This post describes what is Config file and what is included in it.
Definition :
Config file named “fw_rdc200.cfg” is a set of parameters/flags that are used in firmware of RDC200.
If this config file is NOT downloaded or NOT matched with Hardware display module(RDC2OO and panel configuration), display part can’t work normally.
Full mandatory download files are described here as “Which files should be downloaded for display?”
Config file can be provided as below method :
If you use Vista Studio™, this file is automatically generated.
- Items related to bootlogo or debug message should be modified directly.
If you use Vista Cube™, you should create or modify manually all items from template file.
- e.g. A RDC200/RDP550F template file is in $RDC200_INIT_PATH\download\rdp550f/fw_rdc200.cfg
Two use cases :
Use Case 1 : If you want to place bootlogo image on the top-center of the screen,
- Edit
pox_x = 900andpox_y = 10in a fw_rdcx00.config file. - Download it via VistStudio™ or VistaCube™ ( you can download only one config item )
- Reboot.
Use Case 2 : If you want to display debug messages to the serial port,
- Edit
debug_en = 1in a fw_rdcx00.config file. - Download it via VistStudio™ or VistaCube™ ( you can download only one config item ).
- Reboot.
- Connect Uart serial port of RDC to your Serial port
- RXD/TXD singal is LVCMOS level.
- Baudrate : 14400

Small tips for VistaStudio™ users
You can compare the converted field values to the input config item via Memory Viewer of VistaStudio™.
