give the command to load the desired good firmware into FX2 microcontroller's external EEPROM using CyControl, CyConsole, OpenFutNet (Windows OS, all SW tools using CyAPI.lib or CyUSB.dll) ;

The CyConsole's "Lg EEPROM" button, CyControl's "64KB EEPROM" button and OpenFutNet's "Program USB: write IIC EEPROM" button call the loadEEPROM() function. This function is used to program 64-Kbyte EEPROMs. When the button (CyConsole's Lg EEPROM button, CyControl's EEPROM button or OpenFutNet's IIC button) is clicked, the user is prompted to select a (.iic) file to load into the EEPROM. This button first downloads the Vend_Ax(_Fx2).bix file, then sends the 0xA9 vendor request to program the EEPROM. |
The CyConsole/CyControl/OpenFutNet program will load
(HIDDEN STEP 1) an intermediate good firmware supporting EEPROM programming (normally the 2nd stage bootloader Vend_Ax.hex ) in RAM;

The CyConsole's "S EEPROM" button is used to program 256-byte EEPROMs. When this button is clicked, the user is prompted to select a (.iic) file to load into the EEPROM. This button first downloads the Vend_Ax(_Fx2).bix file, then sends the 0xA2 vendor request to program the EEPROM. This button should not be used. |
