Not able to boot via SD Card in my beaglebone black element14

it was due to the eeprom installed on the element14 board, i fixed that…

The fingers in your microSD cage might just be bent? can you read any microSD when booted from eMMC?

Can you suggest how I can check the SD card connectivity to board?
Is the below response gives any indication?

debian@beaglebone:~$ lsblk
NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk1      179:0    0  3.6G  0 disk
└─mmcblk1p1  179:1    0  3.6G  0 part /
mmcblk1boot0 179:8    0    2M  1 disk
mmcblk1boot1 179:16   0    2M  1 disk
mmcblk0      179:24   0 12.5M  0 disk
debian@beaglebone:~$ ^C

That would be your microSD card… IS that the one you’ve previous programmed with etcher.io ? it looks like it has other issues (12.5MB in size)…

Thanks for the response
I have checked once again
Here is the output when this card is connected using Card reader in my ubuntu PC

sda      8:0    0 148.6G  0 disk 
├─sda1   8:1    0   237M  0 part /boot/efi
├─sda2   8:2    0   191M  0 part [SWAP]
└─sda3   8:3    0 148.1G  0 part /
sdb      8:16   1   7.5G  0 disk 
└─sdb1   8:17   1   3.5G  0 part /media/roy/rootfs

Now this card connected to my Beaglebone Black booted from eMMC

ebian@beaglebone:~$ lsblk
NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk1      179:0    0  3.6G  0 disk 
�└�─mmcblk1p1  179:1    0  3.6G  0 part /
mmcblk1boot0 179:8    0    2M  1 disk 
mmcblk1boot1 179:16   0    2M  1 disk 
mmcblk0      179:24   0 12.5M  0 disk 
debian@beaglebone:~$

Here it is 12.5MB only. To make sure, I removed the card and tried the same command. This 12.5MB disappears.

In ubuntu PC, I can see the rootfs filesystem.

btw my eMMC boot details

debian@beaglebone:~$ lsb_release -da
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)

idk… looks like something is wrong with that port on your board…

With 4.19.94-ti-r73, it’s tested, i’d expect it to just work…

Sadly i think your board lost it’s microSD interface…

Thank you very much for the support.
Anyway I think I have a reasonably new Debian in my eMMC. (?) So I will try to learn programing within that and afterwards can do something for the board.
Thanks a lot

I have an update!
Actually the problem was my SD card. It was few years old, (…So the Beagle-bone black also). But both used to work together then. Now I had updated the image in eMMC via Ethernet. Don,t know weather the update caused beagle bone to loose it’s ability to detect low speed old card. Anyway this old card works fine in PC, but not works in my BBB.
To make sure, I purchased a new 32GB card and tried, and now all is OK.
Thanks for the support
