Mallow carrier board and PCIe M.2 (key B)

[marcel.tx]

@Glitch

The new mallow carrier board includes a PCIe M.2 (key B) interface. I understand that this connector type will support a SATA SSD with key B+M

Yes, but only mechanically. None of the Verdin family modules does have SATA functionality.

@Glitch

but I am confused about the PCIe lanes and what this particular board will support.

Nothing to be confused about. As per M.2 spec key B may support any/all of the following:

2 of PCIe ×1, SATA, USB 2.0 and 3.0, audio, UIM, HSIC, SSIC, I2C and SMBus (see M.2 - Wikipedia)

Mallow only supports 1 of PCIe x1, USB 2.0 (and optionally 3.0), UIM and optional SMBus (and further GPIOs).

@Glitch

My question is, will this interface on the Mallow board support an SATA SSD with either a (key B) or (key B+M) interface?

No, it will not.

@Glitch

Is there an example SSD product that has been tested with this board?

Yes, any NVMe aka PCIe capable one with Key B or key B+M. We tested the following:

• Western Digital CL SN520 NVMe SSD
• Toshiba Memory Corporation Model KBG30ZMV128G BG3 NVMe
