BBB: Flashing Image gets Halted

General Discussion
1

Hi All,

My Beagle Bone Black works fine after flashing, BBB-blank-debian-9.5-iot-armhf-2018-10-07-4gb.

I tried to install a recent image and so, I tried to flash the below image:
am335x-eMMC-flasher-debian-11.7-xfce-armhf-2023-09-02-4gb, and then, when I connect over serial to see what is happening, I get the following messages
"

I have attached the complete log file taken from putty.

My Beagle Bone Black does not get detected over USB as well.

Please share any suggestions on how to proceed further.

Did you write that image directly to the eMMC, or are you using a microSD to ‘flash’ it?

Edit, with that old bootloader … U-Boot 2018.09-00002-g0b54a51eee (Sep 10 2018 - 19:41:39 -0500) hold the ‘s2’ button and toggle reset, should force it to read from microSD.

Hi Robert,

First I prepared a bootable micro SD card and using WINDISK32 I flashed the image into the micro SD Card.

Today, I will try to hold the S2 button and toggle reset and see if the image gets flashed into the EMMC from the micro SD card.

Thank you,
Anu

Hi Robert,

I tired the steps. I think its reading from the MMC but it gets stuck at this point.

Please let me know what needs to be done.

I also have another problem that using serial I am not able to login. But if I use USB then I am able to login.

Thanks & Regards

Hi

On my beagle bone black, I am able to flash EMMC image
“BBB-blank-debian-9.5-iot-armhf-2018-10-07-4gb.img”. This works fine.

I am able to boot from micro SD card using the image
“bone-debian-9.5-iot-armhf-2018-10-07-4gb.img”. This too works fine.

But when I try to boot the board from a micro SD Card with image
am335x-eMMC-flasher-debian-11.7-xfce-armhf-2023-09-02-4gb, I get stuck at:

"Begin: Running /scripts/local-block … done.
done.

And when I try to boot the board from a micro SD Card with image,
am335x-ubuntu-24.04.1-console-armhf-2025-02-26-4gb.img, I get stuck at:

I am not able to understand why some images get stuck at initramfs and some just works fine.

Erase the eMMC, the version of u-boot is too old… It’s messing with newer microSD images.
