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. + +Any contribution can be sent to nico@cam.org and will be greatly welcome! |
