How to Allocate RAM to the GPU on the Raspberry Pi 5? (SOLVED)
The title basically sums up my question, but I’m just wondering how to do it. As far as I can tell there is no obvious way to do it. With past Raspberry Pi’s you could either edit the config.txt file and change gpu_mem or go to the Raspi-Config screen and fichan free it there. There doesn’t seem to be either of those options on Raspberry Pi OS Bookworm. Is this because of the OS, which can’t be changed to previous OS’s, or is it because of the Raspberry Pi 5? This is just super confusing!

pico w/ Lipo shim power issues - no power at vbus pin
Hi all. I’ve added a lipo shin to my pico but I’m having power problems with it, basically it won’t power the pico as it should, details are below:
The power out of the lipo connector is good (at source)
Voltage at the 3v3en pin is good, this goes on and off with the button on the front of the shim.
If I bridge power from the +ive on the back of the plug to the VBUS pin we get power and everything works as it should.
However if I bridge from the 3v3en pin (same voltage) then the pico still won’t power on
If I don’t bridge anything then there’s still power to the 3v3en pin but nothing to the vbus pin
I’ve checked all soldered joints and I can’t see any issues. Does anyone have any ideas which pins I should check in particular or anything further I could do to trouble shoot?

Can someone help me with my noctua fan?
I have a noctua fan, the NF A4x10 5V fan, I currently have it on the 3 to 2 pin adapter, so the yellow wire labeled "RPM Speed signal" in the docs is unused, Does anyone know what pin i should put that into so I can use it? I have red wire in 5v and black in ground but yellow unused, and I would like to be able to use it.

my raspberry pi5 is not compatible to the touch screen I bought.
I got a CX070PI-A IPS 7-inch screen and a Rpi 5. The screen itself works but not the touch screen. However, when I connect the touch screen port from my screen to my normal pc, then it does work so its not the screen but the software of the Rpi. I checked Github and saw a few issues in the past with update 5622, that I installed but no change. I switched back from wayland to X11 but that also did not work and I disabled the entire KMS drivers that also didnt work. ANy tips?

Voltage Divider
Hey Folks,
trying to copy parts of the kinowheels.com project and attach it to a pico instead of an Arduino mega.
So far i replicated just one of the voltage divider and attached only one of the outs of the encoder to my breadboard. Yet I did not added the pico as i measured ~5V (encoder HIGH) on the tap where it should be connected.
Is this due to not having a load (no pico, just volt meter) attached?
When i add another 20kOhms between tap & ground i get desirable 2.5V, but i don't know if i'm doing it right.
Appreciate any help!

Need help booting from USB
Hi,
I recently bought a Pi4 to use as server for Home Assistant. I also bought a USB to SATA-connector to use a old(ish) SSD as boot device. However, I am having issues booting from the USB.
From Googling I found that most people said you needed the official power adapter, which I bought and just got. Besides this, I've flashed a SD-card to get USB boot into the Pi. It works perfectly - the green light flashes rapidly. After this, I disconnect the power to the Pi, I insert the USB with the SSD, and give the Pi power. The red light is constantly on, with the green light flashing fast once, followed by keeping the light on for about 10 seconds. After that the green light turns off, and repeats after about 10 seconds.
Any help is appriciated!

RaspAP not finding clients anymore after raspbian reinstallation but working in terminal.
Hi.
As mentioned in the title it did work but I messed up my raspbian installation and had to redo it. Now it won't find any clients I could associate with anymore.
It doesn't show up clients I can connect with my secondary usb plugged in alfa adapter "wlan1" on the web config page. Scanning in terminal is working fine
If I scan for wifis in terminal my wlan1 is working and showing it correctly.
What am I missing?
Cheers! Max

Weird display (framebuffer?) issue.
I've got a 480x800 display in HDMI-1, and a 1920x1080 in HDMI-2. I normally keep HDMI-1 in an orientation where I have to set its rotation to "left" and it then becomes 800x480. But whether or not I rotate it, HDMI-2 shows the contents of HDMI-1 on the right side of the screen, but with the top line of pixels missing. I've tried numerous adjustments in arandr and in /boot/config.txt to no avail. Also of note is that anything I click on on the right screen, the actual click happens about 2 inches to the left of wherever the arrow is. If I move the arrow onto HDMI-1, it doesn't show up in the area of HDMI-2 where HDMI-1's screen is showing, but the effects of me clicking do.
But where it gets really weird is that if I set the rotation of HDMI-2 to inverted, it works perfectly fine, other than it's annoying having my monitor upside down.

SERVO2040 (New User)
Hello,
I’ve never used a raspberry pi before and I have a SERVO2040 and I’m not sure if it’s working right. What happens is the onboard leds are rgb but only flash red. Also I’m using Mu Editor and circuit python. I have no idea what I’m doing but I’m just following the circuit python welcome guide. Also the leds turn like whitish when I press serial and any key in Mu Editor.

Help with Electronic Ink Screen
Hello
I need help setting up my e-ink raspberry pi screen.
I recently bought a Raspberry Pi 4 model b and a programmable e-ink screen.
I've been searching on the internet for tutorials on my topic, but all i can find are animation demos for the screen. I am wondering if it would be possible to use it as the main display, just like using a monitor with the micro-HDMI. My monitor is the Waveshare 4.2 inch e-paper module. Thanks

Problems when running python code on raspberry pi 4b
I've been trying to connect a raspberry pi 4b to ads1115 for a few days now. I've never worked with this board before and I'm totally new to this. The wiring is correct from what I have seen on the internet, but when I download the library from the Adafruit ADS1X15 I get an error when running the code. I work with Python and operating system is Raspberry OS Lite. I have tested the board with Arduino and C++, it works without any problems. This is part of my thesis project and I would appreciate your help.

Sixfab 4G/LTE Cellular Modem Kit or USB Cell in / USB wifi out RPI5
Hello, and if you are reading this thanks for taking the time to help. I was curious, before I buy a Sixfab 4G/LTE Cellular Modem Kit (Telit LE910C4-NF) for my kit I was wondering if a 3G/4G LTE USB antenna modem with sim or 4G/5G Dual Band USB antenna modem with sim would work just fine across country as my data input source, while also on the same Pi 5 8gb board using a USB Dongle of some type to output Wifi 5 (and 6/6e if possible) to output the mentioned wifi? Also, when I program the Pi to function in this manner, could I also program (or would I even need to program?) the Pi 5 to also allow output via the ethernet port, or would I need a micro usb to Ethernet Port device? Thanks in advice for any help. This is my first project with the Pi and I want to have the right hardware before messing around with trying to program this, as well as using OpenWRT as I think i must. If the dongles will provide a similar result as the Sixfab option it is much cheaper. Any suggestions on the model of each usb device you would use? Thank you again in advance!
