Starting today, all the minimal Debian 8 (Jessie) based root file systems options have been replaced by Debian 9 (Stretch).

Which was released over the weekend:
https://www.debian.org/News/2017/20170617
Due to the extra work required for the “barefs” minimization, that’ll take a few days of testing.

hi Robert,
I recently purchased a 4D systems LCD designed for the beaglebone (gen4-4DCAPE-43CT-CLB).
It is connected to a beaglebone green board. As I’m sure you know, the beaglebone green does not have a power jack so the setup is powered through the nimbelink cape.To prevent pin conflicts, the nimbelink cape does not have a module plugged in (its basically just a power source).
The beaglebone green board is running the latest debian stretch =>
debian@beaglebone:~$ cat /proc/version
Linux version 4.9.45-ti-r57 (root@b9-am57xx-beagle-x15-2gb) (gcc version 6.3.0 20170516 (Debian 6.3.0-18)
#1 SMP PREEMPT Fri Aug 25 22:58:38 UTC 2017
When I power on the setup, the LCD backlight comes on and thats about it. I get no cursor, I get no Openbox
I’ve tried disabling the eMMc and boot from SDcard. No success. The backlight did not even come on.
I’ve verified the overlay file on the beaglebone is exactly whats on github.
Any help will be very much appreciated.
thanks toyo
Hi Toyo,
Which Nimbelink cape? We’ve moved to u-boot overlays, please run:
sudo /opt/scripts/tools/version.sh
So we can debug what version of u-boot your dealing with.
Regards,
hi Robert
the nimbelink cape is the beaglebone cape lite
i attached a screen shot of version.sh
thanks
Hi Toyo,
These two capes can’t be used together without modification to the Nimbelink overlay file:
The Nimbelink Cape:
Pins P8_33/P8_35 used for UART4 are needed by the LCD.
Regards,
hi Robert
Thanks so much for pointing this out. I should have looked at the datasheet more closely.
Thought I’d take another crack at the BBB. The Debian Weezy 7.11 works with the 4D Systems 4DCAPE-43T BB-BONE-LCD4-01-00A1.dtbo which is also in the Debian 9 Stretch /lib/firmware directory.
The EEROM of the 4D Systems LCD4.3T display shows up:

I’m guessing it’s something to do with pin 40? This is a stock BBB with no other cards and fresh install of Debian Stretch. Pull the SD card and insert the one with Wheezy and it works. Should not that .dtbo supplied with ‘stretch’ work? Or do new uboot device overlays need to be recompiled and the EEROM changed?
Digikey says they still have 61 of the https://www.digikey.ca/products/en?keywords=1613-1012-ND in stock so there should probably be support for this module?
Which one? There are 5 versions in that link. It’s a 2GB Beaglelbone Black so needs to run off the16GB SD.
Use:
bone-debian-9.3-lxqt-armhf-2018-01-14-4gb.img.xz
It’ll run off the MicroSD, make sure the eMMC doesn’t have a version of U-Boot to get in the way…
Regards,
Took a random stab that bone-debian-9.3-lxqt-armhf-2018-01-14-4gb.img.xz was the one to try.
Don’t know how to make sure “eMMC doesn’t have a version of U-Boot to get in the way…”
Booted with HDMI monitor connected. LXQT came up. Custom Cape for one-wire was discovered but not loaded. Added compiled dtbo but still not loaded on reboot. Will deal with that on a separate subject heading.
shutdown -h now.
Still has 90 second delay till shutdown bug that showed up after Wheezy. Also a separate issue that I will raise on a separate subject heading.
Removed custom cape. installed 4D Systems LCD4 which looks like it was discovered but not loaded.
Blank screen on LCD after boot.
And here’s the output (the 2013 looks suspicious. Is this the uboot getting in the way?):

