Creating SD cards
There is a Windows program that some people use but I only use the Raspberry Pi imager, or sometimes Balena Etcher.
Copy IMG
Mick warns that pi-shrink is unreliable. Here it is all the same.
https://www.instructables.com/How-to-BackUp-and-Shrink-Your-Raspberry-Pi-Image/
I did this on Bellman and worked there I think. I think. Did I make notes?
sudo apt install dcfldd gparted
Building new images
pi-gen is what the Raspberry Pi folk use. See /boot/issue.txt on a standard image. For example,
Raspberry Pi reference 2023-12-11 Generated using pi-gen, https://github.com/RPi-Distro/pi-gen, 2acf7afcba7d11500313a7b93bb55a2aae20b2d6, stage2
Loading an SD card
Thing is, I could use Bellman but that does not help Mick since it's 800 miles away from him. So I am working with pi5 instead since he has access to his own inventory of Pi hardware.
I put the experimental svxlink image into a SanDisk card reader and popped it into a USB slot on pi5. The builtin card reader shows up in /dev/mmcblk0. SD cards are fine but not roomy enough for what I am about, and slow anyway. For pi5, I put the image on an NVME drive so I'd have enough space to work on images. It won't do to build 8GB images on an 8GB card for example. After booting it looks like this.
sudo fdisk -l /dev/sda Disk /dev/sda: 476.94 GiB, 512110190592 bytes, 1000215216 sectors Disk model: RTL9210B-CG Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xdcf0eea7 Device Boot Start End Sectors Size Id Type /dev/sda1 8192 1056767 1048576 512M c W95 FAT32 (LBA) /dev/sda2 1056768 1000215215 999158448 476.4G 83 Linux
The SD card in the card reader shows up in /dev/sda.
sudo fdisk -l /dev/sdb Disk /dev/sdb: 28.82 GiB, 30941380608 bytes, 60432384 sectors Disk model: SDDR-B531 Reader Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x570b8731 Device Boot Start End Sectors Size Id Type /dev/sdb1 8192 532479 524288 256M c W95 FAT32 (LBA) /dev/sdb2 532480 60432383 59899904 28.6G 83 Linux
Now I need tools. I need pi-gen and that needs Docker.
curl -sSL https://get.docker.com | sh sudo usermod -aG docker $USER mkdir Documents cd Documents sudo apt install git git clone https://github.com/RPI-Distro/pi-gen.git
