FMCOMMS1 EEPROM WRITE DATA PROBLEM

Hi,

 

We use FMCOMMS1 revision B and tried to store new calibration parameter in the EEPROM. We use the no-OS driver to do it.

 

The first test pasted successfully :

we read calibration parameter, write new calibration parameter (other frequency) and then read-back it.

It was OK.

 

Then, we power-off/power-on  the board and try to read  the parameter again.

It appears we read old calibration parameter.

 

Do you have a idea about the problem?

Is it a Pic firmware version problem?

 

 

Thanks,
