Retroflag Snes case

Sounds like its something to do with pi 3b+ models.

cyperghost · 12 Sept 2018, 20:44

@hurricanefan Do you have annother Pie? It's not the layout of the GPIOs or so... So I think it's rather something with the case.

HurricaneFan · 12 Sept 2018, 20:50

@cyperghost I have a pi 3b thats screwed into another case. I'll try to test that shortly.

@jandalf81 said in Retroflag Snes case:

This way, the fan starts spinning when you set the POWER switch to ON (and doesn't stop while the Pi is powered on).

And Retropie starts only when I set the POWER SWITCH to ON. Correct?

@cyperghost So just finished testing with the same sd card and a pi 3b (not plus) and the safe shutdown and reset code works just fine. The pi 3b+ has something that doesn't like the shutdown/reset code. Super weird!!

@hurricanefan I have the retro flag case and using @cyperghost script and it’s working fine on my pi 3b+

cyperghost · 13 Sept 2018, 07:43

@hurricanefan Please try following, the retroflag scripts enables UART for getting the power LED work
comment out or write enable_uart=0 from your ~~/boot/command.txt~~ /boot/config.txt

HurricaneFan · 13 Sept 2018, 14:36

@cyperghost I don't have a file called command.txt in /boot

I have a file called cmdline.txt is that what you want edited?

cyperghost · 13 Sept 2018, 16:35

@hurricanefan Sorry it's /boot/config.txt

HurricaneFan · 13 Sept 2018, 17:00

@cyperghost changing enable_uart=1 to enable_uart=0 did the trick on my 3b+ pi. Thank you so much!

cyperghost · 13 Sept 2018, 17:40

@hurricanefan Well committed that to my git.

Hi guys, I hope I'm not too off-topic, but I have no idea ho ask about that.

I was wondering if the snes retroflag case switch works as a powerblock.
I mean, one of the most annoying things about the Raspberry is that everytime you plug it, it boots automatically.

With the retroglag snes case (I'm referring to the PAL version) if I plug the raspberry but the switch of the case is set to off, retropie boots anyway or it blocks the booting until I switch it on?

I have the same issue with my rpi2 and a NESPi case + as soon as I plug power into it, it turns on even if the case switch is off, if i then press it on then off it initiates the shutdown command but won't turn back on until I press the switch to on then off again.

Very odd and confusing.

@retroisbest I'm not having issue cause I hadn't buy the case yet. I don't know how to help you

Hi,

I am encountering the same issue as @HurricaneFan with mi 3B+. I installed the safe shutdown script as described in the readme and switched to ON. As this did not work, I found this thread and tried the enable_uart=0 which did not work either. Do you guys have any more ideas?

quicksilver · 17 Jan 2019, 21:06

@wurstsemmesepp did you try cyberghosts copy of the script found here?:

wurstsemmesepp · 18 Jan 2019, 08:03

@quicksilver yes I did, same result, does not work :(

jandalf81 · 18 Jan 2019, 14:21

@wurstsemmesepp I had the same issue, the Power switch just wouldn't work. In my case, the PCB was faulty. I contacted my vendor for a refund, so I got another case. The one I have now works without flaws. You might have the same...

cyperghost · 18 Jan 2019, 16:56

@jandalf81 Or the Pi GPIOs itself are damaged somehow ... but the cases are mass products so it's feasible that there are some rejects.

wurstsemmesepp · 19 Jan 2019, 07:58

Thanks for your replies. Is there an easy way to check GPIO functionality?
The safe shutdown switch seems to work however. When switching from off to on, the LED turns off when the script is not installed and turns slightly darker when the script is installed indicating that its power source changes.

cyperghost · 19 Jan 2019, 11:19

@wurstsemmesepp Yes write a small bash script or use wiringPi and set some GPIOs to low and high. wiringPi offers a list how the state of GPIO is. For function test use a LED and connect it to GPIO and ground. It should light on or light off per current GPIO state.

Here is a small tutorial. You do't need a resistor a breadboard for this ;)
