7The support for the Galileo Evaluation board is fairly minimal now.
8It's sufficient to boot Linux, but doesn't provide too much more than
9what's required to do this.
10
11Both DUART channels are supported (to use the second one, you have to
12modify the board -- see the schematics for where to solder on the
13devices module). The ethernet ports are supported, and the MPSC is
14supported as a console driver. (keep in mind that the kernel has no
15support for this yet)
16
17There are still occaisonal lockups with the MPSC console driver due to
18(we think!) overrun problems. If you're looking for something stable
19to use for Linux development, consider sticking with the DUART console
20for now.
21
22Automatic memory sizing mostly works. We've had problems with some
23combinations of memory. Please send us email if you're having trouble
24with respect to the memory detection.
25
26Right now, only the 512k boot flash is supported. Support for the
2716MB flash on the devices module is forthcoming. Right now the flash
28is stored at the 256k boundry in flash, wasting a whole sector (64k!)
29for environment data. This isn't really a big deal since we're not
30using the 512k for anything else. (Just U-Boot and the environment)

32Finally, here is a sample output session:

34U-Boot 1.0.0-pre1 (Jun 6 2001 - 12:45:11)

37 CPU: MPC7400 (altivec enabled) v2.9
38 Board: EVB64260
39 DRAM: 256 MB
40 FLASH: 512 kB
41 In: serial
42 Out: serial
43 Err: serial

47The default configuration should be correct for the evaluation board,
48as it's shipped from Galileo. Keep in mind that the default baudrate
49is set to 38400, 8N1.
50
51Good luck, and make sure to send any bugreports to us (or the
52u-boot-users list).
