Hi,

I am using the sample code provide by Freescale(NXP) in the project KT9Z1-638-REFAPP.

The Eeprom erased when I reset or power off the board.

I am using the function, EEPROM_WriteCalibValue as it is.

best regards

Hello,

If the EEPROM is erased, there must be a function that erases it.

Have you tried to halt the execution just after POR, check the EEPROM and step the code?

Thanks,

BR, Daniel

Hello Daniel,

thank you for your response,

I did step by step , but I was using library from NXP ( executable code), so I could not go through their code.when I replaced the CPU, and It seems every thing is working fine so far.

I think the problem is resolved !!
