Re: Busting for Buster? Try it today!

Don't try it on a Raspberry with an AIY hat. I had to rebuild back to Stretch to get that working.

How can I make berryboot images from my 2 sd cards. The 2 sd cards currently work separately.

Don't bother. Just get PINN installed on one SDCard and pick the OS'es you want.

Re: "sudo apt-get upgrade"

Sorry I don't know - if I had any desire to run an insecure ftp server I'd use vsftpd (least bad and I know the developer).

For the FTP stuff I want to do I use sftp which is a built in part of sshd.

Re: WiFi refuses to connect

I went back to 2018-11-13 on the RPi I rebuilt this week (after a failed Buster update). Then applied 177 updates on that.

The WiFi on that one is running rock solid.

Re: USB 2 & 3 compatibility in wifi AP

Ethernet uses the USB2.0 hub on your RPi.
WiFi is entirely separate from USB.

So no, it's nothing to do with that.

Most WiFi problems are to do with the country code setting and mistyped credentials. Nothing more.

Time to build a new SDCard. That one can't be saved. But you will want to collect your programs, data and pictures from it when the new system is built.

Re: Editting fstab

Leave it alone. It will work with PARTUUID (as long as that's the PARTUUID for the boot device). It's also more portable that way.

BTW, can you stop posting photos, images and screenshots. Just cut'n'paste the code into [CODE] tags as that's more useful.

Re: Using a Pi zero with emmc

The Zero isn't a suitable device, too many of the interfaces are missing. You should change the project budget/costs to allow a move to the CM3+ and do the job properly - probably with a custom made CM3+ carrier.

You should switch to a compute module 3+ which has the EMMC on the board and is designed for industrial use.
