I have non-sandisk microsd cards that work fine --and other sandisk models of microsd cards that also work. Mostly I use non-ultra sandisk ones as it turns out. But once I could boot via USB I no longer use microsd cards very often in the RPi*'s that can boot from USB without a microsd card involved. > I'm willing to give more information if needed or even to open a = ticket in > bugzilla if you find it useful. It does not seem that my direction of activity is relevant if it is media-type specific for the behavior. So I'll not be experimenting further with any RPi4B's (or otherwise). But if you make a bugzilla report, various things about your RPi* configurations that you have reported would be appropriate to include as context. > Have a great weekend !! >=20 > PS: I've also bought the usb ttl cable if I can give any more = information > using the other card via serial console. There are various settings for getting more debug output on the serial console for the RPi* stages of things. Some go in the config.txt but one goes in the eeprom content. As stands it does not seem that such would have helped for the specific problem: The problem is later, after the RPi* eeprom and firmware stages. You may never need such, but at least you are forwarned about the possibility if you think it might help something in the future. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
