Does not work with new 3A+ #3
Description
I just attached my new 3A+ with usb male to male cable to Pi3B+ (with no microsd card and no extra power). I see the popup in raspbian, select gpio expander choice. Then it uploads kernel and gpioexpander rootfs however then the progress bar stops before final step and nothing happens.
I suppose the build (kernel, rootfs) is simply old and does not support pi 3A+ yet?
BTW there was another issue that it didn't work at all previously due to conflict with usb host boot, see https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=227044 however this is not the issue. I clearly see my new PI 3A+ is trying to do usb device boot and I see the popup with rootfs choice and broadcom usb boot device in kernel log on pi3B+.
