7 The support for the Galileo Evaluation board is fairly minimal now.
8 It's sufficient to boot Linux, but doesn't provide too much more than
9 what's required to do this.
11 Both DUART channels are supported (to use the second one, you have to
12 modify the board -- see the schematics for where to solder on the
13 devices module). The ethernet ports are supported, and the MPSC is
14 supported as a console driver. (keep in mind that the kernel has no
17 There are still occaisonal lockups with the MPSC console driver due to
18 (we think!) overrun problems. If you're looking for something stable
19 to use for Linux development, consider sticking with the DUART console
22 Automatic memory sizing mostly works. We've had problems with some
23 combinations of memory. Please send us email if you're having trouble
24 with respect to the memory detection.
26 Right now, only the 512k boot flash is supported. Support for the
27 16MB flash on the devices module is forthcoming. Right now the flash
28 is stored at the 256k boundry in flash, wasting a whole sector (64k!)
29 for environment data. This isn't really a big deal since we're not
30 using the 512k for anything else. (Just U-Boot and the environment)
32 Finally, here is a sample output session:
34 U-Boot 1.0.0-pre1 (Jun 6 2001 - 12:45:11)
37 CPU: MPC7400 (altivec enabled) v2.9
47 The default configuration should be correct for the evaluation board,
48 as it's shipped from Galileo. Keep in mind that the default baudrate
