It would be super convenient to flash a raspberry pi OS on a microSD card, from the raspberry pi itself (provided that you’re using a different boot microSD card obviously). You don't need to install anything to be able to write and verify images to microSD cards (in a USB adapter). Copy/paste the ...

You can install Raspberry Pi Imager on a Raspberry Pi using:
Code: Select all
sudo apt install pi-imager
I made a bunch or flasher benchmarks on RPi here to compare flash time & speeds.

Oh wow never knew it was that easy! Thank you!

Hello, It would be great if the raspberry pi imager was compiled for ARM (if I can do this myself, please let me know how).

No clue what’s different between the two hdmi groups that will make group 1 work but group 2 cause the issue. HDMI group 1 consists of the CEA (Consumer Electronics Association) modes; these are modes typically used on TVs. HDMI group 2 is DMT (Display Monitor Timings); these modes are typically us...

If the display is falling off the edges then you want overscan enabled (in other words, the opposite of "disable_overscan=1"). For some reason our default framebuffer (the one without the FKMS overlay) seems to disable overscan implicitly (I suspect something to do with u-boot that I haven't had ti...

Hello, Ever since I bought my raspberry pi 4B, i noticed an issue with the screen being too big to fit my tv and ends up being cut off from the edges (this was not an issue with my 3B+). However, on raspbian, adding “dtoverlay=vc4-fkms-v3d” to config.txt did the trick. But, with Ubuntu 20.04 LTS, do...

Hello, Any plans on making a 64bit version of raspbian? I don’t understand why it’s still on 32bits! Staying on 32bits would bring up many issues in the future such as not being able to support more ram and so on. Not to mention that a 64bit OS would outperform the same OS on 32bits. This change is...

Or not use a "beta" release of Ubuntu and wait for the official release. You're bound to have problems. Just use Raspbian Buster lite. I don’t think you’ve read through the thread 😛 I’ve stated that the issue somehow passed on to raspbian buster with desktop... which makes no sense as it’s in a com...

Ah. If wpa_supplicant works then firmware and drivers are ok. Good news. (I suppose you can “flash” Pi4 with any available version of the firmware but I don’t know how to do that, having no Pi4) Something looks incorrect in the boot process then. If it is on Ubuntu 64 I wouldn’t know where the prob...

Pi4 has resident firmware. Does that mean I permanently messed it up? I’m not really sure how to troubleshoot this, let alone how to fix it. Starting wpa_supplicant manually brings wifi right back up, but the moment i close the terminal window that has wpa_supplicant running wifi stops working inst...

Then you messed up the firmware I guess.

How though? These two operating systems are on completely different microSD cards!

You'll have better luck asking the author of that howto I think.

If you’ve read my posts properly then you’ll realize the issue was passed on to raspbian. The author has nothing to do with raspbian.

Ummm, anyone?

I just swapped microSD cards to boot back to raspbian buster and now wifi isn’t working here either. Clicking on the networks panel shows “No wireless interfaces found” and just hovering over it shows “wlan0: Not associated”. raspi-config shows “Could not communicate with wpa_supplicant” when trying...

Hello, I just followed this guide https://jamesachambers.com/raspberry-pi-ubuntu-server-18-04-2-installation-guide/ to install ubuntu server 64bit on my Raspberry pi 4B. I need 64bits as that insanely increases the hash rate when crypto mining. I was able to successfully setup wifi. However, when ru...

Apologies - my search turned up setting this on as admin during the first run on Windows for about four Google pages

Same outcome here haha

From https://wiki.debian.org/Hugepages#Enabling_HugeTlbPage I think the default Raspbian kernel doesn't have it enabled: root@rpi4b:/home/pi# zcat /proc/config.gz | grep HUGEPAGE CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y # CONFIG_TRANSPARENT_HUGEPAGE is not set root@rpi4b:/home/pi# So you'd have to b...

I think you may do better to try on the XMRig support sites (if Google fails) as this is an application question across all platforms not just the Pi. I’ve already given google a try, I only get 2 or 3 search results for the pi (the rest are completely unrelated) and non are of any help as they are...

Hello,

I’m trying to enable huge pages on my rpi 3B+ and 4B for xmrig. They both run raspbian buster. Not sure if it’s possible nor how to do it. Does anyone know?

Thanks!

O.K. I've updated/upgraded Buster on my P4B and "fiddled about" a bit to check the "fall-back to older methods workaround. Two things were necessary for my "overscanning" (desktop off-screen at the edges) T.V. 1) Enable underscan in "Raspberry Pi Configuration", "System" 2) Comment out "dtoverlay=v...

Hello, I just booted up my new raspberry pi 4B with raspbian buster. However, the screen size seems to be too large to fit on my tv.

Hey, Is the raspberry pi 4 still susceptible to getting killed if the gpio pins are shorted? Or has this issue been fixed? (P.s. not sure if this is the correct category to post this) Thanks No, or at least, it will be much MUCH less susceptible. (The problem on the 3B+ is shorting 3.3 to 5v) Alrig...

If the green LED is blinking in a four flash pattern, that is normal. It means the bootcode is present in the eeprom, but no SD card was detected. The Pi 4 is different to earlier models where the initial bootcode.bin had to be on the SD card. Now it is stored on the board. Thank you so so so much!...
