Re: STICKY: PINN - An enhanced version of NOOBS.

If you downloaded the update LineageOS today, you may find the TWRP recovery program still does not work, due to me using the wrong version of sed :oops: . I've now updated it, so the easiest thing would be to reinstall it. (An alternative would be to download the updated partition_setup.sh script a...

Re: Is it possible to record an image on the micro sd using the rpi?

Why not use PINN?
It can install fair number of different OSes on your Micro SD card using the Pi itself (including Arch)

Re: STICKY: PINN - An enhanced version of NOOBS.

The version of LineageOS 16 installed via PINN has been upgraded to Konsta's Feb releases (200207_rpi3 & 200212_rpi4).
The TWRP Recovery mode is now enabled as well when installed via PINN.

Re: unable to get any OS on my new RaspberryPi 4B

Are you using an external USB card reader to flash your SD cards? They are preferred.
Some internal laptop SD card readers are not good at writing the larger SD cards >=32GB

In theory, any SD card available today should work (up to 2TB due to the requirement to use MBR partitioning to boot off). However, as you have a 3B, note this comment from Gordon -> https://github.com/raspberrypi/noobs/issues/540#issuecomment-483652395 I can't remember if this applies to booting ju...

Re: RPi4 with MicroSD Extender Boot Failure

I believe the Pi4B uses a lower voltage mode to get the higher speeds on SD cards. Just a thought, but you could try adding 'sdhci.debug_quirks2=4' to cmdline.txt in the boot partition of Raspbian. (You should see that this option is already added to recovery.cmdline of the NOOBS partition.) As you ...

Re: how to disable everything on boot in Raspberry pi 4

If you are using NOOBS, then you have to do this for both NOOBS and the installed OS. If you are only editing the files on the NOOBS partition, this is not sufficient. You can use the NOOBS 'Edit Config' option to edit the config.txt and cmdline.txt of the installed OS. Additionally, you can disable...

Re: [DEV] LineageOS 16.0 (Android 9) for Raspberry Pi 4 B

@Konsta - Any reason why fstab is called fstab.rpi4 in ramdisk.img, but fstab.rpi3 in ramdisk-recovery.img?
Apart from that, the recovery image seems to have converted ok for PINN. Hopefully there are no other hardcoded partition references in there.

@wodak - you should continue further discussion of PINN in the PINN thread to avoid cluttering Konsta's thread ;)
But the capability you describe is already included in PINN through it's ability to backup an installed OS to a USB device and subsequently reinstall it to another SD card.

It was an ommission of PINN to update the LineageOS recovery image. I am converting the Feb release atm so I hope to fix this at the same time.

It's only used for the analog values that are mapped to the joy_* keys. If the analog value is above the given threshold, it moves the mouse the number of steps to provide some sort of proportional speed control for the mouse. Increasing the first threshold to 1000 will provide some deadband in case...

The speed displayed on download is in megabytes per sec, but it's measuring the number of bytes written to disk after decompressing the files, so the actual network download speed will be less than that. I can't explain your slow download speeds. I only have 39Mbps FTTC, but it's still a lot quicker...

Good work. An easy fix, unlike some of the OSes I come across.
You may want to look at /etc/fstab on sda2 as well and check those references still refer to the correct drives. They may, or may not, need updating.

How are you powering the HDDs? Do they have their own power supplies, or are you powering them from the Raspberry Pi USB ports? The Raspberry Pi is limited in what current it can deliver over USB, so the addition of the 2nd HDD might over power it if they don't have their own supply. In this case, t...

It sounds like you are nearly there. What you are missing is the fixup of the partition references that is normally done by the partition_setup.sh script.
