- Description
When you debug programs using any of the products concerned, the following symptoms may appear:
| (1) | The debugger becomes frozen. |
| (2) | The debugger's operation gets extraordinarily slower. |
| (3) | Communication errors arise and the emulator debugger stops operating. |
| (4) | Various types of errors other than communication errors also take place successively. In this case, the emulator debugger continues operating however. |
- Conditions
This problem may occur if the following two conditions are satisfied:
| (1) | Windows XP is running on the host PC. |
| (2) | The LPT parallel interface is used for communication. |
- NOTICE:
- Depending on host PCs, the problem may not occur even if the above conditions are satisfied.
- Workaround
If you debug programs on a host PC that runs Windows XP, don't use the LPT parallel interface for communication.
If you use the LPT parallel interface, run any OS other than Windows XP on the host PC.
- Schedule of Fixing the Problem
We are now fixing the problem and going to supply the modified product on our homepage, of which we will inform you on RENESAS TOOL NEWS at a later date.
