M.2 connector usage on Mallow

Technical Support

Hi,

I was looking over the datasheets and block diagrams for the AM62 and the AM62P. Am I correct in assuming that the PCIe is still NC for both SOMs? I want to use them in combination with the Mallow board, where I found this post: Mallow carrier board and PCIe M.2 (key B) - Technical Support - Toradex Community.

And if I would connect an M.2 ssd (NVMe) to the connector, would Torizon support the SSD storage natively?

Thanks in Advance!

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

PCIe Support on Mallow Carrier Board

Based on the available sources, I can confirm that the Mallow Carrier Board includes 1x M.2 (Key B) PCIe interface (1). The board specifications clearly indicate PCIe connectivity through the M.2 connector (2).

However, I don’t have specific information in the current sources about:

  • The PCIe status (connected/NC) for Verdin AM62 and AM62P SoMs specifically
  • Native NVMe SSD support in Torizon OS for these modules

To provide you with accurate information about PCIe availability on your specific SoM and Torizon’s native NVMe support, could you help me with a few details:

  1. Which exact version of Torizon OS are you planning to use?
  2. Could you run the tdx-info command on your system to get detailed hardware information? You can find more about this tool at: Getting Device Information with Tdx-Info | Toradex Developer Center

This will help me provide you with precise guidance on PCIe functionality and storage support for your specific setup.

Hello @jippeheijnen,

That’s right, the Verdin AM62 and Verdin AM62P do not have PCIE signals exposed on the SODIMM pins. Therefore you see it is Not Connected in the datasheet.

And if I would connect an M.2 ssd (NVMe) to the connector, would Torizon support the SSD storage natively?

On Torizon OS, you have kernel configs for NVMe already enabled.

# NVME Support

CONFIG_NVME_CORE=m
CONFIG_BLK_DEV_NVME=m
# CONFIG_NVME_MULTIPATH is not set
# CONFIG_NVME_VERBOSE_ERRORS is not set
# CONFIG_NVME_HWMON is not set
# CONFIG_NVME_FC is not set
# CONFIG_NVME_TCP is not set
# CONFIG_NVME_AUTH is not set
# CONFIG_NVME_TARGET is not set

However, you cannot use an NVMe SSD here since PCIe signals are not available. Perhaps you can do it with an adapter to convert USB signals to PCIe signals.
