Nice to hear that you got it working! As you mention, I remind that 
there was something :-) Some time ago, I was going to use the 
serial port with an LTE shield. I remind I also had to fiddle 
with it to get it working. 

Actually,  RPi 3 B+ has two UARTs. The usual/default UART is 
connected with Bluetooth chip by default, thus the Pins on the 
header are not working - as you already found out.

If you want to use Bluetooth and UART: There is another UART 
in RPi 3 B+ which can be mapped to Bluetooth instead.

you could be using
core_freq=250
dtoverlay=pi3-miniuart-bt
instead of
dtoverlay=pi3-disable-bt

This additional uart does not support full speed / handshake but fast enough
for bluetooth in any case. I think it only works with fixed clock freq.

cheers,
Andreas

Hi,
I got the serial port working. It's a bit of a task. Apparently the
bluetooth integration messed up the serial port configuration so
when you boot, you're actually connected to the bluetooth chip
on /dev/ttyAMA0.  You have to fiddle with /boot/config.txt and
/boot/cmdline.txt to restore the serial functionality.

Additionally, I had to launch a getty on /dev/ttyS0 since
the default starts on /dev/ttyAMA0.

Below is what I changed to get a serial port back on the UART
pins:


root@devuan:~# cat /boot/config.txt
## memory shared with the GPU
gpu_mem=128

## always audio
dtparam=audio=on

## maximum amps on usb ports
max_usb_current=1

## enable hardware-accelerated graphics
dtoverlay=vc4-kms-v3d

## kernel
kernel=kernel8.img

enable_uart=1
# core_freq=250  << not needed anymore when using enable_uart=1

# 2019-07-28 - disable bluetooth
dtoverlay=pi3-disable-bt


root@devuan:~# cat /boot/cmdline.txt
dwc_otg.lpm_enable=0 console=tty1 console=serial0,115200 
root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes 
rootwait



root@devuan:~# tail -2 /etc/inittab
# T0:23:respawn:/sbin/agetty -L ttyAMA0 115200 vt100
T0:23:respawn:/sbin/agetty -L ttyS0 115200 vt100

Hi,
I think it was the power adapter. I have a new 2.5A and got the
Pi to boot. It's weird because I thought I used a 2A adapter to
boot these before. Maybe the adapter is bad.

Do you use a serial port on your PI 3?  I purchased one last week
on Ebay but have no serial output on the UART0_TXD + UART0_RXD pins.

Some searching says to add "core_freq=250" or "enable_uart=1" but
so far still nothing. Any suggestions are appreciated.

Thank you

Hello,
I think you own a RaspberryPi 1st version( or a derivative.. )..

The 'bcm2835' could be found in:
. Raspberry Pi Model A,
. Raspberry Pi Model B, B+
. The Compute Module
. Raspberry Pi Zero

At least the frequency Scheduler reports a fixed value of 700Mhz,
Your BogoMIPS report is also inline with 'bcm2835'( Single core, 32bit 
ARMv11@700Mhz )..

I think you should try with:
https://mirror.leaseweb.com/devuan/devuan_ascii/embedded/devuan_ascii_2.0.0_armel_raspi1.img.xz

If you had already tried,
The best Option, would be to try to fix sdcard frequency to start with a fix

beguining... I am an Early Owner :) )

..try give it 5-5.2V on one of the 5V pins, off e.g. a 4 cell 
"4.8V" NiMh or NiCd battery, charged up to no more than 5.2V.


..beware that both "4.8V" NiMh and NiCd 4 cell batteries can be 
charged up beyond 5.3V, so you wanna discharge your battery to 
5.2V or use a voltage regulator between your battery and your 
RPi4, to protect your RPi4.


..by all means stay below 5.25V (or whatever it is on the RPi4) 
on those 5V pins, or you might burn up your RPi4.

I seem to remember that the raspberry pi 4 needed more than 1A power.

And maybe more than the raspberry pi 3.

Hi,
I don't think the sdcard is a problem as I can mount it on my desktop 
system fine. Sometimes I see weird things like this when there isn't 
enough power (< 1 amp) but I wonder now if my rasberry pi has just gone 
bad.

Does you have any problems with your sdcard?
Shutdown and clean the contacts, then insert it again boot, and wait some time, 
to check if it will resize disk partition to mazx size..
Or if mmc clock is lower, it will take a lot more time to load..

Hi,
I'm trying to boot a Raspberry PI B+ on devuan_ascii_2.0.0_armhf_raspi2.img

I'm getting a boot loop with this output: https://pastebin.com/ALTzdJxW
Any thoughts?

Should I be using the raspi1 image instead?


What is your RaspberryPi version?

In the logs I see:
"
[2.014566] Waiting for root device /dev/mmcblk0p2...

Does you waited enough time?
I don' know that image,
But some do a resize of /dev/mmcblk0p2( and that could take some time.. )
