Often at main() when I am starting debug, and almost always after any single step, using ctrl-F9 or Debug/Run I get a popup message from the OPI Driver as detailed in the subject, and debug is halted. The board is an olimex STM32-P103 (stm32f103RB) I am using an Rlink-std. The only unusual thing I know I am doing is that I modified the vector table building code to call a specific function when a vector entry is not otherwise declared. I'll be zipping my files and looking for the note on how to send them to you. Andy. |
Strange...
Debugging with the Cortex-M3 is much easier and reliable (for debuggers) than with standard ARM cores.
If you send your project we will test on our REVA board.
At a first sight, the source of the problem could be:
1. hardware issue (JTAG connection)
2. your software modifies some of the resources used for debugging (IOs, debug registers, etc...).
