Beaglebone Black received cannot login/SSH into

Hi,
I ordered BBB from Digi-Key (PART:BBB01-SC-505-ND). I’m using a USB cable to connect to my Windows 10 PC. The BBB boots up; however, I cannot SSH (192.168.7.2) into it. With the debug serial cable enabled, I got te outputs from debug console. Please see attached. I cannot login using either debian/temppwd, root w/o password or root/root. From Windows Network Connections -> Ethernet 2: Remote NDIS compatible device - unplugged
From Device Manager: Network adapters-> Remote NDIS compatible device; Other devices: CDC ECM with an alert symbol ; Ports(COM & LPT) USB Serial Device (COM3), Silicon Labs CP210x USB to UART Bridge (COM4)
I also downloaded latest debian image from https://debian.beagleboard.org/images/bone-eMMC-flasher-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz.
While pressing the boot button and plugin USB to apply the power, the BBB boots from SD card but halts either at:
Gave up waiting for root file system device. Common problems:

  • Boot args (cat /proc/cmdline)
    • Check rootdelay= (did the system wait long enough?)
  • Missing modules (cat /proc/modules; ls /dev)
    ALERT! /dev/mmcblk0p1 does not exist. Dropping to a shell!
    (initramfs)
    (initramfs)

Or freezes at:
mmc0: card never left busy state
[ 3.138875] mmc0: error -110 whilst initialising SD card
[ 33.767499] vmmcsd_fixed: disabling

I had an online chat with Digi-Key tech support, the Technical Reference Number is T4119689. I was suggested to ask for help on this TechForum.
Just wonder if this BBB itself has some issues.

Thanks,

We see this from time to time on the BeagleBoard list. Double check the pin’s inside the microSD connector. They might be bent/broken/etc.

Thanks so much for your quick response. I have spent so much time debugging on this problem.
I cannot easily see the bent or broken pin inside the connector to fix it. Requested a replacement.

Thanks again.
