*****************************************************************************
|

|
** ChibiOS/RT port for ARM7TDMI LPC214X. **
|
||||||
|
*****************************************************************************
|
||||||
|
|
||||||
|
** TARGET **
|
||||||
|
|
||||||
|
The demo runs on an Olimex LPC-P2148 board. The port on other boards or other
|
||||||
|
members of the LPC2000 family should be an easy task.
|
||||||
|
|
||||||
|
** The Demo **
|
||||||
|
|
||||||
|
This is a minimal demo, it just blinks the leds on the board by using multiple
|
||||||
|
threads, most subsystems are disabled.
|
||||||
|
|
||||||
|
** Build Procedure **
|
||||||
|
|
||||||
|
The demo was built using the YAGARTO toolchain but any toolchain based on GCC
|
||||||
|
and GNU userspace programs will work.

- Added a minimal ARM7 demo, you can use this one as template in order to

create your application. It is easier to add subsystems back to the small

demo than remove stuff from the large one.

- Fixed a problem with the thread working area declarations, the alignment to
|
||||||
|
4 bytes boundary was not enforced. Now it is defined a new macro
|
||||||
|
WorkingArea(name, length) that takes care of both the allocation and the
|
||||||
|
alignment.
|
||||||
|
Example:
|
||||||
|
static WorkingArea(waThread1, 32);
|
||||||
|
It is expanded as:
|
||||||
|
ULONG32 waThread1[UserStackSpace(32) >> 2];
|
||||||
|
Now the demos use the new declaration style.
