Vasanthi,

Would it be possible for you to post some information, i.e. block diagram, part numbers, pictures, of your setup on elinux.org wiki?

I think a lot of people would be interesting in how you got this work!

After upgrading the firmware and changing the power supply to a 5V,3.2A, I was able to see the PCIe SSD.
Thanks all for your help!

I had to go to 0.79 on the main bios from here - http://firmware.intel.com/projects/minnowboard-max

I was at an earlier version and this was the latest at the time.

My power supply is only 5V, 2A. I should up it to 3A or 4A as suggested by some of you.

I do have a separate power supply for the adapter and have ensured it is connected to the mPCIe slot.

@Jeremy, do you remember what version of firmware you updated to? I’m using the core-sato-sdk image from the wiki page and I think that’s at 3.19.

Thanks!

I had this problem before, and one my board.. it seems the high speed connector wasn't working well.  Running a 3 Amp power supply with help, also, on the board you should be able to check for power at a few test points (they where labeled I thought).    Also, I needed a firmware update to help it work too.

Hi all
Is there a way to tell if my silverjaw lure has power going to it when I connect it to the Minnowboard Max? I don't see any led lights turn on.

I have a rather unusual setup with my minnowboard max.  I'm trying to connect a NVMe PCIe SSD to the silverjaw lure by using a "PCIe x1 to mPCIe" adapter on the mPCIe slot.
I'm not able to see this SSD. As a first step, I'm trying to see if there are any power issues.

Thanks!
Vasanthi
