  • Configure Flash Size

After users apply the pin configurations, GProgrammer reads and displays the external Flash ID based on which the Flash Size is automatically set.

Tip:

Before clicking Apply, make sure external flash memories are correctly connected to the target board in accordance with pin configurations. Incorrect connections lead to failures in communications between external flash and the board.

Users need to manually set the Flash Size when GProgrammer fails to get the flash size based on the accessed flash ID.
