We have been using a micro sd to flash a new image to a debian beagle-bone black board.(pressing the boot button when power is applied with micro sd)

we ordered more boards(same supplier same part number) and tried flashing them with the same method. we have been unable to successfully flash any of the boards. The user LED’s never turn on when we try to flash the board.

any suggestions/tips would be helpful.

Please plug in a usb-serial adapter into the J1 header

And please attach a boot log of a working and non-working board to the
list for us to look at..

can you use usb port(P3)? or is it necessary to use J1 to view boot log?

Anything dealing with 'bootup', J1 is the only way to grab anything
before the kernel loads..

Ok we will need to purchase cable before we can send you boot log

They have changed the chips for eMMC(U13) and SDRAM(U12). could this be causing the problem?

Most likely, and it's probably something we solved a few years ago.

But take a look at your original message, it's lacking lots of
important details, so we can't answer anything, unless you give is
something.

Thus that's why i asked for a boot log..
