A Note on Using
Emulation Probe M30850T-EPB
|
|---|
Please take note of the following problem in using the M30850T-EPB emulation
probe (the product is used for the M32C/80, M32C/84, M32C/85, and M32C/86
groups, M32C/80 series of MCUs in combination with the PC7501 emulator):
- Description
If any program is downloaded to the emulator system that uses the
M30850T-EPB, flash-ROM erase errors arise with the following error message accompanied:
ERROR 16258: Flash ROM deletion error occurred.
- Condition
This problem may occur if the system using the probe is operating
at a main-clock frequency (XIN) of 16 MHz or lower.
- Workaround
This problem can be circumvented by using the problem-fixed firmware
and MCU files. So please replace yours with them as follows:
| (1) |
Download the m30850f.s firmware file and the m30850_a.mcu MCU file from HERE. |
| (2) |
Copy the downloaded m30850f.s firmware file into the folder*
where the M3T-PD308F emulator debugger resides.
| * |
If the M3T-PD308F has been installed as the default, this folder is c:/mtool/pd308f in its full pathname expression. |
|
| (3) |
Copy the downloaded m30850_a.mcu MCU file into the "mcufiles"
folder* under the folder where the M3T-PD308F resides.
| * |
If the M3T-PD308F has been installed as the default, this folder is c:/mtool/pd308f/mcufiles in its full pathname expression. |
|
| (4) |
Check to see that the problem-fixed MCU file has been successfully installed as follows:
| (a) |
Launch the M3T-PD308F.
The Init dialog box appears. |
| (b) |
Select the MCU tab and click the Refer button to open the File Selection dialog box. |
| (c) |
Select "m30850_a.mcu" as your MCU file in the dialog box. |
| (d) |
If you see "m30850_a.mcu" displayed in the MCU area in the MCU tab, the problem-fixed MCU file has been successfully installed. |
|
- Schedule of Fixing the Problem
We plan to fix this problem in our next release of the M3T-PD308F emulator debugger.
- Another Problems Encountered in M30850T-EPB
If a CPU rewrite program is stored in expanded emulation memory, this program may run away. So, store it in on-chip RAM or an external resource in the Target system.
Note, however, that this problem arises only in emulation using the emulator; it does not arises in actual MCUs.
