Raspberry Pi Imager + rpiboot takes 40 mins to flash 8GB memory

See original GitHub issue

Using:

Raspberry Pi Imager v1.7.1 and
RPIBOOT: build-date Jan 26 2022 version 20220111~130126

And it takes 40 mins to flash a 8GB CM4 eMMC device (with rpiboot jumper set).

Flashing 12 units takes me a whole day. Is there anyway to speed it up?

N.B. Raspberry Pi Imager (embedded - https://github.com/raspberrypi/rpi-imager ) can also be loaded via RPIBOOT. This is also quite fast because the network download happens on the CM4. However, it doesn’t export the disks via MSD so it depends on what you what to do.

The boot.img can be downloaded from here https://downloads.raspberrypi.org/net_install/

At some point I’ll write a shell script to usbboot to downloaded the latest boot.img and launch rpiboot to add the embedded imager as an official “rpiboot program”

@mangelozzi The first release of the Linux initrd imager that I mentioned is now available. For me it flashed the normal Raspberry Pi OS in about 5 mins Instructions here https://github.com/raspberrypi/usbboot/issues/119#issuecomment-1064093364

cmprovision will give the best performance because it’s downloading the data over 1Gbit Ethernet, however, it’s a bit more complicated to setup.
