Hi,

i am using JETSON-IO-BASE-A Rev2 Dev kit, i already loaded the image
“jetson-nano-jp461-sd-card-image” on 64GB SSD card, i insert SSD,keyboard,
mouse,monitor to the kit then i powerup the module,only NVIDIA logo displaying for a long time?

Hi gupta.rajkumar69,

A few things to check, because with the Jetson-IO-BASE-A kits the boot flow is a bit different from the official NVIDIA Nano dev kit.

  1. Confirm what storage you actually flashed
    The file jetson-nano-jp461-sd-card-image.zip is an SD-card image for the official NVIDIA Jetson Nano 4 GB dev kit that boots from a microSD card. NVIDIA Developer Forums

    • If you really wrote that image to a USB or M.2 SSD, it will not boot correctly. The Nano expects that image on a microSD card in the TF/SD slot.

    • Make sure you used a microSD card (32 GB or larger) and flashed it with balenaEtcher or similar, then insert that microSD into the TF card slot of the Jetson-IO-BASE-A.

  2. Check if your kit is eMMC based
    Many Jetson-IO-BASE-A “Dev Kits” from Waveshare use a Jetson Nano module with 16 GB eMMC, and the vendor pre-flashes JetPack 4.6 to the eMMC and enables SDMM3 for the TF card. waveshare.com

    • In that case, the primary boot device is the eMMC, not the SD card.

    • The TF card can be used as extra storage or as an alternative root filesystem, but you normally need to boot the factory eMMC image first, then follow the Waveshare instructions to switch the rootfs to SD or USB. waveshare.com

    So:

    • Try booting once with no SD card inserted. Do you still get stuck at the NVIDIA logo? If yes, your eMMC image may be missing or corrupted and you need to reflash the module.

  3. New DRAM revision can cause “stuck at NVIDIA logo”
    Recent Jetson Nano modules use a newer DRAM (PCN211181). For these modules, NVIDIA provides an overlay package (overlay_32.7.5_PCN211181.tbz2). If this overlay is not applied when you build or flash the system, the board often either shows only 2 GB RAM or hangs at the NVIDIA logo. waveshare.com
    Waveshare explicitly documents that without this overlay “all JetPack versions need to replace some files in order to boot up properly, otherwise they will only stop at the Nvidia logo interface”. waveshare.com

    If you have reflashed the module yourself with SDK Manager or with a custom JetPack, you must:

    • Download the overlay:

      • wget https://developer.nvidia.com/downloads/embedded/L4T/r32_Release_v7.5/overlay_32.7.5_PCN211181.tbz2

    • Extract it in the JetPack directory before flashing:

      • sudo tar -xjf overlay_32.7.5_PCN211181.tbz2

    • Then redo the flash process as shown in the Waveshare wiki. waveshare.com

  4. SD card boot on Jetson-IO-BASE-A is not the same as on NVIDIA dev kit
    On these Waveshare kits, the normal sequence is:

    • Flash and boot a working system on the eMMC first (with overlay applied for PCN211181).

    • Then, if you want to boot from SD or USB, you:

      • Format the TF card or USB device from inside the running Nano.

      • Copy the whole root filesystem from eMMC using cp -ax / /mnt.

      • Edit /boot/extlinux/extlinux.conf to change root=/dev/mmcblk0p1 to root=/dev/mmcblk1p1 (for TF), or to root=/dev/sda for USB, as described in Waveshare’s guide. waveshare.com

    Simply writing NVIDIA’s SD card image to a card and plugging it into a Waveshare eMMC-based kit often does not behave like the official B01 dev kit, because the bootloader and device tree configuration are different.

Please double check the documentation from the vendor.

Hello,

i am using kit having port SD card slot: YES

  • Board color: BLACK

  • Sticker/label: “DDR4 STD 1.2V TE 24502AA”

  • No indication of “2GB” and board is not red

  • Not showing the typical “A02/B01” print because some newer production boards have OEM-style labels

👉 This is almost certainly a Jetson Nano 4GB Developer Kit (B01 variant) — even though the PCB looks dark, some batches look dark-green/black depending on lighting.

then what is the process for write the image?i am following the official website: Get Started With Jetson Nano Developer Kit | NVIDIA Developer
