+ADS GraphicsClient Plus Single Board Computer
+For more details, contact Applied Data Systems or see
+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>
+It's currently possible to mount a root filesystem via NFS providing a
+complete Linux environment. Otherwise a ramdisk image may be used. The
+board supports MTD/JFFS, so you could also mount something on there.
+Use 'make graphicsclient_config' before any 'make config'. This will set up
+defaults for GraphicsClient Plus support.
+The kernel zImage is linked to be loaded and executed at 0xc0200000.
+Also the following registers should have the specified values upon entry:
+ r0 = 0
+ r1 = 29 (this is the GraphicsClient architecture number)
+Linux can be used with the ADS BootLoader that ships with the
+newer rev boards. See their documentation on how to load Linux.
+Angel is not available for the GraphicsClient Plus AFAIK.
+There is a board known as just the GraphicsClient that ADS used to
+produce but has end of lifed. This code will not work on the older
+board with the ADS bootloader, but should still work with Angel,
+as outlined below. In any case, if you're planning on deploying
+something en masse, you should probably get the newer board.
+If using Angel on the older boards, here is a typical angel.opt option file
+if the kernel is loaded through the Angel Debug Monitor:
+----- begin angelboot.opt -----
+base 0xc0200000
+entry 0xc0200000
+r0 0x00000000
+r1 0x0000001d
+device /dev/ttyS1
+options "38400 8N1"
+baud 115200
+#otherfile ramdisk.gz
+#otherbase 0xc0800000
+exec minicom
+----- end angelboot.opt -----
+Then the kernel (and ramdisk if otherfile/otherbase lines above are
+uncommented) would be loaded with:
+ angelboot -f angelboot.opt zImage
+Here it is assumed that the board is connected to ttyS1 on your PC
+and that minicom is preconfigured with /dev/ttyS1, 38400 baud, 8N1, no flow
+control by default.
+If any other bootloader is used, ensure it accomplish the same, especially
+for r0/r1 register values before jumping into the kernel.
+Supported peripherals:
+- SA1100 LCD frame buffer (8/16bpp...sort of)
+- on-board SMC 92C96 ethernet NIC
+- SA1100 serial port
+- flash memory access (MTD/JFFS)
+- pcmcia
+- 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:
+- UCB1200 audio with new ucb_generic layer
+- everything else! :-)
+- The flash on board is divided into 3 partitions. mtd0 is where
+ the ADS boot ROM and 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!
