Debug

Function

A breakpoint after a conditional jump is missed when wait-states are used

Description

A hardware breakpoint set on a code line immediately following a conditional jump will not be hit when the application uses a wait-state. This also affects single-stepping C code through a conditional jump. A conditional jump could be if-else, for-loops, or switch-case statements.

Note: This erratum affects debug mode only.

Workaround

1) Insert a __no_operation() immediately before the intended line of code that a breakpoint will be set on. For example:


if (a) {
    __no_operation();   \\ workaround
    \\ your application code -- set breakpoint
}
else {
    __no_operation();   \\ workaround
    \\ your application code -- set breakpoint
}



Or

2) Operate the debugger in Free Run mode.

Or

3) Single-step on disassembler level
