CDCE72010 EEPROM writing

Other Parts Discussed in Thread: CDCE72010

our cusomter is asking if there is a simple way to write register settings permanently into EEPROM? he followed the datasheet description, but he couldn't make it work. 

Does the CDCE72010 EVM support that feature, i.e. EEPROM writing? if so, the cusotmer can get an EVM and use the EVM as a controller . 

Thanks!

    Both the older and newer CDCE72010 GUI's allow writing the EEPROM.  It's under tool/SPI debug.

    The older one allows writing it 'locked' so it can't be written again without magic secret instructions.

    I think the newer GUI removed the write locked function, if I remember correctly.  If that's what they want they should use the older GUI app.

    He can also do it with direct writes with his own app through the SPI port.  We have been doing that all along and it has been working as described in the data sheet.