Yeah your version of U-Boot on the eMMC is too old, it doesn’t know how to handle U-Boot Overlays, thus it’s loading the wrong base dtb and overlays for your Board/cape combination.
Run lsblk, i’m pretty sure in the 2013.04 era we used a fat boot partition, it should be /dev/mmcblk1?
sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100
Regards,
Hi Robert,
You are correct of course.
root@beaglebone:/dev# lsblk

mmcblk1boot0 179:24 0 1M 1 disk
mmcblk1boot1 179:32 0 1M 1 disk
I’m guessing if I clear out the mmcblk1 that I will destroy the Angstrom partition and all my user files.
sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100
Not only that, but since the new distributions no longer come with a FAT partition and the uEnv.txt file needs to be renamed, a working Linux System is mandatory. Up till now with these new distributions I boot Angstrom off the 2GB flash and then insert the MicroSD card and edit the filename to produce the uEnv.txt. Then reboot.
Trashing the /dev/mmcblk1 takes away that ability? Is there not a different solution that won’t kill the Angstrom version on the MicroSD. It’s how I can test that my hardware is still functional.
If I hold down the button above the SD card and apply power I get this with no mention of U-Boot from 2013 but still no LCD display:

Ah still running Angstrom, that image can still be downloaded from beagleboard.org so you can re-install it. (ps Angstrom has been Un-Supported for a few years now…)
Erasing the eMMC, will break Angstrom.
Renaming “/uEnv.txt” as you did will “disable” U-Boot Overlays, this was setup to allow users to use the old Kernel Overlays path (which is also now gone in our v4.15.x kernel branch)…
On the plus side, your cape was detected and U-Boot Overlays:
BeagleBone: cape eeprom: i2c_probe: 0x54: /lib/firmware/BB-BONE-LCD4-01-00A1.dtbo [0xfe93c1f]
So remove /uEnv.txt and erase the version of U-Boot eMMC then retry booting…
Regards,
Alright. Had a few minutes here so I ‘borrowed’ the Milling Machine BBB running machinekit off an SD card.
It had a 3.8.x Debian running off the 4GB eMMC which I don’t use so I trashed the eMMC with dd and renamed the MicroSD card uEnv.txt to bbb-uEnv.txt
And now I have a working 4D Systems LCD4 screen.
However, old as Angstrom and Debian Wheezy may be, they detect both the LCD4 display and the BB-W1-P8.11-00A0.dtbo one-wire prototype cape. So far this version can’t see that proto cape.
In summary:
Have I missed anything?
For the one wire cape, does it have an eeprom, did u-boot detect it?
If not just add this to /boot/uEnv.txt
uboot_overlay_addr4=/lib/firmware/BB-W1-P8.11-00A0.dtbo
However, if that still doesn’t work, i’ll take a look at one-wire tomorrow at work.

Hi Robert,
I’m using the

Once I added
uboot_overlay_addr3=/lib/firmware/BB-W1-P8.11-00A0.dtbo
and rebooted the cape showed up as did the w1_bus_master1 folder.
I chose addr3 because the cape eerom is also wired for that location. Seemed simpler.

I will write up a step by step description of how I got here.
The DS1822+ temperature sensor is on the PC board bottom RHS connected to a proto cape by an eight foot shielded cable. Eventually I’ll have a CAN bus driver too but to do that I have to cut trace on the LCD4 from 4D systems since they used one of the CAN bus signals for the Enter Key.

And you found a bug in my eeprom parser…

and
BeagleBone: cape eeprom: i2c_probe: 0x57: /lib/firmware/BB-W1-P8-00A0.dtbo [0xedc7bef]
I currently exit when i hit “.”…
I need to fix that.
Till then a quick fix is to rename it as “BB-W1-P8-00A0.dtbo”…
Regards,
Robert,
Not enough information for me in your reply.
You wrote.

What “it” is that? Change the EEROM? What needs to be renamed?
Is this bug why
"uboot_overlay_addr3=/lib/firmware/BB-W1-P8.11-00A0.dtbo" is required in /boot/uEnv.txt?
Thanks
John
p.s. Ah. Just looked at your source code. Embedded ‘.’ are not allowed in the file name. So the dts file and resulting dtbo file should be BB-W1-P8_11-00A0.dts (dtbo)
That would explain why I also had a copy of the files named like that. Probably stumbled on that solution by accident. The /lib/firmware has your BB_W1_P9.12 also has the embedded ‘.’.
