| 2 | |
| 3 | For more details, contact Applied Data Systems or see |
| 4 | http://www.applieddata.net/products.html |
| 5 | |
| 6 | The original Linux support for this product has been provided by |
| 7 | Nicolas Pitre <nico@cam.org>. Continued development work by |
| 8 | Woojung Huh <whuh@applieddata.net> |
| 9 | |
| 10 | Use 'make graphicsmaster_config' before any 'make config'. |
| 11 | This will set up defaults for GraphicsMaster support. |
| 12 | |
| 13 | The kernel zImage is linked to be loaded and executed at 0xc0400000. |
| 14 | |
| 15 | Linux can be used with the ADS BootLoader that ships with the |
| 16 | newer rev boards. See their documentation on how to load Linux. |
| 17 | |
| 18 | Supported peripherals: |
| 19 | - SA1100 LCD frame buffer (8/16bpp...sort of) |
| 20 | - SA1111 USB Master |
| 21 | - on-board SMC 92C96 ethernet NIC |
| 22 | - SA1100 serial port |
| 23 | - flash memory access (MTD/JFFS) |
| 24 | - pcmcia, compact flash |
| 25 | - touchscreen(ucb1200) |
| 26 | - ps/2 keyboard |
| 27 | - console on LCD screen |
| 28 | - serial ports (ttyS[0-2]) |
| 29 | - ttyS0 is default for serial console |
| 30 | - Smart I/O (ADC, keypad, digital inputs, etc) |
| 31 | See http://www.applieddata.com/developers/linux for IOCTL documentation |
| 32 | and example user space code. ps/2 keybd is multiplexed through this driver |
| 33 | |
| 34 | To do: |
| 35 | - everything else! :-) |
| 36 | |
| 37 | Notes: |
| 38 | |
| 39 | - The flash on board is divided into 3 partitions. mtd0 is where |
| 40 | the zImage is stored. It's been marked as read-only to keep you |
| 41 | from blasting over the bootloader. :) mtd1 is |
| 42 | for the ramdisk.gz image. mtd2 is user flash space and can be |
| 43 | utilized for either JFFS or if you're feeling crazy, running ext2 |
| 44 | on top of it. If you're not using the ADS bootloader, you're |
| 45 | welcome to blast over the mtd1 partition also. |
| 46 | |
| 47 | - 16bpp mode requires a different cable than what ships with the board. |
| 48 | Contact ADS or look through the manual to wire your own. Currently, |
| 49 | if you compile with 16bit mode support and switch into a lower bpp |
| 50 | mode, the timing is off so the image is corrupted. This will be |
| 51 | fixed soon. |
