Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

ADS GraphicsClient Plus 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@fluxnic.net>. 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.eurotech-inc.com/linux-sbc.asp 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! :-)
|
|
|
|
Notes:
|
|
|
|
- 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.
