I simply track the size of u-boot.img for the wandboard:

Only for the wandboard. I have a collection of usbrelais and simple
relais connected to gpios, my preffered setup currently:

https://www.amazon.de/gp/product/B07RNWLXJM/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

attached to a raspberry PI, so I have with the PI a complete "lab host"
which runs tbot incl. wifi to connect to the rest of the world ;-)

But it seems wandboard has only sd card boot, so I need for this
a sd card simulator... what I do not have yet.

Thanks!

Heiko
