I just received the Lexar SSD NVME M2 7500MB/s 1TB M.2 2280 PCIe 4.0.
I found out some interesting info about my Nvme journey.
Some basic info for USERs:
-
not all are equal (duh?)
Calm down, what i mean is, some come with a screwdriver kit (two screws) to install it, and some come with nothing. Finding a screw for this is a pain.
-
I have 3 SSDs (now two) , one with 1 GPIO LED, one with 2 GPIO LEDs, and the other without GPIO LED.
-
Power consumption seems to be an issue to boot the board, i will try to explain my findings.
I think this experience (preliminary info) can help others.
I have one board with Nvme 512GB booting from SPI and powered by a 65W PD, earlier i booted from SD Card.
The second one with the Lexar and powered by the 65W PD and the same SD Card (the one that booted with 512GB) canāt boot. The usual boot loop.
Luckily i have here a dumb 5V 4A power adapter that works with the 1TB. I have not tested if it is stable or not. I will find a way to measure consumption with my Kill a Watt (i donāt think it is precise, it is old)
Anyway, to be short, the same setup that works for one does not work for the other.

This is the Nvme for reference:
Edit:
The kernel takes longer to probe this device, thus resetting the PD communication, apparently.
Measured with āKill a Wattā: 6.5 Watt (Peak), 3.4 Watt (iddle)
Edit2:
I tried with a 33W PD charger and guess what, it works.
So, SSD probe timing is irrelevant. I donāt have any means to measure the input Voltage.
