| 8 | The original Linux support for this product has been provided by | ||
| 9 | Nicolas Pitre <nico@fluxnic.net>. Continued development work by | ||
| 10 | Woojung Huh <whuh@applieddata.net> | ||
| 11 | |||
| 12 | Use 'make graphicsmaster_config' before any 'make config'. | ||
| 13 | This will set up defaults for GraphicsMaster support. | ||
| 14 | |||
| 15 | The kernel zImage is linked to be loaded and executed at 0xc0400000. | ||
| 16 | |||
| 17 | Linux can be used with the ADS BootLoader that ships with the | ||
| 18 | newer rev boards. See their documentation on how to load Linux. | ||
| 19 | |||
| 20 | Supported peripherals | ||
| 21 | ===================== | ||
| 22 | |||
| 23 | - SA1100 LCD frame buffer (8/16bpp...sort of) | ||
| 24 | - SA1111 USB Master | ||
| 25 | - on-board SMC 92C96 ethernet NIC | ||
| 26 | - SA1100 serial port | ||
| 27 | - flash memory access (MTD/JFFS) | ||
| 28 | - pcmcia, compact flash | ||
| 29 | - touchscreen(ucb1200) | ||
| 30 | - ps/2 keyboard | ||
| 31 | - console on LCD screen | ||
| 32 | - serial ports (ttyS[0-2]) | ||
| 33 | - ttyS0 is default for serial console | ||
| 34 | - Smart I/O (ADC, keypad, digital inputs, etc) | ||
| 35 | See http://www.eurotech-inc.com/linux-sbc.asp for IOCTL documentation | ||
| 36 | and example user space code. ps/2 keybd is multiplexed through this driver | ||

| 41 | - everything else! :-) | ||
| 42 | |||
| 43 | Notes | ||
| 44 | ===== | ||
| 45 | |||
| 46 | - The flash on board is divided into 3 partitions. mtd0 is where | ||
| 47 | the zImage is stored. It's been marked as read-only to keep you | ||
| 48 | from blasting over the bootloader. :) mtd1 is | ||
| 49 | for the ramdisk.gz image. mtd2 is user flash space and can be | ||
| 50 | utilized for either JFFS or if you're feeling crazy, running ext2 | ||
| 51 | on top of it. If you're not using the ADS bootloader, you're | ||
| 52 | welcome to blast over the mtd1 partition also. | ||
| 53 | |||
| 54 | - 16bpp mode requires a different cable than what ships with the board. | ||
| 55 | Contact ADS or look through the manual to wire your own. Currently, | ||
| 56 | if you compile with 16bit mode support and switch into a lower bpp | ||
| 57 | mode, the timing is off so the image is corrupted. This will be | ||
| 58 | fixed soon. | ||
| 59 | |||
