0002 ========
0003 Description: embed-it dpu
0004
0005 CPU: MCF52259, ??MHz
0006 SRAM: 64K
0007 FLASH: 512K
0008
0009 This is a embed-it board that uses the MCF52258 Coldfire CPU.
0010 This board is running at ??MHz scaled from the internal relocation 8MHz oscillator.
0011
0012
0013
0014 OLD-STUFF from MCF52235 EVB ... we have to change it ...
0015
0016 NOTES:
0017
0018 Currently this BSP must be configured with most RTEMS features turned
0019 off as RAM usage is too high.
0020
0021 Configure as follows:
0022
0023 ```shell
0024 configure --target=m68k-rtems4.XXX --enable-rtemsbsp=mcf52235 ...
0025 ```
0026 To get the tests to compile (but not run) change the linkcmds to specify
0027 a larger sram memory region (256K works). This of course will let you
0028 compile all tests, but many or most of them wont run.
0029
0030 See testsuites/samples/minumum for an example of what type of config flags
0031 you need for this BSP!
0032
0033 In you project before you include confdefs.h, define some or all of the
0034 following:
0035
0036 #define CONFIGURE_INIT_TASK_STACK_SIZE x
0037 #define CONFIGURE_MINIMUM_TASK_STACK_SIZE x
0038 #define CONFIGURE_INTERRUPT_STACK_SIZE x
0039
0040 Note that the default stack size is 1K
0041 Note that the default number of priorities is 15
0042
0043
0044 TODO:
0045
0046 *) Add drivers for I2C, ADC, FEC
0047 *) Support for LWIP
0048 *) Recover the 1K stack space reserved in linkcmds used for board startup.
