First of all, many thanks for writing and maintaining the following topic debian-getting-started-with-the-beaglebone-black
I followed the previous tutorial to generate my own minimalist debian image up to the HDMI part where I was a bit confused.
To enable a the hdmi, I need to install a windows manager. However, I would require an access to the terminal on the beaglebone black after booting on the image that I uploaded to an SD Card, right ?
For this purpose, I saw 3 possibilities:
connect through an external USB to serial converter that I would connect to the UART port of the BBB => unfortunately I don’t have one right now
connect through the Mini-USB and use ssh debian@192.168.7.2 => does not seems to work as have a connection timeout message
connect through Ethernet and use ssh debian@192.168.7.2 => leads to the same error for either direct connection to my computer or to the router
After looking at the topic bbb-usb-gadget-questions, it appears that I need to do some manipulation from the beaglebone black to get that enabled.
Well, I was wondering if there is a way to bypass the external USB to serial converter since I don’t have one.
Is there any other way to get a shell access to the beaglebone black ?
Is it possible to install packages directly on the debian image we created on the sd card ?
When I try to boot on the sd card, I have the four led that turn on and a I get a black screen on the monitor. That probably means that the sd card I prepared is not bootable
I will try to boot on an image found there BeagleBoard.org - latest-images first.
Afterwards, I will check what could have gone wrong when I followed: Debian: Getting Started with the BeagleBone Black
4 solid led’s on bootup, mean u-boot tried to do something, but got stuck… Best thing to do is grab a usb-serial adapter and plug it into j1 and see what’s up…
You could also force the microSD to boot via:
Insert microSD
Hold Boot button
insert power
wait for led
lift Boot button
which would indicated an old version of u-boot in the eMMC…
Quick update: I managed to boot on a SD card containing an image from the beaglebone website (using the boot force method you gave)
I did not flash the MMC since I have my beaglebone black which is about 7 years old (2016) so when you mention an old version of u-boot, I think you are totally right.
I don’t have an usb-serial adapter for the moment but I should be able to get one in a few.
After creating a new SD card to boot on (by following instructions on Debian: Getting Started with the BeagleBone Black). I plugged a monitor, a keyboard and a usb to serial converter and it just worked fine. I could access the terminal from the usb -serial converter and/or through the monitor and a keyboard plugged in the usb to the beaglebone black.
The next step is to get a gui.Please let me know if I should open a new topic for that.
Basically I did the following:
sudo apt update
sudo apt upgrade
sudo tasksel
then I followed the instructions to install GNOME
after the installation I performed a reboot and the beaglebone black seems to freeze after some initialization.
Through the usb serial converter I managed to catch the following:
[ OK ] Finished Permit User Sessions.
Starting GNOME Display Manager…
Starting Hold until boot process finishes up…

Then the following message occurs couple of time:
[ 62.241759] davinci-mcasp 48038000.mcasp: stream has more channels (2) than are enabled in mcasp (0)
[ 62.271777] davinci-mcasp 48038000.mcasp: ASoC: error at snd_soc_dai_hw_params on 48038000.mcasp: -22
[ 62.320563] davinci-mcasp.0-i2s-hifi: ASoC: soc_pcm_hw_params() failed (-22)
And finally the Beaglebone seems to freeze and I am unable to do anything from the monitor/keyboard or through the usb/serial converter.
If you want a usable desktop, our Bullesye repo has a meta package for: bbb.io-xfce4-desktop if you just need xorg for a quick application, use openbox…
I shutdown the Beaglebone Black, I removed the sd card and I observed a u-boot error through the usb-serial converter:
U-Boot SPL 2022.04-00037-ge0d31da5 (Feb 22 2023 - 14:02:01 -0800)

spl_register_fat_device: fat register err - -1

SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
I am not too sure what went wrong for u-boot. I tried to flash the emmc twice but ended up with the same result. Could you please help me out with this issue ?
