  • P2000 - SD Card Format

    I can't seem to get our CPU to recognize the formatting of an SD card. I've tried formatting as FAT32 and exFAT on both a Linux and Windows host. Every time I insert the card the CPU displays the message "Portable Memory Dev Unsupport Format".

    SD Card: Lexar 32GD SDHC
    CPU: P2-550 firmware v1.2.2.69

    What am I doing wrong here?

    Tried upgrading to P2-550 firmware v1.2.2.77, no change.

      I am assuming you are using a micro SD and if so which speed? 300X, 633X, or 1000X?

      i have a couple of class 10 micro SD cards they seem to work fine. Only way I can get that message is to try bigger than 32GB micro SD card.

        Not sure about the speed, but the card is a 32GB Micro SDHC. The P2000 manual says it supports cards up to 32GB, but which SD interfaces it supports are not specified (https://cdn.automationdirect.com/sta...2userm/ch2.pdf, pg. 18).

        Would be nice if they'd be more specific about exactly what card and filesystem to use. :P

        Edit:

        Here's the results of f3probe:
        Good news: The device `/dev/mmcblk0' is the real thing

        Device geometry:
        *Usable* size: 29.82 GB (62535680 blocks)
        Announced size: 29.82 GB (62535680 blocks)
        Module: 32.00 GB (2^35 Bytes)
        Approximate cache size: 0.00 Byte (0 blocks), need-reset=no
        Physical block size: 512.00 Byte (2^9 Bytes)

        Probe time: 3'17"
        Operation: total time / count = avg time
        Read: 458.9ms / 4815 = 95us
        Write: 3'15" / 4192321 = 46us
        Reset: 0us / 1 = 0us

          Set the 4 digit password to anything but 0000 for the SD Card.

            Tried a couple of 32GB SD cards now and they all work as expected here

            See notes in help files P196, P270, & P193 as far as teh size and format
            Note: P Series CPUs ONLY support up to a 32GB FAT formatted USB pen drive (P3 Series) or MicroSD (P2 Series).
