Erasing the EEPROM stops at 0x80

Hello,

I have the problem that I cannot erase the EEPROM completely. I connect via JTAG and use the EEPROM programmer. If I erase everything with 0x00 then the fields 0x00 to 0x80 are 0x00. However, from 0x80 to 0x100 the field are still 0xFF. this pattern is repeating itself.

As EEPROM I use the 24LC512 from Microchip with 512 kbit.

Hi afkiwers,

Please check the DA14580 flash_programmer located in the SDK directory (DA1458x_SDK\5.0.4\utilities\flash_programmer).You will see that the 24LC512 EEPROM is not supported. If you want to use this EEPROM, you should add its characteristics into the user_periph_setup.h header file of the flash_programmer project.

Thanks, PM_Dialog
