Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
|
|
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.
|
|
|
|

|
|
- 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)

|
|
|
|
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.
