Hi all! I'm new to all this, and can use all the help I can get! Argon M.2 & RasPi4 was delivered today, and the WD Blue SSD would get delivered tomorrow.
Reading the above comments, I gather I can directly flash my SSD with Astroberry while it sits in the M.2 via usb cable to laptop. It is also recommended above that I fully upgrade the firmware of the RasPi before trying this.
My question is, can I upgrade the firmware without the SD Card? I'd like to have everything on the SSD.
