µVISION DEBUGGER: µVISION may perform endless memory read accesses
Information in this knowledgebase article applies to:
Under certain circumstances, µVision may perform endless memory read accesses with any 8051 target debugger. This can happen under the following conditions:
In most cases, a user will not notice this problem, but since the bandwidth to the target debugger is usually limited, the debug connection might slow down. It may also happen that the RUN button stays greyed out and the STOP button stays active forever, after a single step has been executed.
There was an issue in the µVision target debugger, which caused these endless read accesses.
You may download the attached file and extract the ZIP file into the folder C:\Keil_v5\C51\BIN\. If you have chosen a different installation folder, the path needs to be adapted accordingly. This updates the S8051.dll file.
