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