This file contains status information for the port of U-Boot to the

The support for the Galileo Evaluation board is fairly minimal now.
|
|
It's sufficient to boot Linux, but doesn't provide too much more than
|
|
what's required to do this.
|
|
|
|
Both DUART channels are supported (to use the second one, you have to
|
|
modify the board -- see the schematics for where to solder on the
|
|
devices module). The ethernet ports are supported, and the MPSC is
|
|
supported as a console driver. (keep in mind that the kernel has no
|
|
support for this yet)
|
|
|
|
There are still occaisonal lockups with the MPSC console driver due to
|
|
(we think!) overrun problems. If you're looking for something stable
|
|
to use for Linux development, consider sticking with the DUART console
|
|
for now.
|
|
|
|
Automatic memory sizing mostly works. We've had problems with some
|
|
combinations of memory. Please send us email if you're having trouble
|
|
with respect to the memory detection.
|
|
|
|
Right now, only the 512k boot flash is supported. Support for the
|
|
16MB flash on the devices module is forthcoming. Right now the flash
|
|
is stored at the 256k boundry in flash, wasting a whole sector (64k!)
|
|
for environment data. This isn't really a big deal since we're not
|
|
using the 512k for anything else. (Just U-Boot and the environment)
|
|
|
|
Finally, here is a sample output session:
|
|

The default configuration should be correct for the evaluation board,
|
|
as it's shipped from Galileo. Keep in mind that the default baudrate
|
|
is set to 38400, 8N1.
|
|
|
|
Good luck, and make sure to send any bugreports to us (or the
|
|
u-boot-users list).
