your boot loop problem.

I have a USB 3.0 external hardrive that I can attach and use after the PBP has started. But if I plug it into the PBP then start the PBP, then it goes into a boot loop too. The external hard drive draws too much power when starting to allow the PBP to boot properly (even when the PBP is attached to the external power source), I expect the same occurs with your NVMe drive. It is probably drawing too much power while the PBP is trying to boot.

I reformatted the drive and tried with power adapter plugged in but same issue. So most likely this is drawing too much power.

I do have another laptop with an NVMe in it I could try to swap around but this one is just an absolute pain to crack open.

Im going to scour the forum for a known working one and probably just buy that once the funds have recovered from Christmas time.

Appreciate your input

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;
Wiki - Pinebook Pro - Post NVMe install power limiting

Thanks for your input. I've a question around your guide to set the power states;

If I stick the NMVe into another laptop (given that I can't boot with it in the PBP) and perform this, will it persist in the NVMe or is it something that is OS/Kernel  dependent?
