SerialICE Kernels
|
||
|
|
|
||
|
|
The SerialICE package provides a number of example SerialICE Kernels. These
|
||
|
|
are located in the bsps directory. To build an SerialICE Kernel
|
||
|
|
simply move to the bsps directory and type make. This will list all of
|
||
|
|
the kernels that are currently provided, together will instructions for
|
||
|
|
building them. If you have built your own board, you will probably need
|
||
|
|
to modify the kernel to make it work on
|
||
|
|
your new board.
|
||
|
|
|
||
|
|
Once you have built the S-record file you
|
||
|
|
are ready to make ROMS.

SerialICE protocol
|
||
|
|
|
||
|
|
The SerialICE Kernel is a small (less than 1K bytes) program that is ROM-resident
|
||
|
|
on your Target board.
|
||
|
|
|
||
|
|
Principle Features:
|
||
|
|
|
||
|
|
� Neither uses nor flushes the caches - runs from k1seg.
|
||
|
|
� Does initialize at least one block of RAM - this usually just means that
|
||
|
|
it initializes the DRAM controller.
|
||
|
|
� Uses Interrupt-driven Serial I/O - Actually interrupts are only used to
|
||
|
|
wakeup the kernel when the application is running.
|
||
|
|
� Runs the Application on powerup - If no real application is included
|
||
|
|
in the ROM, the processor sits in a branch-to-self loop until
|
||
|
|
the wakeup request is received.
|
||
|
|
� Does not include software emulation of floating-point or multiply/divide.
|
||
|
|
� Does not include software for instruction emulation.
