I did find the output of dmsg a bit odd though. And notice that slot 7 is
still missing after you've successfully loaded the overlay after boot.

I can only guess what is happening. I do not think this could be your fault
necessarily. But perhaps something that needs loading a boot prior to load
these specific overlays. I'm not sure about that, because I've never loaded
that specific overlays . . . just the BB-UART overlays.
anyway, it coul
Because I don´t have this.
ls /lib/firmware/ | grep UART
ADAFRUIT-UART1-00A0.dtbo
ADAFRUIT-UART2-00A0.dtbo
ADAFRUIT-UART4-00A0.dtbo
ADAFRUIT-UART5-00A0.dtbo
But I guess this couldn´t be the problem, right?

You can test this by simply shorting the ground clip to the probe tip and
moving about the board. My guess is the ringing will still be visible.

First, I think the waveforms you are displaying do not look like they originate
from the power rails. I suspect you have a scope probe where the ground wire
and probe tip are too long and you are picking up radiated noise from other
sources. Start by making the scope ground very short. I’m talki
Hi Robert,
I thought I had checked for power supply issues and not found anything, but
I checked again and found problems. Our cape board powers the beaglebone
through the VDD_5V pins on the header.
Here are the VDD_5V (blue) and VDD_3V3B (yellow) rails when the beaglebone
is powered from our
I think the consensus was not not have either installed as default and that way
we keep both side happy. Also, most BBB users don’t use PRU. BTW, I added TJF
to the list since his persistence lead us to this solutions.

This is awesome, but shouldn't one of them be enabled by default? Would be
great to report an issue with rproc not loading as an overlay.

Excellent! UIO has been the only thing keeping me from migrating to Jessie.
I'll report on my findings. I trust this kernel will make its way into a
new stable release on beagleboard.org/latest-images at some point?

Any particular reason why you have to load the adafruit overlays ? What
about these ?
debian@beaglebone:~$ ls /lib/firmware/ | grep UART
BB-UART1-00A0.dtbo
BB-UART2-00A0.dtbo
BB-UART2-RTSCTS-00A0.dtbo
BB-UART3-00A0.dtbo
BB-UART4-00A0.dtbo
BB-UART4-RS485-00A0.dtbo

Here are proper stage 1, and stage 2 uEnv.txt files. From:
debian@beaglebone:~$ cat /etc/dogtag
BeagleBoard.org Debian Image 2016-06-19
*debian@beaglebone:~$ cat /uEnv.txt* */* stage 1*/*
##These are needed to be compliant with Angstrom's 2013.06.20 u-boot.
loadaddr=0x8200
fdtaddr=0x880
Passed that, the only other thing I can think of offhand. Is double check
to make sure you do not have the board file hard coded.
bonegreen == beaglebone green
boneblack == beaglebone black
https://github.com/torvalds/linux/tree/master/arch/arm/boot/dts
lots to choose from though . . .
On Wed,
Try holding and pressing the boot button while booting from sdcard. Let's
see if the new bootloder thinks the old one is too old.

Shall I update the getting-started then? We feel confident enough to
recommend this version?

Okay, starting with r34, (4.4.14-ti-r34/4.4.14-ti-rt-r34)
You can swap between rproc and uio for the pruss...
while, uio can be loaded as an overlay, rproc was failing, so we need
to use the dtb-rebuilder...
Step 1:
upgrade to r34 and reboot:

Hello,
I have a Beaglebone Black:
uname -a:
*Linux c0a800a7 3.8.13-bone63 #1 SMP Mon Aug 11 20:08:34 UTC 2014 armv7l
GNU/Linux*
I want to load UART1, so I added to:
/boot/uEnv.txt:
*cape_enable=capemgr.enable_partno=ADAFRUIT-UART1*
/etc/default/capemgr:
*CAPE=ADAFRUIT-UART1*
but it don´t load:
By adding this argument pair to 'bootargs', the kernel 'found' the
initramfs file..
* initrd=${rdaddr},0x${rdsize}*
where *rdaddr* is 0x8808 and *rdsize* is the size of the initramfs
file. I don't know why it had to be explicitly set where it was not
necessary before.
