Aaaah I see

ZacckOsiemoOP•12/2/24, 7:49 AM

You are using the Pi as your build box

ZacckOsiemoOP•12/2/24, 7:50 AM

And you compiling for arch that isn’t the same as the pi

ZZacckOsiemo You are using the Pi as your build box

melta101•12/2/24, 7:50 AM

Build box?

ZacckOsiemoOP•12/2/24, 7:50 AM

You are building on your Pi right?

ZZacckOsiemo And you compiling for arch that isn’t the same as the pi

melta101•12/2/24, 7:50 AM

Yes
As of now it's MacOS

Mmelta101 Yes As of now it's MacOS

ZacckOsiemoOP•12/2/24, 7:50 AM

Yes, I understand now

ZacckOsiemoOP•12/2/24, 7:50 AM

Cool stuff

melta101•12/2/24, 7:51 AM

Now
If I combine that with pi gen micro

Hi Guys - any one have any tips for external monitors on the raspberry pi 5? I have a

https://www.amazon.co.uk/dp/B0CJCCDV65?ref=ppx_yo2ov_dt_b_fed_asin_title

attached to the pi through the USB and HDMI - but it just flickers output. I assume the power draw is not enough got it on the usbc - to usba?

Any tips or tricks to get around this?

segfaultdev.elf•12/2/24, 9:53 AM

don't use you usb port for powering something

segfaultdev.elf•12/2/24, 9:53 AM

Just use it in case of data transfer

segfaultdev.elf•12/2/24, 9:54 AM

try with external power supply

segfaultdev.elf•12/2/24, 9:56 AM

specially raspberry pi's they can't provide large amount of current

matthewflynn_•12/2/24, 9:59 AM

Yes I agree - I need to use the usb for touch capabilities though - the unit has 2x usbc outputs though. Can I use one for providing power to it do you think? and one for connecitng to the pi?

melta101•12/2/24, 10:01 AM

do you need a 15 inch monitor?
just curious of the use case

segfaultdev.elf•12/2/24, 10:01 AM

and left one for data + power

Ssegfaultdev.elf so you can use right one for only power

matthewflynn_•12/2/24, 10:04 AM

thanks for that - I'll give this a go.

Mmelta101 do you need a 15 inch monitor? just curious of the use case

matthewflynn_•12/2/24, 10:04 AM

yes and no - its a prototype machine where I need to be able to provide the user with touch screen interface to adjust actuator settings.

matthewflynn_•12/2/24, 10:05 AM

so it does need a touch screen interface for interactivity - not necessarily 15" - it was just in the black friday sale lol

melta101•12/2/24, 10:05 AM

why not a standard 7 inch screen used normally for rpi

melta101•12/2/24, 10:05 AM

you could use hdmi or mipi CSI is even better for that

matthewflynn_•12/2/24, 10:06 AM

damn

it's okay for prototyping but powering a 15 inch monitor won't be much efficient if you think about the facilities it will give

matthewflynn_•12/2/24, 10:11 AM

No i agree - I missed that I could power it through the second usb port. I'll give this a go but I have my finger crossed lol.

segfaultdev.elf•12/2/24, 10:12 AM

okok

matthewflynn_•12/2/24, 10:14 AM

but as an overall solution as long as I provide power through the 2nd port - it shouldn't draw from the pi? Do you think I need to rethink this?

segfaultdev.elf•12/2/24, 10:19 AM

I don’t know actually what will happen then but I think it should have internal protection so that both port can be isolated from each other

matthewflynn_•12/2/24, 12:40 PM

Thanks for all the help guys - I seem to be getting somewhere now (hopefully). I have a usbc cable on power block into display port 2 (for now I just have the usb connection disconnected for testing). when I plug in the HDMI to the monitor the pisture appears for between 5-10 second and then the signal seems to drop? (it remains powered as it flashed red/green/blue cycles). which if I then unplug and replug the hdmi back in the screen appears again.

Now the monitor is mini HDMI so I currently have it connected through a mini HMDI to full HDMI adapter, then micro HDMI to full HDMI?

and

https://www.amazon.co.uk/dp/B08RB28YCZ?ref=ppx_yo2ov_dt_b_fed_asin_title

could this be the issue for the signal drop?

Your Raspberry Pi isn’t detecting the IMX219-160 camera module.
Verify Detection Check with vcgencmd get_cameravcgencmd get_camera. It should show detected=1detected=1.

Try following steps:
1. Install bullseye os on your raspberry pi
2. After booting raspberry pi enter below commands
sudo raspi-config-> interface-> enable libcamera-> save->rebootsudo raspi-config-> interface-> enable libcamera-> save->reboot
sudo nano /boot/config.txtsudo nano /boot/config.txt(enter this command, scroll down till last [all]) under [all] enter the command "dtoverlay=imx708"
Now, save and reboot raspberry pi
Enter libcamera command-
sudo libcamera -hello t 0sudo libcamera -hello t 0
And check if the camera is detecting or not

this results indicate that d rpi doesnt recognise the camera module, check ur configuration
