Hi,

Trying to install the driver on Retropie 4.9.35-v7 / Raspberry Pi 3, i have this error at the 63% step ::

Do you have any advice for this ?

Thanks

while trying to setup my system. and found myself in a restart loop. i discovered that the powerblock and the hifiberry dac+ pro share GPIO pin 18. as soon as i unpluged the dac hat. the restart loop was gone.

i hope this is the right place to put this. im sorry if it isnt

This is reproducible every time in my testing.
Take a clean install of the latest Raspbian Jessie Lite, (in this case on a 64GB card) run:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y cmake g++-4.9
git clone git://github.com/petrockblog/PowerBlock.git
cd PowerBlock
make
sudo make install
sudo make installservice

From here the Pi will either reboot automatically or you do a sudo reboot.
Either way what you end up with is a Pi in an endless reboot loop

I’m trying to change the pins used for status + shutdown as I need one of them for i2s audio output.

I’ve cut the traces for S1 and S2 on the underside of the board next to the header and have changes the config file to use pins 6 and 12, however when I check my log file the powerblockservice reports the pins as 31 and 32 and the pins don’t seem to work. The led just remains slow flashing and toggling the button doesn’t shut down.

I can’t understand why it’s outputting different pin values than configured 🤔

Had this up and running forever, rebuilt a rpi2 and 3 tonight and neither would work (light continuously flashing and switch did nothing. Also noticed that after the install neither pi shutdown.

Noticed changes were made a couple days ago, I ran the uninstall script, rebooted, made the following reversions, re-installed and everything is working fine now.

file /PowerBlock/install.sh

comment line 'updateBootConfig'

file /PowerBlock/scripts/powerblockservice - change as follows

setPinValue() {
  echo $2 > $BASE_GPIO_PATH/gpio$1/value
#-  gpioset $chip $1=$2
}

getPinValue() {
  echo $(cat $BASE_GPIO_PATH/gpio$1/value)
#-  echo $(gpioget $chip $1)
}

I try use PowerBlock with ARMBIAN 5.27.170421 nightly Ubuntu 16.04.2 LTS 4.10.11-sun8i what uses systemd.

Could you consider add native (an unit file) support for systemd too?

Currently powerblock service is handled by

Add a module to the RetroPie-Setup that installs and configured the PowerBlock driver.

While installing PowerBlock (via RetroPie) i've noticed the following message:

make: *** No rule to make target 'uninstallservice'.  Stop.

It seems this is caused by the following:

https://github.com/petrockblog/PowerBlock/blob/release/2.0.0/install.sh#L26

which is probably left-over from the "bash-only implementation" between 1.6.3 and 2.0.0:

release/1.6.3...release/2.0.0
