2.15.1. Software Debugging Message
You can turn on the debugging message in the software to provide you run-time assistance.
To turn on the debugging message in the software, follow these steps:
- Change the DEBUG_MODE to 1 in the global.h script.
- Run script/build_sw.sh on the Nios® II Command Shell.
- Reprogram the generated software/tx_control/tx_control.elf file by running the command on the Nios® II Command Shell:
nios2-download -r -g software/tx_control/tx_control.elf
- Run the Nios® II terminal command on the Nios® II Command Shell:
nios2-terminal
When you turn on the debugging message, the following information print out:
- TI redriver settings on both TX and RX are read and displayed once after programming ELF file.
- Status message for RX EDID configuration and hotplug process
- Resolution with or without FRL support information extracted from EDID on the sink connected to the TX. This information is displayed for every TX hotplug.
- Status message for the TX link training process during TX link training.
