Using DebugPrintF and Forbid

[capehill]

Does DebugPrintF enter wait state? In other words, should DebugPrintFs be removed out of Forbid/Permit context?

No, DebugPrintF() waits on the "done" bit in the serial device register. It uses no interrupts and hangs the machine while it outputs the string of characters.

Forbid/Permit calls are unnecessary for DebugPrintF() to work and will have no effect on it.

Thanks for the information.
