Hi,

Has anyone tested booting U-boot on mx28 powered by a battery only?

From a quick glance at arch/arm/cpu/arm926ejs/mxs/spl_power_init.c ,
it does appear to support it.

I haven't tested it myself yet, but would like to hear if anyone has
been successful with such configuration.

Thanks,

Fabio Estevam

Yes, some time ago I tested this mode of operation on the M28EVK.
It ought to work, so give it a whirl. It was before Graeme did his
hacking on the power code though, so it is well possible it might
have gotten broken recently.
