How to debug unexpected OpenBMC hwmon AST2600 behavior? - debugging

I am debugging a pwmtachtool<->hwmon interaction problem, observed when OpenBMC image is running
on an AST2600 EVB, which is connected to a SensorsBoard and a Fan (Host is not connected).
The running OpenBMC image was built using bitbake, and it includes recipes-phosphor/configuration/entity-manager/SensorBoard.json,
customized for this SensorBoard. Verified that I2C sensors on the SensorsBoard are accessible via i2ctools,
and behave as expected. However, running "pwmtachtool <dev_id> --get-fan-speed <fan_num>" consistently
reports "Fan speed is 0", even though phy Fan is properly connected.
For example:
/usr/local/bin/pwmtachtool 0 --get-fan-speed 0 --verbose
GET_TACH_SPEED:rpm value 0
Fan 0 speed is 0
cat /sys/class/hwmon/hwmon0/fan0_input
0
Looking closely at the pwmtachtool codepath, I am seeing that it calls pwmtach_action(), which reads
"/sys/class/hwmon/hwmon<dev_id>/fan", which is always 0. Tried all <dev_id>/ combinations,
exposed by sysfs: same result. So far, unable to figure out why this is so.
I would really appreciate all recommendations for how to debug this problem.

In my case, the problem was because of J80 jumper connected PWM and TACH lines. So, when I removed it pwmtachtool started to work as expected.

Linux command du returns different size when the same content is, either an image mount to the file system, or under a directory of it

I have a qcow2 image which I have converted to raw format, and then mount to my file system:
# qemu-img convert -O raw initial-image.qcow2 raw-image.img
# kpartx -av raw-image.img
add map loop0p1 (253:1): 0 41940992 linear /dev/loop0 2048
# mount /dev/mapper/loop0p1 ~/myImage
# ls ~/myImage
bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
The size of ~/myImage mountpoint is checked with du command as follows:
# du -hx --max-depth=1 ~/myImage/
0 /root/myImage/dev
0 /root/myImage/proc
0 /root/myImage/run
0 /root/myImage/sys
36M /root/myImage/etc
40K /root/myImage/root
53M /root/myImage/var
12K /root/myImage/tmp
834M /root/myImage/usr
89M /root/myImage/boot
0 /root/myImage/home
0 /root/myImage/media
0 /root/myImage/mnt
0 /root/myImage/opt
0 /root/myImage/srv
1012M /root/myImage/
At this point I copied the contents of ~/myImage and pasted them inside ~/myImage-copy directory. Then I checked the size of the newly created directory. I expected the exact same size for each directory between ~/myImage and ~/myImage-copy, but it's not:
# cp -R myImage/ ~/myImage-copy
# du -hx --max-depth=1 ~/myImage-copy/
0 /root/myImage-copy/dev
0 /root/myImage-copy/proc
0 /root/myImage-copy/run
0 /root/myImage-copy/sys
36M /root/myImage-copy/etc
40K /root/myImage-copy/root
63M /root/myImage-copy/var
12K /root/myImage-copy/tmp
862M /root/myImage-copy/usr
89M /root/myImage-copy/boot
0 /root/myImage-copy/home
0 /root/myImage-copy/media
0 /root/myImage-copy/mnt
0 /root/myImage-copy/opt
0 /root/myImage-copy/srv
1.1G /root/myImage-copy/
From the paths above with different size, I chose /usr and I followed a branch of it until I conclude to an innermost directory which has different size, in order to inspect its files. Below is shown the size difference of an innermost directory:
# du -hx --max-depth=1 ~/myImage/usr/lib64/python2.7/json/
112K /root/myImage/usr/lib64/python2.7/json/
# du -hx --max-depth=1 ~/myImage-copy/usr/lib64/python2.7/json/
164K /root/myImage-copy/usr/lib64/python2.7/json/
However, by inspecting their file content, I can't see any difference related to their size. I don't know if the second column plays a role:
# ls -lah ~/myImage/usr/lib64/python2.7/json/

shopt -s extglob

[root#server atop]# shopt | grep extglob
extglob on
* is matching everything, so *!(8)* is always going to match everything - first !(8) will not match anything (match empty), then * will match everything.
atop_20210 #(3|4) * [0-4] * !(8) *
atop_20210 4 2 8
Why all the *? Remove them. You want to just match what you want to match, not to match anything in between. Just:
atop_20210#(3|4)[0-4]!(8)

(( ten_days_ago = now - 60*60*24*10 )) # subtract 864000 seconds (10 days) from that
date_minus_ten=$(date +%F --date="#$ten_days_ago") # express that number as a YYYY-MM-DD
for filename in lb-quartzcenter.log.* ; do # loop over all matching files
filedate="${filename/lb-quartzcenter.log./}" # remove the filename part before the timestamp
if [[ $filedate < $date_minus_ten ]] ; then # if filename remainder is lexicographically lower...
rm -f "$filename" # ... remove the file
fi
done

How could make nl to enumerate from a specified line.
You just need to use the -v option, and specify to start from 0; your instruction becoming:
ls -lh |nl -v 0
Lets have a look at nl --help:
$ nl --help
Usage: nl [OPTION]... [FILE]...
Write each FILE to standard output, with line numbers added.
With no FILE, or when FILE is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
...
-v, --starting-line-number=NUMBER first line number for each section
Therefore:
$ nl -v0 <<EOF
> a
> b
> EOF
0 a
1 b
Note that it does not really matter whether you want to enumerate directories or anything else, which is why you probably should strip this part from your question to make it more specific.

