Chip Configuration
Click on the left side of the main interface of GProgrammer to open the Chip Configuration interface.

GProgrammer allows users to set the parameters (including USER Parameters and ROM Parameters) stored in the NVDS area.
- USER Parameters: user-defined parameters that can be added, deleted, and modified
- ROM Parameters: ROM parameters stored on GR551x SoCs, which can be modified only by users. Neither parameter addition nor deletion is allowed.
Note:
- The default ROM parameters listed in the interface are stored in the nvds_config.json file in the config folder. The parameters are not results accessed in real time from the NVDS area. For more information about ROM parameters, see Table 7.
- Click
in the upper-right corner of the Chip Configuration interface to enable display of complete value contents of a parameter.
- Look up parameters quickly by using the
screening box in the upper-right corner of the interface.
