M-Station Baseboard
Using the navigation buttons, browse to the
C:\NECTools32\PRC
directory, where you should find the
.PRC file for the device you wish to program. For example, for the µPD78F0338 on the EV0338 micro-
board, you would find the file “78F0338.PRC”. If you do not have the .PRC file for the flash device you
wish to program, contact NEC Electronics America.
Select the appropriate .PRC file so that its name shows in the
File Name
box and click
Open
. Clicking
Cancel
at this point closes the FP4MST program without accessing the M-Station.
9.1.1
Comparison of .PRC Settings to M-Station V
DD
and V
PP
Configuration
Once you select the .PRC file, the FP4MST program checks the V
DD
and V
PP
voltages specified there
against those set by the OPTMST program. If the values don’t match, then you will receive an error
message stating that the recorded setting is incorrect:
1. Disconnect power from the M-Station.
2. Recheck the appropriate settings for V
DD
and V
PP
and correct the JP3 and JP4 jumpers if
necessary.
3. Run OPTMST and set the JP3 and JP4 options to match the settings on the M-Station.
4. You may also correct the configuration by clicking
Yes
in response to the error messages.
The FP4MST program cannot check the actual settings of JP3 and JP4 on the M-Station to verify
voltages. It can only check the settings in the flash-programming options set by OPTMST. It checks
these settings before applying power to the V
DD
or V
PP
lines on the M-Station.
9.1.2
FP4MST Initialization and Signature Check of Flash Device
After loading and checking the .PRC file information, the FP4MST program applies power to the flash-
programming interface V
DD
and V
PP
lines, and attempts to initialize the flash device for operation.
