Configure required pins for trace output
1. Create a file for the device
LPC4357.ini
/********************************************************************* * Configure pins to enable the trace port * *********************************************************************/ _WDWORD(0x40086790, 0x00000032); // Configure PF_4 AS FUNC2 _WDWORD(0x40086794, 0x00000033); // Configure PF_5 as FUNC3 _WDWORD(0x40086798, 0x00000033); // Configure PF_6 as FUNC3 _WDWORD(0x4008679C, 0x00000033); // Configure PF_7 as FUNC3 _WDWORD(0x400867A0, 0x00000033); // Configure PF_8 as FUNC3
2. Set the file as initialization file
- Open the dialog "Options for Target - Debug".
- Set the created file as Initialization File.
Configure µVision for ETM trace
- Click Settings to open the "Target Driver Setup" dialog.
- Click the Trace tab.
