Description: Motorola MCF52235EVB
============================================================================
CPU: MCF52235, 60MHz
SRAM: 32K
FLASH: 256K
This is a Motorola evaluation board that uses the MCF52235 Coldfire CPU.
This board is running at 60MHz scaled from a 25MHz oscillator.
============================================================================
NOTES:
Currently this BSP must be configured with most RTEMS features turned
off as RAM usage is too high.
Configure as follows:
configure --target=m68k-rtems4.XXX --enable-rtemsbsp=mcf52235 \
To get the tests to compile (but not run) change the linkcmds to specify
a larger sram memory region (256K works). This of course will let you
compile all tests, but many or most of them wont run.
See testsuites/samples/minumum for an example of what type of config flags
you need for this BSP!
In you project before you include confdefs.h, define some or all of the
following:
#define CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS
#define CONFIGURE_INIT_TASK_STACK_SIZE x
#define CONFIGURE_MINIMUM_TASK_STACK_SIZE x
#define CONFIGURE_INTERRUPT_STACK_SIZE x
Note that the default stack size is 1K
Note that the default number of priorities is 15
============================================================================
TODO:
*) Add drivers for I2C, ADC, FEC
*) Support for LWIP
*) Update the coverhd.h (calling overheads) page 21 of the BSP guide
*) Recover the 1K stack space reserved in linkcmds used for board startup.
============================================================================
