A Note on Using Emulator Debugger
M3T-PD30F V.1.00 Release 1
|
|---|
Please take note of the following problem in using the M3T-PD30F emulator debugger for the M16C/60 series MCUs:
- On using the MR trace window
- Version Concerned
M3T-PD30F V.1.00 Release 1
- Description
When the MR trace window is opened to display the execution history of a task, the error message saying "Interrupt handler issued a system call that can be issued from only tasks." may appear, resulting in the incorrect execution history being displayed.
- 2.1 Conditions
- This problem occurs if fetching the reit instruction executed in a system call and writing data into OS's resource by the M3T-MR30 are performed in the same cycle.
- Workaround
This problem can be circumvented by using the problem-fixed DLL file.
So, please replace the DLL file in your product with the above-mentioned one as follows:
| (1) | Download the problem-fixed DLL file, p30frtoswin.exe (187KB). |
| (2) | Decompress the downloaded file to obtain the p30fRTOSWin.dll file (V.1.10.10). |
| (3) | With the decompressed file, overwrite the old p30fRTOSWin.dll file in the folder where the M3T-PD30F resides. |
| (4) | Confirm the version of the new DLL file as follows:
| (a) | Launch the M3T-PD30F. |
| (b) | Open the Help menu and select About; then the Version dialog box opens, on which the version of the problem-fixed DLL file will be displayed. |
| (c) | Confirm the version is V.1.10.10. |
|
- Schedule of Fixing the Problem
We plan to fix this problem in our next release of the product.
