0001 Motorola MCF52235EVB
0002 ====================
0003
0004 CPU: MCF52235, 60MHz
0005 SRAM: 32K
0006 FLASH: 256K
0007
0008 This is a Motorola evaluation board that uses the MCF52235 Coldfire CPU.
0009 This board is running at 60MHz scaled from a 25MHz oscillator.
0010
0011
0012 NOTES:
0013
0014 Currently this BSP must be configured with most RTEMS features turned
0015 off as RAM usage is too high.
0016
0017 Configure as follows:
0018
0019 ```shell
0020 configure --target=m68k-rtems4.XXX --enable-rtemsbsp=mcf52235 \
0021 ```
0022
0023 To get the tests to compile (but not run) change the linkcmds to specify
0024 a larger sram memory region (256K works). This of course will let you
0025 compile all tests, but many or most of them wont run.
0026
0027 See testsuites/samples/minumum for an example of what type of config flags
0028 you need for this BSP!
0029
0030 In you project before you include confdefs.h, define some or all of the
0031 following:
0032
0033 ```c
0034 #define CONFIGURE_INIT_TASK_STACK_SIZE x
0035 #define CONFIGURE_MINIMUM_TASK_STACK_SIZE x
0036 #define CONFIGURE_INTERRUPT_STACK_SIZE x
0037 ```
0038
0039 Note that the default stack size is 1K
0040 Note that the default number of priorities is 15
0041
0042
0043 TODO:
0044
0045 *) Add drivers for I2C, ADC, FEC
0046 *) Support for LWIP
0047 *) Recover the 1K stack space reserved in linkcmds used for board startup.
