| |
| 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: |
| |
| U-Boot 1.0.0-pre1 (Jun 6 2001 - 12:45:11) |
| |
| Initializing... |
| CPU: MPC7400 (altivec enabled) v2.9 |
| Board: EVB64260 |
| DRAM: 256 MB |
| FLASH: 512 kB |
| In: serial |
| Out: serial |
| Err: serial |
| |
| => |
| |
| 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). |
