\subsection{Debugging}\label{troubleshootingdebug}
|
||||
|
||||
Similar to other projects working with hardware OpenCore supports auditing and debugging.
|
||||
The use of \texttt{NOOPT} or \texttt{DEBUG} build modes instead of \texttt{RELEASE}
|
||||
can produce a lot more debug output. With \texttt{NOOPT} source level debugging with
|
||||
GDB or IDA Pro is also available. For GDB check
|
||||
\href{https://github.com/acidanthera/OcSupportPkg/tree/master/Debug}{OcSupport Debug}
|
||||
page. For IDA Pro you will need IDA Pro 7.3 or newer.
|
||||
|
||||
To obtain the log during boot you can make the use of serial port debugging. Serial port
|
||||
debugging is enabled in \texttt{Target}, e.g. \texttt{0xB} for onscreen with serial. OpenCore
|
||||
uses \texttt{115200} baud rate, \texttt{8} data bits, no parity, and \texttt{1} stop bit.
|
||||
For macOS your best choice are CP2102-based UART devices. Connect motherboard \texttt{TX}
|
||||
to USB UART \texttt{GND}, and motherboard \texttt{GND} to USB UART \texttt{RX}. Use
|
||||
\texttt{screen} utility to get the output, or download GUI software, such as
|
||||
\href{https://freeware.the-meiers.org}{CoolTerm}.
|
||||
|
||||
Remember to enable \texttt{COM} port in firmware settings, and never use USB cables longer
|
||||
than 1 meter to avoid output corruption. To additionally enable XNU kernel serial output
|
||||
you will need \texttt{debug=0x8} boot argument.
