If you have a nanoModul-164 with 1 MB SRAM or 1 MB Flash the
memory model is different:
RAM from 0x000000 to 0x0FFFFF,
ROM from 0x1000000 to 0x1F7FFF).

Using the Bootstrap mode to transfer the required microcontroller
firmware to the nanoMODUL-164 the FlashTools maintains its
independent Flash programming capability.

5.1.2

 

FlashTools for Windows

Flash is a highly functional means of storing non-volatile data. One of
its advantages is the possibility of on-board programming.
Programming tools for the Flash device are delivered with the
nanoMODUL-164 in the form a set of executable and binary files that
run under Windows9x/NT. These tools make use of the Bootstrap
mode to transfer executable code to the nanoMODUL-164 that, in
turn, download user code into the Flash. Additionally, the re-
programmable Flash device on the nanoMODUL-164 enables easy
update of user code and the target application in which the
nanoMODUL-164 has been implemented.

Currently the nanoMODUL-164 can be populat with three different
sized Flash devices: a 29F200 with 256 kByte, a 29F400 with 512
kByte or a 29F800 with 1 MB.

FlashTools always uses the Bootstrap mode to transfer the required
microcontroller firmware to the nanoMODUL-164. Hence, there is no
restriction in using the Flash-Memory for storing user code.

Before Flash programming FlashTools will adjust the internal Chip
Select Unit and the bus configuration of the microcontroller during
the Bootstrap download. This results in the following programming
Memory-Model:

♦

 

Flash addressable at 00:0000H-07:FFFFH
 (up to 512 kByte Flash)

♦

 

RAM addressable at 08:00000H-0F:FFFFH
 (up to 512 MB RAM)
