That is what happens when the wrong kernel is being used. For example
if I use the raspberrypi3 kernel with my raspberrypi2 machine.

I'm sure I put the right kernel in the package though.
and the config.txt will load vmlinuz.rpi3 kernel.


I think that Barry's release did the same (i.e. it didn't work). Maybe they borked something with the 3B+... Raspian installed without a hitch -- but it's not "familiar enough" for my taste.

I'll do some poking around... Smile

Also make sure SD Card is properly prepared.

Windows has special app ---> SD card formatter.
https://www.sdcard.org/downloads/formatter_4/

In linux you should wipe card using following command

You can install using Windows or a Linux computer
Format your micro SD card as fat32 using a windows or linux formatter.
In linux I recommend you zero out the card first...
Quote:
just do "dd if=/dev/zero of=/dev/<flash-drive-device-name> bs=1M count=1". After doing this Gparted will regard you flash drive as completely empty and will offer to create a new MS-DOS partition table - which you should accept.

________________________________________________________


I had previously attempted to install Barry's version on this card, and reformatted it under WinXP -- since it create a second partition, I deleted them both under the XP tool, then reformatted to Fat32. (I thought that his not working might have been a SD error, so I pulled a second -- with same results. Then I reformatted that card, and tried Raspbian -- which installed fine).

I'll have to poke around some more -- it would be fun to get Puppy running on this. The Raspbian system looks too much like it's designed for someone who never wants to see a command line...and much of the time, that's where I live... Wink

I don't have a Pi3+ to test but I am guessing that it needs a newer version of the bootloader firmware and a newer kernel.

I took the bootloader firmware from
http://archive.raspbian.org/raspbian/pool/firmware/r/raspberrypi-firmware-nokernel/raspberrypi-bootloader-nokernel_1.20180328-1~nokernel1_armhf.deb
and compiled a new kernel using kernel-kit from woof-CE because I am not familiar with how Fatdog compiles kernels and I don't think the official kernels include AUFS.

https://www.dropbox.com/s/n9mzhdat91quln3/bootloader-1.20180328_kernel-4.9.80-v7.zip?dl=1

This zip file only includes the new firmware and kernel, you will still need the rest of the files from the fatdogarm-pi3 zip file. I tested this on my Pi3, hopefully I didn't forget to include anything important in the zip file.

Thanks! I'll see if I can tinker a working solution together (and let you know if it works).

I grabbed the Pi3+ because I figured that the slightly faster processor would help me...

I need to redo the uSD card anyway. It appears that I bent the one I was testing (i.e. broke something inside -- I'm going to see if I can scrape the skin off, and patch it... Wink )

I bought a raspberry pi 3 $70 +10 tax CAN

I couldn't get it to recognize the fatdogarm kernel????

However I could use berryboot...

Berryboot has converted Barry's Quirky Arm7 to its format.
I was able to install it on my new raspberry pi3.

Quirky Xerus 8.1.4 for Raspberry Pi 2 & 3 (397.7 MiB, 906 downloads) December 27, 2016
https://sourceforge.net/projects/berryboot-updated-images/files/Raspberry-Pi/quirky_xerus_8.1.4_rpi2_rpi3_2016.12.13_berryboot.img.tar.xz/download

@don570 did you get an original Pi3 or a Pi3+ because the fatdogarm kernel worked for me on my original Pi3 but I don't have a Pi3+ to test.

If you have a Pi3+ would you be willing to test the new bootloader firmware and kernel that I compiled?

The package says pi3. I'll test your bootloader.

Another problem I spotted was the path to the fd-arm.sfs file

basesfs=device:mmcblk0p2:/fatdogarm/fd-arm.sfs

I forgot a colon.

note to woodenshoe-wi

Your bootloader works!!!
It appears that JamesBond 's doesn't.

I have raspberry pi 3 (underneath is printed B+)

The fd-arm.sfs that I put together doesn't work with this model.
I was having sound problems.
I had to use JamesBond's fd-arm.sfs

So it will probably take a couple of weeks to reassemble the fd-arm.sfs again. Rolling Eyes

On the PCB on my Pi3 it reads:
Code:
Raspberry Pi 3 Model B V1.2
(c) Raspberry Pi 2015


If yours says "B+" then I think you have a Pi3+ which would explain why the fatdogarm kernel didn't work for you but did work for me.

I'm glad the kernel works for the Pi3+ because that means new kernels can be made with the woof-CE kernel-kit, and the bootloader firmware came from the Raspbian archive so there should always be up to date versions there.

I won't be able to help you test Pi3+ compatibility because mine is too old Very Happy

Do you have any problems with audio? like stuttering a few seconds on
and a few seconds off.

My raspberry pi2 was working fine with audio.
I want same results with pi3.

Yes and no, I tried an ogg file and it plays fine with xine but not at all with playmuic.

The configuration file for playmusic can set an app to play each format,
such as aplay will play wav and mpg123 will play mp3 format.
perhaps ffmpeg will play ogg??

ffmpeg -i stream.ogg

Boot log says I have Model B+
It looks like the audio chip isn't recognized by the kernel.
Alsa reports that I have BCM2835 chip but that isn't correct Crying or Very sad
That's the SOC that broadcom uses.
That means that I need to compile kernel to recognize chip.

James compiles for arm on an intel computer.

He explains how to do this on his wiki page , but it's hard

I used the kernel-kit from woof-CE on my desktop computer.
Code:
./build.sh pi2-build.conf

But maybe there is something wrong with the config.

There doesn't seem to be any difference between compiling a kernel for a Pi2 and a Pi3 according to https://www.raspberrypi.org/documentation/linux/kernel/building.md but maybe it is out of date?

Do you have "dtparam=audio=on" in your config.txt?

It boots up OK but the audio doesn't play

yes.

I am able to get perfect audio with berryboot's conversion of BarryK


https://sourceforge.net/projects/berryboot-updated-images/files/Raspberry-Pi/quirky_xerus_8.1.4_rpi2_rpi3_2016.12.13_berryboot.img.tar.xz/download

Also the kernel it uses seems better since I can use the safe_mode=1
to get perfect video on my TV set.

This is something I haven't been able to achieve with any other kernel.
