TM4C1230C3PM: Question about EEPROM

Other Parts Discussed in Thread: UNIFLASH

Hi,

I have a question about chis MCU.

I know that this type of CPU has Eeprom. In my code I'm using functions EEPROMProgram and EEPROMRead to deal with it.

Now, we need to re-flash the CPU using uniFlash, so I want to understand if the data is not erased after make the whole chip erase and the programming procedure.

Or if it is a flag to leave the eeprom untouched.

Thanks,

Marco.

Hi,

When you use Uniflash to reflash the flash memory, the EEprom is not affected. The only time EEprom is erased is when you do a 'unlock' operation on the device. An unlock operation is a mass-erase operation that will revert the device to its factory setting.

Hi,

thanks for the answer. The unlock operation can be performed using uniFlash? I have to be carefull on what I press?

Thanks.
