Q:
I have a different memory map on my custom hardware as compared to the develop-
ment board. What changes am I required to make to modify the RZK demo project to suit
my custom hardware in the ZDSII environment?
A:
RZK uses the bootup files provided by ZDS II. This means that there are no separate
hardware configuration files required to configure the chip selects and the memory map.
So if your custom hardware features a different memory map as compared to the one pro-
vided in the demo programs for the development platform, then the following changes
must suit your custom hardware:
Modify the ROM and RAM address space to suit your memory map under
Project
→
Settings
→
Linker
→
Address Space
→
ROM
and
RAM
address spaces.
Incorporate the corresponding changes to the
Chip Selects
, the
Program Counter
and
the
Stack Pointer
under
Project
→
Settings
→
Debugger
→
Setup
,
Program Coun-
ter
,
Stack Pointer Long
and the
Chip Select
Registers. Take special care while enabling/
disabling the internal Flash and internal SRAM.
The only change that may be required in the configuration files is for the wait states of the
internal flash. The following code string can be changed, depending on your requirements:
FLASH_CTRL = (FLASH_CTRL & ~FLASH_CTRL_7_WS) | FLASH_CTRL_3_WS;
This code string is available in the
RZK_HW_Init()
function, which is located in the
eZ80Hw_Conf_ZDS.c
file.
