Hi, I have not tried your approach before. I have only done something called netboot. This is where you boot without an SD card at all. There are some hints on how to do it here: https://raspberrytips.com/network-boot-with-raspberry-pi/ Now, I have not actually done it with a Raspberry PI, only with Linux servers and embedded systems, but the principles are the same. You set up a DHCP server, with parameters that tell it where to find the linux kernel and initrd files etc. it then tftp gets them or http gets them. An interesting aspect of this, is that booting over a 1Gbps network is actually quicker than booting from an SD card. Also if the device crashes, as the files are not stored on the crashed device, the files do not become corrupted at all, so it's really helpful when doing kernel development on an embedded system. It not only reboots quicker, but no files are corrupted, and you get to see the last logs before it crashed. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --------------------------------------------------------------
