Revision X3 will have the hardware capability to protect the sector where
MDINK resides and should be less vulnerable to unintentional erasure.
WARNING : The Òfw -eÓ command takes a few minutes to execute. Do not power
off the board or attempt to stop the Òfw -eÓ command once it has begun. Since this
command clears the ßash and reloads MDINK, stopping the command will cause
only a partial image of MDINK to be reloaded to ROM. Next time the board is
reset, it will not function correctly.
2. DINK32 is a large Þle. Transfer time at 9600 baud will be lengthy. DINK allows the user to reset
the baud rate to baud rates up to 57600. Check your terminal emulation package for the fastest rate
supported. For example, if the fastest rate supported by your terminal emulation software is 57600,
set the baud rate to 57600 by typing "sb -k 57600" in MDINK.
3. Disconnect from the board by choosing Call | Disconnect.
4. Change the baud rate in HyperTerminal. Select File | Properties | ConÞgure | Connect To and change
the baud rate to 57600 in the space provided.
5. Reconnect to the board by selecting Call | Connect
6. Hit <return> in MDINK. You should return to the prompt.
7. Download the new dink32.src Þle:
Ñ Type "dl -ß -o ffc00000" at the MDINK prompt.
Ñ In HyperTerminal, select Transfer | Send Text File. Fill in the path to your DINK32 s-record in
the space provided and press <return>. The Þle download should begin. If your computer locks
up at this point, you will have to exit HyperTerminal, reset the board, and start over. At this
point, only MDINK remains in the ßash since the DINK32 image has been at least partially
overwritten by the aborted dl attempt. You will have to perform this entire process again.
Ñ The MDINK prompt returns when the download is complete.
CAUTION : If communication or power is lost during this process, DINK32 in
FLASHROM will be corrupted. If you can reset and get back to the MDINK
prompt, be sure to start over at step one.
8. Disconnect again by selecting Call | Disconnect.
9. Change the baud rate in HyperTerminal back to 9600 under File | Properties | ConÞgure | Connect
To and entering 9600 in the appropriate Þeld.
10. Reset the board by pressing the reset button. MDINK will boot up and will branch to the DINK32
that was just downloaded.
Part 3 Excimer Memory Map
The EXCIMER memory map is shown in Table 2. Due to the partial hardware decode used on this simple
design, unimplemented addresses generate no error signal and are aliased at multiple positions within the
address range. The suggested address columns in Table 2 represent the address that DINK uses to address
this function.
