- Workaround
- 3.1 In the M3T-PD308SIM
- This problem has been fixed in the M3T-PD308SIM V.3.20 Release 1.
So, use this or later version of the product.
- 3.2 In the M3T-PD308F and M3T-PD308
- We supply the problem-fixed DLL file for each product. So, please
replace the DLL file in your product with the above-mentioned one
as follows:
| (1) |
Download the problem-fixed DLL file (compressed) you want.
p308fedll.exe for the M3T-PD308F (475KB)
p308edll.exe for the M3T-PD308 (469KB)
|
| (2) |
Decompress the downloaded file to obtain either of the following files:
p308fedll.dll (V.1.41.00) for the M3T-PD308F
p308edll.dll (V.1.41.00) for the M3T-PD308
|
| (3) |
With the decompressed file, overwrite the old file with the same
name in the folder where the product has been installed.
|
| (4) |
Confirm the version of the new DLL file as follows:
| (a) |
Launch your debugger.
|
| (b) |
Open the Help menu and select the About command. The
Version dialog box appears.
|
| (c) |
On this dialog box, confirm the version of the new file is
what you want.
|
|
- 3.3 In the M3T-PD308M
- We supply the problem-fixed DLL file for the product. So, please
replace the DLL file in your product with the above-mentioned one
as follows:
| (1) |
Download the problem-fixed p308mdll.exe file (compressed: 226KB)
|
| (2) |
Decompress the downloaded file to obtain the pdbdll.dll file (V.1.11.00).
|
| (3) |
With the decompressed file, overwrite the old file with the same
name in the folder where the product has been installed.
|
| (4) |
Confirm the DLL file has been updated as follows:
| (a) |
Launch your debugger. |
| (b) |
Open the Option menu and select the Line Assemble command.
The Line Assemble dialog box appears.
|
| (c) |
Type an SCCnd instruction "SCNE A0" in the Code edit box to
line-assemble and check whether the results of execution
are correctly displayed in the Line Assemble dialog box
and the Program window.
