Re: [slim] Installing extra packages on piCorePlayer
Something may have changedits so hard to keep up with testing. But in pCP6.1 the RPI4 used a 64bit kernel with 32 bit userspace. In this configuration, onboard audio did not work with mmap turned on. However USB and i2s cards worked fine. in pCP7, in 64bit system, it does now appear that the headphone jack does work with mmap enabled. piCorePlayer a small player for the Raspberry Pi in RAM.

Re: [slim] Installing extra packages on piCorePlayer
Just been doing a few more experiments. Using piCorePlayer 6.1.0, I finally discovered that the critical step is to change the fourth option on the ALSA output setting to 0. After restarting squeezelite, everything just works, including the GPIO toggling. No reboot required. Once I discovered this, a quick search of the forums found a few threads where Paul had stated that mmap=1 doesn't work on the Pi4B in 64 bit mode. I didn't even realise that 6.1.0 was 64 bit. (Or perhaps it is 32 bit and mmap=1 doesn't work on a Pi4B in any mode?). Can anyone explain what the mmap option actually does? Weird that an audio output setting affects the GPIO control. Anyhow, I then tried out piCorePlayer 7.0.0. Both versions (standard - which I presume is 32 bit, and 64 bit) worked straight out of the box, even with mmap set to 1. Setting the GPIO power on/off worked without any issue. So I guess whatever the issue was with mmap has been resolved in Squeezelite 1.9.8 (piCorePlayer 6.1.0 shows that it uses Squeezelite 1.9.6). But it is interesting to note that the non-working mmap setting seems to affect other apparently unrelated subsystems - perhaps not just the GPIO control. Presumably had Paul or Jeff been aware of this they'd have pointed me in the right direction much sooner. Ironic that if I had waited a few days to start playing around with this and 7.0.0 had been released, none of this would have come to light. But it has at least revealed a possibly useful piece of info for anyone else who encounters the issue.

Re: [slim] Installing extra packages on piCorePlayer
OK, today the GPIO pin suddenly started working as desired, but I had no idea which of the many things I fiddled with had done the trick. So I've spent a lot of time experimenting, being very methodical to try and find out what fixed it. Here's what I found. Bear in mind this is on a RPi4 using piCorePlayer 6.1.0. 1. Flash SD card with a fresh piCorePlayer image and boot up. 2. SSH in and check some things: a). GPIO 13 is in mode IN, voltage low. b). ps -ef shows squeezelite running with these options: *-o hw:CARD=ALSA -a 80 1* 3. Try playing a track: No audio, pause causes track to restart rather than pause, seek skips to position but then plays back a loop of about 5 secs. 4. Set power on/off to GPIO 13, active high. Squeezelite restarts. 5. readall.sh now shows GPIO in mode OUT, voltage high (even though player is off). 6. Switching player on & off makes no difference; GPIO 13 remains high at all times. 7. ps -ef shows squeezelite with options: *-o hw:CARD=ALSA -a 80 1 -G 13 H* 8. Try playing a track: no change, behaviour as in (3) above. 9. Restart squeezelite: no change. 10. Reboot piCorePlayer: no change. 11. Change audio output to RPiDAC and save, then back to analog audio and save. Squeezelite fails to restart. 12. Reboot. 13. Now we have a fully functioning player! a). GPIO 13 behaves as required: voltage low when player is off, high when player is on. b). Playback works correctly: pause pauses, seek skips as it should. c). ps -ef shows squeezelite options: *-o hw:CARD=ALSA -a 80 0 -G 13 H* So it would seem that switching the audio output device is the crucial step that gets everything going. (I speculate that the reason others say "it just works" is perhaps because they had already set their output device to something other than the default analog audio). I am also intruiged by the change in the parameters to the -a option that happened. That second parameter (0 instead of 1) is presumably the thing that got the audio output working. The documentation says that this is the "period count or size in bytes". No idea what that means. In summary, to get it working on the Pi4, the minimum sequence of steps is: 1. Flash SD card with piCorePlayer, boot up. 2. Set power on/off to desired GPIO. 3. Set audio output to something else, save. 4. Set audio output back to analog, save. 5. Reboot. 6. Player now behaves as expected. Mysteries that remain: 1. Why does changing the audio output fix the behaviour of the GPIO control? 2. Why did pause and seek do the wrong things until the audio output was fixed? (It's not like LMS has any idea that the player's output device is set up wrong). Thanks to everyone who helped me with this. It was a bit of an ordeal, but of course orders of magnitude less work than creating my own plugin, as I had originally thought I would need to do!

Re: [slim] Installing extra packages on piCorePlayer
Just done some more experiments and wonder if the results might be at all informative. On the Pi4, I started with both the gpio-poweroff tweak and the squeezelite power on/off option switched off. I never touched the gpio-poweroff tweak during these tests. Logged in via SSH, I checked the state of GPIO 13. It was set as an input, so I set it to output: Code: pcp-gpio mode 13 out Next, I ensured it was low: Code: pcp-gpio write 13 0 and verified that it was low: Code: pcp-gpio read 13 Next, I made sure that the player was switched off in the LMS web interface. Then I turned on the squeezelite power on/off option, setting the GPIO pin as 13 and active high. After saving, which restarted squeezelte, the LMS web interface showed te player as OFF. But when I ran: Code: pcp-gpio read 13 the pin was HIGH, even though the player was off. Switching the player on & off in the LMS web interface made no difference to the state of GPIO 13; it stayed HIGH at all times. So the squeezelite power on/off option is clearly doing SOMETHING with GPIO 13; just not what is expected. Just out of interest, I tried the same experiment but choosing the Active LOW option in the squeezelite power on/off setting. This time GPIO 13 stayed LOW at all times.

