1 | Description: Motorola MCF52235EVB |
---|
2 | ============================================================================ |
---|
3 | CPU: MCF52235, 60MHz |
---|
4 | SRAM: 32K |
---|
5 | FLASH: 256K |
---|
6 | |
---|
7 | This is a Motorola evaluation board that uses the MCF52235 Coldfire CPU. |
---|
8 | This board is running at 60MHz scaled from a 25MHz oscillator. |
---|
9 | |
---|
10 | ============================================================================ |
---|
11 | NOTES: |
---|
12 | |
---|
13 | Currently this BSP must be configured with most RTEMS features turned |
---|
14 | off as RAM usage is too high. |
---|
15 | |
---|
16 | Configure as follows: |
---|
17 | configure --target=m68k-rtems4.XXX --enable-rtemsbsp=mcf52235 \ |
---|
18 | |
---|
19 | To get the tests to compile (but not run) change the linkcmds to specify |
---|
20 | a larger sram memory region (256K works). This of course will let you |
---|
21 | compile all tests, but many or most of them wont run. |
---|
22 | |
---|
23 | See testsuites/samples/minumum for an example of what type of config flags |
---|
24 | you need for this BSP! |
---|
25 | |
---|
26 | In you project before you include confdefs.h, define some or all of the |
---|
27 | following: |
---|
28 | |
---|
29 | #define CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS |
---|
30 | #define CONFIGURE_INIT_TASK_STACK_SIZE x |
---|
31 | #define CONFIGURE_MINIMUM_TASK_STACK_SIZE x |
---|
32 | #define CONFIGURE_INTERRUPT_STACK_SIZE x |
---|
33 | |
---|
34 | Note that the default stack size is 1K |
---|
35 | Note that the default number of priorities is 15 |
---|
36 | |
---|

38 | TODO: |
---|
39 | |
---|
40 | *) Add drivers for I2C, ADC, FEC |
---|
41 | *) Support for LWIP |
---|
42 | *) Update the coverhd.h (calling overheads) page 21 of the BSP guide |
---|
43 | *) Recover the 1K stack space reserved in linkcmds used for board startup. |
