Re: dtb control

I have the "right" dtb for the hardware (t9, really H96max+), armbian boots OK, few or none error mesgs in dmesg If the dl was bad, the xz would be corrupted, fail to extract.

Re: Running out of disk space and don't know why

ncdu makes it easy (new curses) ,, starts in the directory you invoke it,
with the current users rights, su (or sudo) for full power,, carefull !!!
It does take a while to scan all files before it starts (if there are many)

NEAT!
https://dev.yorhel.nl/ncdu

sudo apt-get install ncdu

Done...thanks!

Re: 4MB sectors - aka "Optimizing Linux with cheap flash drives"

Did you notice the date on that article? 7 years is a long time, but yes, most flash is crap. You can find out much more, and more relevant at Armbian And now there is class a1 and soon a2. It's hard to beat samsung evo or evo+ . An iozone line from my history, if you want true and accurate numbers ...

When you plug in an older usb cam
lsmod -- no sign of any cam module
ls /dev/v* -- no /dev/video0
search for UVC cam or windows8 before purchase