How to install GCC and/or apt on embedded linux Raspberry Pi

I have a pre-configured linux distro on a raspberry pi (used for a bitcoin miner).
The problem is that this distro is very minimal, only has busybox for basic commands. It doesn't have a package manager and it doesn't even have a gcc compiler. So my target is to install a gcc compiler on it so I can go further and install other software.
So I'm basically limited to these commands from busybox:
root#raspberrypi:~# ls /bin
addgroup fgrep ping6
adduser grep ps
ash gunzip pwd
busybox gzip rm
cat hostname rmdir
chattr ip sed
chgrp kill sh
chmod ln sleep
chown login stty
cp ls su
cpio mkdir sync
date mknod tar
dd mktemp tinylogin
delgroup more touch
deluser mount true
df mountpoint umount
dmesg mountpoint.sysvinit uname
dnsdomainname mv usleep
dumpkmap netstat vi
echo pidof zcat
egrep pidof.sysvinit
false ping

Also tried installing apt-rpm to get apt-get, but it misses a shared libary
root#raspberrypi:~# apt-get
apt-get: error while loading shared libraries: /usr/lib/liblua-5.1.so: internal error
can someone help me on all this??
you've tagged this post as "yocto".
So the only thing I can advice you is using this wonderful tool :)
you don't want to compile your tools from your raspi, but from your killer linux machine :)
first, make sure you have all the prerequisists.
for fedora:
sudo yum install gawk make wget tar bzip2 gzip python unzip perl patch \
diffutils diffstat git cpp gcc gcc-c++ glibc-devel texinfo chrpath \
ccache perl-Data-Dumper perl-Text-ParseWords perl-Thread-Queue socat
for ubuntu / debian:
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat
then, you can get yocto from git://git.yoctoproject.org/poky
git clone git://git.yoctoproject.org/poky -b daisy
then, you need to get the raspberrypi layer and its dependencies:
cd poky
git clone http://git.yoctoproject.org/git/meta-raspberrypi -b daisy
git clone git://git.openembedded.org/meta-openembedded -b daisy
then, setup the build environment:
source oe-init-build-env rpi-build
here rpi-build will be the name of the build directory, it can be whatever you want.
this will setup all the environment variables needed to use yocto, andmove you to the newly create build directory.
edit conf/bblayers.conf
and add the needed layers to BBLAYERS. it should look like something like this:
BBLAYERS ?= " \
/path/to/poky/meta \
/path/to/poky/meta-yocto \
/path/to/poky/meta-yocto-bsp \
/path/to/poky/meta-openembedded/meta-oe \
/path/to/poky/meta-raspberrypi \
"
then, edit conf/local.conf
set the MACHINE variabel to raspberrypi:
MACHINE ?= "raspberrypi"
you can also tell yocto to generate deb files instead of the default rpms by changing:
PACKAGE_CLASSES ?= "package_rpm"
to:
PACKAGE_CLASSES ?= "package_deb"
in order to quickly have dpkg present in the build, just add the following line in your conf/local.conf
CORE_IMAGE_EXTRA_INSTALL="dpkg"
and create a basic image:
bitbake rpi-basic-image
this will take some time.... a LOT of time in fact (yocto will generate the whole rootfilesystem, it will download the sources and compile them, will create deb packages for each of them, and will generate a flashable s image).
during that time I suggest you read the yocto documentation in order to understand how to add more software to the resulting image and / or customise it.
Explaining how yocto works can't just be an answer in stackoverflow you'll need to read the documentation and practice a little bit.
but the main thing to understand is that yocto provides receipes. Basically, a receipe describes how to get a packages and how to compile it.
a simple example of receipe can be found in:
meta/recipes-devtools/rpm/rpmresolve_1.0.bb
the good thing with yocto, is that you can easily add your own receipes.
layers provide supersets of receipes, they also allow customisation.
here, we added the raspberrypi layer in order to add support for the raspberry board.
the raspberry layer provides all the receipes needed to configure the kernel, and the bootloader etc...
once compilation is done, in order to flash the resulting sd image just do:
dd bs=4M if=/path/to/rpi-build/tmp/deploy/images/raspberrypi/rpi-basic-image-raspberrypi.rpi-sdimg of=/dev/sd?
where "sd?" is your (unmounted) sdcard (think about saving it if needed)
plug back your sdcard to your raspi,
boot it.
in order to find out the raspi ip, you can scan your network for open ssh ports:
nmap -p 22 --open -sV YOU_SUBNET_ADDRESS/SUBNET_SIZE
example:
nmap -p 22 --open -sV 192.168.1.0/24
ssh root#RASPI-IP
and voila !
next time you'll need to build a new package, you can do:
bitbake package-name
and then just scp the resulting .deb file (from tmp/work/armv6-vfp-poky-linux-gnueabi/PACKAGE_NAME/PACKAGE_VERSION/deploy-debs/armv6-vfp/PACKAGE.ipk) to the raspi and use dpkg to install it.
you can also create your own image based on rpi-basic-image and adding your own selection of packages.
Exmple with htop:
bitbake htop
scp ./tmp/work/armv6-vfp-poky-linux-gnueabi/htop/1.0.3-r0/deploy-debs/armv6-vfp/htop_1.0.3-r0_armv6-vfp.deb root#myraspi
yocto will be very helpful to ease the cross compilation process for you.