Mind you, I did wonder if the fact that LMS is running on version 4.1.0 of piCorePlayer, but the players I'm testing are running version 6.1.0, might be a factor. But that wouldn't explain why the Pi2 started working and the Pi4 still won't. And I still don't understand why the Pi2 started working when it had previously not been. But if you are confident that updating LMS would solve this problem, I'll give it a go. I know it sounds suspicious, but I am 100% certain that I haven't been getting any IP addresses wrong. I just restarted the Pi4, it appears in LMS with an IP address of 192.168.0.107, and when I ssh to that address and play with pcp-gpio, the pins work as expected. But they don't respond to switching the player on & off from LMS. I even went to the extent of re-writing the SD card with a fresh piCorePlayer image and starting again from scratch, just in case something had become corrupted. But it still doesn't work.

Re: [slim] Installing extra packages on piCorePlayer
OK, there are some developments... First of all, when browsing around I discovered this on the Tweaks page: 32642 I wondered if this had anything to do with things, so I tried activating the gpio-poweroff tweak (setting the pin to 13) and rebooted. But it didn't seem to do anything. I deactivated it, rebooted, and then to my surprise the Squeezelite power on/off started working (when switching the player on/off via the LMS web interface). Q: DOES ACTIVATING THE GPIO-POWEROFF TWEAK CAUSE SOMETHING TO GET SWITCHED ON IN THE PI HARDWARE? This was all using the Pi2. So I returned to the Pi4 only to discover that the same sequence of events did NOT cause the power on/off to start working. OK, so now on to Paul's suggestion: paul- wrote: > How many players do you have on your LMS, are you sure you are selecting > the correct player when toggling power? > > There are 2 command line tools provided with pcp. > > pcp-gpio (which will let you do simple things like toggle and output or > read an input.) > readall.sh (This is a simple shell script that reads the current state > of the gpio) > Yes, I am sure it's the correct player. It's the only one called "picoreplayer" in LMS :-) I played around with pcp-gpio & readall.sh, and confirmed that the pins are behaving as they should: readall confirmed that GPIO was in OUT mode "pcp-gpio write 13 1" sets GPIO13 to 3.25V, and "pcp-gpio write 13 0" sets it to 0V. This was verified by both the output from readall, and using my multimeter to check the voltage. But turning the player on & off in the LMS web interface didn't change GPIO13. The voltage shown on the multimeter stayed the same, and the V column in the readall output didn't change. This was on the Pi4. Thinking I might have imagined it working on the Pi2, I returned to that and sure enough the Squeezelite power on/off IS working when the payer is switched in the LMS web interface. (And just to verify things, it also worked when turning the player on & off using the Squeezer app on my phone). So it's all a bit perplexing.

Re: [slim] Installing extra packages on piCorePlayer
How many players do you have on your LMS, are you sure you are selecting the correct player when toggling power? There are 2 command line tools provided with pcp. pcp-gpio (which will let you do simple things like toggle and output or read an input.) readall.sh (This is a simple shell script that reads the current state of the gpio) So start with "sudo readall.sh" and make sure GPIO 13 is an output and the software side is toggling with squeezelite. If this tool shows the output toggling, then you fried your board. If it is not toggleing, then something is setup wrong on the squeezelite/lms side. But use pcp-gpio command to toggle your output.

Should the Squeezelite power on/off setting just work, or do I need to enable it somehow? Incidentally, is there a recommendation for which GPIO pin would be best to use for the power on/off setting?

BCM pin numbering. Which is the numbering almost everything uses. https://pinout.xyz/ Almost nowhere is physical pin numbering used. piCorePlayer a small player for the Raspberry Pi in RAM.

A genuinely embarrassing face-palm moment on my part. That said, I have now tried playing around with the Squeezelite Power on/off GPIO settings, and haven't been able to make it work. Let me just ask a couple of questions to make sure it does what I'm hoping for: 1. The help for the setting says: "Squeezelite will toggle this GPIO when the Power On/Off button is pressed" I interpret this to mean that when I click the power button for the picoreplayer in the LMS web interface (and by extension, if I switch the player on/off using a Duet controller or phone app such as Squeezer), it should toggle the GPIO pin. Is that correct? I hope it is, because that's exactly what I want it to do. 2. What numbering for the GPIO pins is used in this setting? Does it use the physical hardware pin numbers, the (non-sequential) RPi numbering, or some other scheme? I ask this because I've tried both physical and RPi numbering, and neither seem to work. For example, if I set the Squeezelite to use GPIO 13, is this the physical pin #13 (aka GPIO 27 in RPi-speak), or physical pin #33 (aka GPIO 13)? I've tried checking both pins with a multimeter, and neither seem to toggle. Pin #33 (GPIO 13) stays stubbornly high, and pin #13 (GPIO 27) stays stubbornly low. Another way of asking the question: If I set the Squeezelite power on/off to GPIO 13, which physical pin will it control?

Re: [slim] Installing extra packages on piCorePlayer
piCore/Tiny Core uses Extensions, see pCP GUI [Main page] > [Extensions]. This kind of thing has already been done many times. You can access GPIO directly from userspace or use one of the many libraries. wiringPi is depreciated. In /home/tc there are a couple of scripts to look at. squeezelite has the Power On/Off GPIO and Power On/Off Script options. Lots of other stuff that I can't think of just at the moment.

Re: [slim] Installing extra packages on piCorePlayer
You could do all that with a shell script. But assuming you want python. It is available, as well as the python rpio package. Take a look at the extension page from the main menu. If you don't find what you are looking for, ask. We don't package everything, but alot of commonly used stuff is there. piCorePlayer a small player for the Raspberry Pi in RAM.
