Machinekit + Debian Stretch on the BeagleBone Black

[Alexander Rössler]

I just published a write-up on how to create a Machinekit image with
Debian Stretch for the BeagleBone Black:

https://machinekoder.com/machinekit-debian-stretch-beaglebone-black/

I hope you find it useful.

[Daren Schwenke]

Very nice.  I'll be referencing that...  :)

The services to disable for a faster boot is good stuff.

I only had to install dirmngr by itself as installing machinekit seemed to pull the rest in for you, but I started with a different image.

[Lewis Cobb]

Yes Sir !  Something a full-noob like me can understand.  Thanks very much indeed Alexander !

A small noob question here though - can you skip the step of flashing to the EMMC and just set everything up to run on the SD card ? Or will it cause a tear in the fabric of space and time ?

Cheers,
Lewis

[Daren Schwenke]

That will work too.  You now hat three possible locations for globally affecting files then though.

Having the SD card slot available as removable storage is kinda nice though.

[Alexander Rössler]

You can, but flashing to the eMMC is more noob friendly.

Why? Because I noticed some problems with older boot loaders that cause
weird stuff to happen (kernel not loaded, capes not working, ...).

However, if you flash the image first and then use the SD-card image you
should be fine.

RCN has prepared a first BBB testing image with Debian Stretch.

Please give it a try.

[TJoseph Powderly]

Hi, Ive been trying to follow the writeup and fail with
!===> Error: [/dev/mmcblk1] does not exist
at step "Flash the image to BBB eMMC"

I did edited the /boot/uENV.txt file on the cf card to uncomment last line

I booted while holding the SW2 btn untill the user leds began to flicker ( especially User0 and 1 )

In a _very_short time , all leds turned on solid
I inserted the HDMI cable to see if there was any info, and saw the failed flash and error listed above

I've repeated the fail a lot of times now ( 2 days )

I've looked at a lot of info on the web and saw RCN saying
"So either you didn't boot a base image with the eMMC support, or didn't load the eMMC overlay..."
huh? I just ran the instructions on the webpage "https://machinekoder.com/machinekit-debian-stretch-beaglebone-black/"
I didnt see where I skipped anything or needed to choose anything

I tried 3 different cf cards, sha256sum'ed the xz file, and used
 sudo dd bs=10M status=progress if=./bone-debian-9.3-console-armhf-2017-12-10-1gb.img of=/dev/sdb

what to try?

thanks

cat /boot/uEnv.txt

Hello,
I did
'cat /boot/uEnv.txt'
and see the /boot/uEnv.txt on the BBB is NOT commented out.
I logged in via ssh to discover that.

from the web page
"To auto-flash the image when inserting the SD card into your BBB you can uncomment the last line in /boot/uEnv.txt on the rootfs."

It wasn't clear to me that operation was to be done on the running BBB system, rather than the cf card.

I will edit that and reboot now
( I think thats what you wanted me to understand from your reply )

result: same error, mmcblk1 does not exist

so maybe your message
' cat /boot/uEnv.txt'
meant I should post the listing of /boot/uEnv.txt ?

i cant list it at all now
booting is stuck in a loop with failing attempt to write to nonexisting mmcblk1

i need to re-comment that line before i can ssh back in
then post the contents of BBB's /boot/uEnv.txt
so, i have to re dd the cf again
( i dont see how to stop the attempts to flash, ^C ^D etc no effect)

i will copy the file to a thumb drive on attached usb hub, then post it here using the laptop

till later

thanks tomp

[Robert Nelson]

Yeah, that was kinda my point in my last message, if you cat the file
and show us what is has, then we could go from their..

Thanks! /boot/uEnv.txt is perfect... Do you have a usb-serial
adapter, and can you log the serial boot sequence leading up the error
in the flasher?

[TJoseph Powderly]

Hello
yes i have usb to serial ( db9) adapters that i use to talk to old cnc machines with newer laptops
i dont know how to use it with BBB.
I suspect you mean something else,
where can i read about it?
thanks tomp

[Robert Nelson]

Make sure it's a 3.3v one..

Plug it into J1, pinout listed here:

https://elinux.org/Beagleboard:BeagleBone_Black_Serial

fire up tio/screen/gtkterm/etc and just log the serial output from the flasher..

[TJoseph Powderly]

hey i found a prolific pl2303 cable in some raspi stuff
will read up and try to get you the log
thanks tomp

Hello & merry Christmas,

I'm the guy who couldnt flash the BBB due to  'mmcblk1 not found'
You suggested logging the boot till the error
here's the log
sorry its quite long
and
i also booted again (with CF but no btn #2)
then hit SpaceBar to interrupt auto boot
and ran a couple commands in the shell? that may shed some light

the cf card was programmed via
'sudo dd bs=10M status=progress if=./bbb_machinekit_debian-stretch_05_12_2017.img of=/dev/sda'

dont screw up christmas for this!

sorry prev post used MachineKoder's image not yours,
(i have too many cf's here attempting to get the job done, my bad)
i will make clean images from your latest https://rcn-ee.net/rootfs/bb.org/testing/2017-12-24/stretch-machinekit/bone-debian-9.3-machinekit-armhf-2017-12-24-4gb.img.xz
and report back
thanks tomp

ok that (above) image did not goto flash, it went to login despite btn2 held till after 'starting kernel'
actually till after "[    2.072217] hdmi-audio-codec hdmi-audio-codec.0.auto: ASoC: Failed to add route Playback -> direct -> TX"
