Firmware updates vis SSD #30
Description
Just another update how we could realise firmware updates in the field:
Have a folder on the SSD, which is called "firmware" and contains as a minimum an "install.sh" file and a file with the firmware version. Plus any firmware files.
On boot, the Raspberry Pi checks if (1) an SSD is plugged in, (2) there is a "firmware" folder on the SSD, and (3) the version number of this firmware is greater than the installed firmware version number.
If yes, it would then run the install.sh script (which would copy all the necessary files and update the version number on the Raspberry Pi) and reboot.
Just an idea. Then customers could upgrade system firmware by simply copying files to an SSD and plugging it in.
