I'll have to take your word for it.
I now have a 5 amp. 5.09 volt supply, hot on gpio pin 2, common on gpio
pin 6, and I just rewrote the debian-10.0.0-armhf-netinst.iso
to /dev/sdf, took it to the rpi4b, and got that same single, 10ms maybe,
flash of the green led. Next I try this .img,
2019-06-20-raspbian-buster.img
And I restarted the ssh daemon on the rpi3, running stretch, so maybe I
can log into it and get something done yet today. gah, damn raspian,
passwds no good.
Change that, reboot after enabling ssh. fixed pw, loggged in.
And I |think| the raspian is booting. After quite some activity of the
green led, its lit solid now, but no damned video. Looks like the new
monitor I bought isn't working, its stuck on the vga input, and the menu
button to change it isn't working, so back to wallies with $80 worth of
junk.
Later.
Cheers, Gene Heskett
